10/6/2023 0 Comments Stockpile measurement calculator![]() This is repeated for every sample that falls within the polygon and the sum of them is the " Calculated Volume". For each 4in x 4in sample we get the elevation and subtract off the dynamic base surface's height to give us that sample's volume. Each pixel in our lookup image has a size of 4in x 4in. Then we determine a dynamic base surface within the defined polygon. This triggers a few different things behind the scenes.įirst, elevation lookup images that were generated at the time of processing are downloaded. Using the Polygon Select Tool (second tool down), the user selects the perimeter of the are area for which they would like to make a volume measurement. This popup explains a bit about how we calculated the volume: The tool is completely web-based and there is no software to buy or download. ![]() These models can be used to measure the volume of dirt stock piles, the amount of dirt removed from a hole or check the flatness of an area. Maps Made Easy allows users to upload images taken from their drone to create high resolution orthophoto maps and 3D models. This calculated value is well within 1% of the hand measured and calculated value. Try it yourself to see how the tool works. This sample was hand measured using RTK to be roughly 10,000 cubic meters. bin file.Precision Volume Measurement in the Web BrowserĪll jobs processed by Maps Made Easy after Februhave the ability to measure 3D volumes. PD: i've tried to attach the cloudcompare file here but it says to me "invalid file extension" to the. If anyone could point me in the right direction for this i would appreciate it so much!!! I will post some photos of the model i'm talking about. I know this must be something i'm doing wrong, i see the potential of this tool and i really want to understand it. The second method is to take that segmented part with the stockpile and set a ground level by myself.Īnyway, the two methods with two different stockpiles it's giving me a volume 20-25% bigger than the real volume. ![]() I set this new raster ground as, exactly, ground level and compute with VOLUME 2.5D between the part cloud and the remaining rasterize cloud. That leave me with a ground that can copy any slope in the terrain. basically after segmentation i take the remaining part (the ground level), rasterize it with interpolation to fill the hole left by the segmentation. The first one is explained in this video. With all this done and checked i've segmented the cloud and tried to learn the volume with two methods. I have modified the scale of this models to match a reference in the scene with known dimensions. I've made photogrammetry models with a very good results in the mesh generated. To make the stockpiles i've used a precision scale a weighted water in a tea cup to know it's exact volume, then i filled up the cup with the materials and spread them in the floor to form the stockpile. I've tried two set ups with different materials. I've seen some similar issues but not exactly an answear to this. I am trying to validate cloudcompare with a homemade experiment for later use in an industrial enviroment.įirst of all i've had searched the forum with the keywords "stockpile volume" and i haven't found the answear to this. I'm new to this world of point clouds! I'm having a big trouble to achieve a volume calculation with the "volume 2.5D" of my stockpile.
