如何输出模板匹配结果的中心坐标?
-
clock.tick()
img = sensor.snapshot()# find_template(template, threshold, [roi, step, search]) # ROI: The region of interest tuple (x, y, w, h). # Step: The loop step used (y+=step, x+=step) use a bigger step to make it faster. # Search is either image.SEARCH_EX for exhaustive search or image.SEARCH_DS for diamond search # # Note1: ROI has to be smaller than the image and bigger than the template. # Note2: In diamond search, step and ROI are both ignored. r = img.find_template(template, 0.70, step=4, search=SEARCH_EX) #, roi=(10, 0, 60, 60)) #find_template(template, threshold, [roi, step, search]),threshold中 #的0.7是相似度阈值,roi是进行匹配的区域(左上顶点为(10,0),长80宽60的矩形), #注意roi的大小要比模板图片大,比frambuffer小。 #把匹配到的图像标记出来 if r: img.draw_rectangle(r)

cx = r[0] + r[2]/2,
cy = r[1] + r[3]/2,

可以写一下代码吗
