Abstract

The invention discloses a target detection method and a related device, and the method comprises the steps: obtaining an original image photographed by a photographing device; performing target detection on the original image to obtain at least one target area; finding out a target area belonging to interference based on the brightness condition in the original image; and eliminating the target area belonging to the interference, and taking the remaining target area as the finally detected target area. According to the scheme, the target detection accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a target detection method and a related device. Background technique [0002] In the process of image and video shooting, there are often business requirements such as tracking and close-up of the target, for example: tracking and shooting a teacher who is presenting a document on the podium, or tracking and close-up of a host who is hosting a program in front of a big screen, etc. [0003] However, in the above-mentioned business scenarios, there may also be graphics similar to the target on the presentation and the large screen, such as human figures, faces, etc. All of these may interfere with normal target detection, making it impossible to successfully complete target tracking and close-up. Therefore, how to eliminate interference and improve the accuracy of target detection has become an urgent problem to be solved. Contents of the invention [0004] T...
