Information can be obtained through image processing. One of the information that can be obtained is the Volume of a 3-dimensional object. A digital image is 2dimensional data obtained from shooting an object using a camera. A stockpile is a place to store material in an open area. This material is piled up and then taken, processed, marketed, or used later. Various materials can be categorized as a stockpile, one of which is sand material. Calculating the Volume of stockpiles in the mining world is important. Stockpile volume can be measured using image processing. The method used in this research is 3D reconstruction. This image processing uses the Structure from Motion method. The calculation is continued by determining centroid and radius distance using the Euclidean Distance algorithm. The goal of this research is to measure the estimated volume of sand material stockpile based on the results of SFM using Euclidean Distance. Testing experiment processed using a miniature small sand material stockpile. The dataset in this research are images of sand material taken sequentially. Data is obtained using a digital camera. There are nine images used in each test data. The testing data used were 25 pieces of material sand. The average accuracy value is 74.21%, and the RMSE value is 14.31.
