摘要：
The present invention is an apparatus which executes a photogrammetry method for calculating soil density. After a user excavates soil, measures the mass of the excavated soil and takes multiple images of the excavation site in combination with a calibration object, a data processor uses the various values obtained from the collected images to create a point cloud data object. The processor used this point cloud data object to create a visual representation of the hole. The processor rotates and scales the visual representation. The processor also uses the point cloud data object in volumetric calculations to determine the volume of the hole. Together with the soil mass, the volume allows calculation of soil density.
