Since Pix4D tech support is slow at responding, does anyone know how to exclude overhead structures from a volume analysis. I have a large stockpile which has conveyor systems overhead - when I perform a volume analysis of the pile under the conveyors, Pix4D assumes the volume includes the overhead conveyor system. Does anyone know how to ‘trim’ a volume to exclude certain areas?
