Abstract

To improve the accuracy of outdoor irregular object volume calculation, a signed projection method based on the reference plane is proposed for the determination of the reference plane of the projection method. First, use the Cloth Simulation Filter (CSF) to filter the 3D point cloud model to obtain the ground point cloud; then use the RANSAC algorithm to fit the ground point cloud to obtain the reference plane; secondly, use the signed projection method to calculate the model volume; finally, the true height of the object is calculated by the EPnP algorithm as a scale. In the experimental part, model the iron box and calculate the volume. Comparing the results with the slicing method and the traditional projection method, it is better than other algorithms in terms of accuracy and running time.
