Managing stockpile inventory, that is, finding a solution for accurate volume measurement and easy inventory management, is one of the biggest challenges in the mining industry. When it comes to stockpile volume measurementsstockpiles do not conform to a perfect shape. A photogrammetric survey with a fine ground sampling distance GSD, which indicates the actual distance each pixel represents is able to better describe irregular stockpiles in detail. Horizontally, high-resolution photogrammetric results create more precise stockpile models, and thus better volume measurement accuracy than ones interpolated from certain measured points.
Vertically, they lower the uncertainty in Z values, which is proportional to the resolution.2021 wrx
For example, flatter stockpiles will benefit more from a high GSD than taller stockpiles. Larger uncertainty in vertical direction in low GSD datasets Pix4Dmapper allows you to adjust the reference base above which you want the volume to be measured.Apni aukat mat bhulo in english
The error of the height values will have much more influence for the bottom flat part than the tip. This also explains how important to well-define the base surface is in order to obtain an accurate volume measurement.
Standard stockpile is the most generic stockpile type. It is constructed with basic bucket loading and dumping techniques. Ramp stockpile is constructed high, with a narrow ramp, and is optimal for storing a large amount of materials in a very limited area.
Bin stockpile is a common stockpile type. Materials are stored in a row of three-sided bins, with enclosures consisting of a hard floor and walls.
It is the best solution to keep different materials separate. In addition to generating precise 3D models for the purpose of measurements, Pix4Dmapper and Pix4Dbim are used for stockpile measurement because of their ability to customize base surfaces. The software provides 6 different base surface-defining options in its volume management module; for more complicated conditions, users can import their own base surface or ground-surveyed points which form the base surface and use them as a base to calculate stockpile volumes.

In an effort to improve worker safety and boost efficiency, the largest mining company in Ukraine launched a first for the country: drones. Quality, efficiency - and drones.Whether you need to survey drainage needs on a farm or assess work at a construction site, few modern tools are more helpful than drones. With an eye-in-the-sky view, you can get a better idea of what needs to be done and where much more quickly than you ever would through an on-the-ground inspection.
Of course, when it comes to business and agricultural needs, many drone users need much more than an aerial image—and this is where drone mapping apps come in. With advanced data analysis and other useful tools, the right app can transform the images captured by your drone into actionable information. But which DJI drone mapping apps offer the best value for your money? As one of the largest drone mapping apps on the market, DroneDeploy has quickly made a name for itself thanks to its user-friendly model that allows for integration with other drone apps such as Flyte, Skymatics, and WhiteClouds.

The Top 3 Drone Mapping Apps for DJI Drones
Each package has been created to answer the specific challenges of drone mapping in each sector as well as find solutions to inherent problems. For instance, the Mining software package can help to identify issues with slope stability and other geohazards whilst performing automated stockpile calculations.
The day trial gives you access to all of the features to be able to make an informed decision. You can then choose to pay as you use one month at a timepay annually or buy a lifetime licence. The downside: Because of the wealth of features, Pix4D software can be a little overwhelming. This course was developed in response to requests from customers who wanted to get the most out of their subscription.
The course takes you all the way through from data collection to processing and is great for beginners and more experienced drone surveyors. They offer dozens of different software packages with drone mapping software representing a small percentage of their annual revenue.
For the uninitiated you can find a great definition of 3D mesh modelling here. The downside: Bentley ContextCapture can appear to be over-engineered for many drone mapping applications.
Best left to those who already have a certain level of GIS data processing experience or experience of other Bentley packages. Founded inAgisoft has the benefit of existing as an innovative software company both before and during the drone revolution.Yesterday, DroneDeploy announced Volume Measurementsan enhancement to their web-based photogrammetry service that enables rapid volume estimation using only a few clicks of the mouse. At the moment, drone-based volume estimation is commonly used for stockpile monitoring and is one of the few current use cases for drones that has clear ROI benefits.
I get excited about reading announcements, but there is no replacement for actually out new features. I was preparing to fill in a drained swimming pool and had previously done volume calculations using Pix4Dmapper Pro to see how much dirt would be required. I thought doing the same calculation using DroneDeploy would be educational. Some folks might prefer to do volume measurements using the Digital Surface Model DSM view, which is a view that visualizes elevation using color.
Two other photogrammetry apps commonly used with drones, Pix4Dmapper Pro and Agisoft PhotoScanalso support volume measurements. Here is the volume measurement of the same pool volume from the same map data using Pix4D:.
One thing I really like about using Pix4D is that I can interact with my data and annotations. Pix4D reports a volume of DroneDeploy reported a volume of Good data is really important not just for volume measurements, but for photogrammetry in general. Geo-referenced drone data produces maps that are often accurate to just a few centimeters, but adding Ground Control Points GCPs and explicit, known measurements of objects on the ground can increase accuracy dramatically.
Both DroneDeploy and Pix4D estimate the base surface from which volume calculations are done. There might be an explicit way in Pix4D to close the volume to measure complex volumes with a strange base surface, but I would probably map a complex base surface before the materials are placed on it if possible and then subtract the two volumes. You can play with volume measurements for free as part of their day Pro trialand of course, can use their free plan forever for mapping visualizations and sharing.
Pix4D also has a free version of their app called Pix4dmapper Discovery. The best way to educate yourself about photogrammetry is to put your drone in the air and try it yourself. Both DroneDeploy and Pix4D have free versions and offer time-expiring trials of their paid offerings. We live in the future!

