Patent attributes
The present invention provides an image processing method for a vision system. The vision system includes a central processor, at least two camera groups a sensor for obtaining a rotation angle signal of each of the camera groups. The camera groups each includes at least one camera and is configured to capture an image and send it to the central processor. The sensor is configured to send the obtained rotation angle signal to the central processor. Wherein during a conjugate rotation of two of the camera groups about respective optical axes thereof, the central processor is configured to perform rotation angle compensation on images based on an angle of rotation of the camera groups. The present invention solves the problem of unclear images captured by a camera that is rotating about its own optical axis in response to the rotation of a target object or scene. In particular, it solves the problem of vertical offsets between images captured by two camera groups that are rotating about their own optical axes conjugately for a certain reason, for example, when they are tracking a target object.
