High-speed Image Processing Tech in Optical flexible CMM Based on XC2VP7

光学数码柔性通用坐标测量机的提出是为了满足现代制造对精密测量的要求,它可以实现一般坐标测量机的所有功能,并且易于现场组建,具有通用性;由于目前所采用的数码成像器件具有很高的像素,为了提高系统的测量速度,将Virtex-Ⅱ Pro系列FPGA应用于光学柔性通用坐标测量机中,构建了基于FPGA的高速图像处理的硬件平台,采用外围FPGA结构与嵌入式CPU的软硬件协同工作实现图像的低层次处理算法,加速了图像处理的速度。

With the demand of precise measurements today, the Optical flexible CMM is presented. It can complete all function of the common CMM. Besides it is easy to make up on field and more general. In order to increase the measure rate, the Virtex-Ⅱ Pro FPGA is introduced to optical flexible CMM system. In the FPGA-based high-speed image processing system, low-level image processing algorithm is realized by combining the FPGA frame and the embedded CPU. The velocity of image processing is accelerated due to the introduction of FPGA.
