摘要
为了解决PCB外观检查机中存在的速度问题,对其中用到的形态学运算采用多核并行的方式进行加速。给出了腐蚀运算的普通算法和一种优化算法的多核并行实现过程。实验表明,无论是形态学运算的普通串行算法还是优化算法,通过多核并行处理的方式都可使其运算速度大幅提高。当运算规模较大时,并行加速比可趋近参于运算的处理器数量。
In order to raise the detection speed of PCB visual inspection machine, a multi-core parallel way was used in morphology operation which is necessary in PCB detection. The multi-core parallel implementation process of general algorithm and optimization algorithm for erosion operation was given in this paper. The experiment show that in multi-core parallel way both the general algorithm and optimization algorithm can be greatly improved. When computing scale is large, the speed-up ratio can reach to the number of processors.
