Abstract

An on-line measurement system of stone slabs based on CCD technology is constituted by using the CCD camera, image acquisition card, computer and so on. The on-line measurement system for the stone slab is realized by applying camera calibration and image processing algorithms. Under VC++6.0 condition, camera calibration is realized by calling OpenCV1.0 library function and stone slab contour is extracted by using image processing technology. At last, the dimension of the slab can be calculated. The study of this system has great significance in reasonable utilization of stone mine resources, energy conservation and emission reduction.
