摘　　要：现有Open CV模板匹配能实现丝印机的定位,但是模版图像不在搜索图中也能得到匹配结果,同时定位执行机构运用传统的直接传值方式运动会造成定位执行机构卡顿。为了解决上述2个问题,提出了一种基于相似度的模板匹配方法。经验证该方法能解决模版图像不在搜索图中也能得到匹配结果的问题,实验结果表明,基于相似度的模版匹配方法对图片的相似度识别都在91%以上,平均用时低于250 ms,具有匹配稳定和快速的特点。同时还提出了一种速度匹配的运动方式,经验证该方法解决了定位执行机构运行卡顿的问题,实验结果表明,速度匹配的运动方式在250次运行过程中没有出现一次卡顿现象。The existing OpenCV template matching can realize the positioning template image can not get the matching result in the search chart, and the of the screen printer, but the positioning actuator uses traditional direct value transfer method causing the positioning actuator stuck. In order to solve the above two problems, this paper proposes a template matching method based on similarity. It is verified that the method can solve the problem that the template image can not get the matching result in the search graph. The experimental results show that the similarity recognition method based on similarity is more than 91%, and the average time is less than 250 ms. A speed-matching movement method has also been proposed. This method solves the problem of the positioning actuator performing the stalling, the experimental results show that the speed-matching movement method does not exhibit a stalling phenomenon during 250 operations.
