The second image shows how the software can be used to calculate the area of the stockpile: In this case, 1,713.33 m. For example, flatter stockpiles will benefit more from a high GSD than taller stockpiles. The first picture shows two key pieces of information: The length of the stockpile (41.46m) and the change in elevation across the stockpile (4.09m from base to middle, and an average of 0.59m across the entire stockpile). Vertically, they lower the uncertainty in Z values, which is proportional to the resolution. Horizontally, high-resolution photogrammetric results create more precise stockpile models, and thus better volume measurement accuracy than ones interpolated from certain measured points. 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. When it comes to stockpile volume measurements, stockpiles do not conform to a perfect shape. Why use photogrammetry for stockpile volume measurements? High-resolution images give you more details of the mapped stockpiles These top mining companies claim that by applying the photogrammetry workflow with Pix4Dmapper, they can achieve measurement accuracies of around 2-5% for their stockpile volumes.

Of the biggest 40 mining companies announced in PWC’s mining report, nearly half of them use Pix4Dmapper photogrammetry software for stockpile measurement and volume comparison as part of their mining workflow.Ĭalculating and 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. Areas for stockpiling soil and material as well as the areas dedicated to parking construction equipment and trucks would be included in the calculation if the. Speed and accuracy: that's the reason why most of the largest mining companies use drones and photogrammetry software in their workflow.