Learn About Us.A few weeks ago, DroneDeploy announced the release of our new volume measurement tool, which allows users to instantly calculate accurate volumes on any map. Since then, many people have begun using the tool for a range of applications, including measuring stockpiles and extraction pits.
Dallas started Skymedia Northwest two years ago. With 11 years of experience in the construction industry, and six years as an RC aircraft hobbyist, he saw a big opportunity for drones to bring value to the job site. Dallas flies their production sites to help them monitor inventory of materials, including different types of gravel and recycled asphalt. A ground-based surveyor would measure elevation every 5—10 feet on each pile.
Not only would this take a lot of time and put the surveyor at risk climbing up and down the piles, but this process would also result in relatively few data points, compared to the digital surface area captured by a drone. Just thirty minutes. When he first shows up, Dallas goes through his safety checklist to checks for hazards that might affect his flight, such as power lines, high buildings or trees.
He also notes wind speed and direction. When flying his DJI Phantom 3 Advanced, he plans his mission on the DroneDeploy mobile app and watches as the drone automatically takes off, follows the flight path and lands again.
Once the flight is complete, he takes the SD card out of the drone and puts it into his laptop while still on-site for a quick image quality check. After that, he clicks the volume calculate button and the volume appears instantly. To learn more about how volumes are calculated, check out our support documentation for the volume calculation tool and the elevation toolbox.
Using DroneDeploy, Dallas has been able to achieve accuracy comparable to other tools, in a fraction of the time.
In addition to sharing annotated maps showing volume calculations with his clients, Dallas also likes to share a 3D-model to help support his calculations. Because of the way the volume is calculated, the elevations of the points selected when defining the base of the pile are very important. For example, accidentally selecting a point on a pile of rocks, as opposed to on the ground, will change the volume calculation and its accuracy. To help him get highly accurate calculations, Dallas has a few best practices:.
Use the Elevation View. Here is a volume calculation made while viewing the elevation layer of a map. Areas with the same color have the same elevation. Visually inspect the piles on-site.
Know what a cubic yard looks like.When it comes to 3D photogrammetry software for drones, there is quite a choice. There are many 3D mapping software companies, which provide a free version or free evaluation period, allowing you to try the software first before any purchase. You can then compare the various photogrammetry software packages. Below, we review with videos, the best photogrammetry software for creating 3D maps and models on the market.
To go with 3D mapping software, there are also providers putting together full aerial mapping solutions, which include the drone, mapping software and even training. There are other options to rent professional 3D mapping services, if you feel there is no need to own a drone. Quite a few photogrammetry software companies, also provide hosting in the cloud or data warehousing of your 3D maps and models.
Photogrammetry software can create massive files, depending on the number of images and resolution of the images. The building of 3D maps from images requires a lot of computer processing power and can take ages on an ordinary computer. Many of the below photogrammetry software companies have the systems in place to backup your 3D maps and models, which is very important.
Here are the top 12 photogrammetry software for building 3D maps and models using drones on the market.How to Calculate Stockpile Volumes with Free Software
These photogrammetry software solutions work with both ground based and drone aerial images. Below, we review these 3D photogrammetry software solutions. Towards the end of this photogrammetry software post, we review the best drones for 3D map creation, surveying and geographic information systems work, including 3D mapping companies, which provide solutions to complement the photogrammetry software.
Before we review the best 3D photogrammetry software and solution providers on the market, lets take a quick look at exactly what is 3D mapping. The output from photogrammetry software is typically a 3D map, a 3D drawing or a 3D model of some real world object or land mass. There is an increasing trend to use the term geospatial instead of GIS.
What is the difference between geospatial and GIS? Some people use the terms interchangeably, however, there is a distinct difference between the two. GIS refers more narrowly to the traditional definition of using layers of geographic data to produce spatial analysis and derivative maps.
Geospatial is more broadly use to refer to all technologies and applications of geographic data.
Drone-based Volume Measurement Delivers Big Time-Savings to Mining
The process of utilizing a drone or aircraft to produce aerial photography, which can be turned into a 3D model or mapped digitally. Close range photogrammetry is when images are captured using a handheld camera or with a camera mounted to a tripod. The output of this method is not to create topographic maps, but rather to make 3D models of a smaller object.
To create a 3D model of a monumentstatue or even a face, the camera is mounted horizontally. The drone camera will capture hundreds, even thousands of overlapping photos of the ground, structure or model.
The 3D map or 3D model is then created using aerial image stitching photogrammetry software. The drone will fly using autonomous programmed flight paths called waypoints. It is essential to have a drone, which has waypoint navigation technology. Other fields may be optionally included such as altitude and compass bearing.Fauji love status
Through the use of drone image stitching photogrammetry software and also lidar mapping, there are various products, which can be extracted from the aerial imagery.
These products include. Here are some of the best uses of aerial 3D mapping.
