Abstract

The invention provides a monitoring image correcting method and system. The method comprises the steps that the distance map of a region corresponding to a monitoring image to be corrected is acquired; data classification is carried out on the distance map to acquire a distance map image; and comparison correcting is carried out on the monitoring image to be corrected and the distance map image. According to the embodiment of the invention, the distance map image of the geographical position corresponding to the monitoring image to be corrected is acquired through a preset global digital elevation model database; the monitoring image is corrected by comparing the distance map image and the monitoring image to be corrected; monitoring image correcting can be carried out without a reference substance; magnetic field interference caused by a metal reference substance is eliminated; and the accuracy of monitoring image correcting is ensured.

Description

technical field [0001] The invention relates to the field of electrical data processing, in particular to a method and system for correcting monitoring images. Background technique [0002] In the field of forest fire prevention and field environment monitoring, there are many different intelligent video surveillance systems, such as automatic video detection systems such as forest fire video detection, illegal forest detection and illegal intrusion. The operation of these systems is based on the premise of accurately demarcating the location of the event, but none of these systems can accurately calibrate the location of the event. If there is no accurate system orientation correction, the general monitoring system uses the compass or reference object method to complete the orientation correction. The compass is easily disturbed in an environment with metal structures, inaccurate, and there is a deviation between positive magnetic north and true north. However, in most ou...
