Design of dynamic volume measure system based on binocular vision

Based on binocular stereoscopic vision, a dynamic volume measure system was designed. 3 digital Ethernet interface cameras captured images of measured object from different angle, then the images were transmitted to host computer through gigabit network switch. Camera calibration of 3 cameras was carried out by Matlab 2008 and image processing software based on OpenGL carried out smoothing filter, edge extraction and stereo matching for images that captured by cameras. Simulated three-dimensional images were reconstructed based on these images dealing step and the volume of measured object was calculated based on the number of pixels in the simulated three-dimensional images. Measure error of this system was less than 3%; it can be used in many fields.
