Pole tower monitoring method and terminal based on digital image processing

The invention discloses a tower monitoring method and terminal based on digital image processing, and the method comprises the steps: determining a camera parameter during the shooting of a global camera according to a selected target local object sub-image when a local image is determined after a panoramic image of a monitored tower is determined; the camera parameters are sent to the local camera to shoot a local image which is roughly in the same direction as the global camera and is roughly the same as the global camera, then searching is carried out in the local image based on the contour of the target local object, and the position of the target local object in the local image is determined; and finally, the local camera performs shooting according to the determined position of the target local object and obtains a target image meeting the requirement by comparing with the contour of the target local object, and the target local object is positioned in the panoramic image and the local image in sequence
