运动侦测,英文翻译为“Motion detection technology”,一般也叫移动检测,常用于无人值守监控录像和自动报警。通过摄像头按照不同帧率采集得到的图像会被CPU按照一定算法进行计算和比较,当画面有变化时,如有人走过,镜头被移动,计算比较结果得出的数字会超过阈值并指示系统能自动作出相应的处理。
cv2.imshow('Harris Corner Detection',image)cv2.waitKey(0)cv2.destroyAllWindows() 在上述示例中,我们首先读取图像文件,并将其转换为灰度图像。然后,使用Sobel算子计算图像的水平和垂直梯度。接下来,根据梯度计算每个像素的二阶矩阵。然后,通过计算响应函数值来确定角点位置,并使用非极大值抑制来抑制非极大值点。
