Problems solved by technology

[0004]In order to solve the existing false target recognition in specular scenes, the accuracy of specular reflectance estimation is high, the calculation is heavy, and it is only limited to face detection To solve the problem of scope, the present invention provides a false target recognition method, device and computer equipment, which are applied in image target recognition with mirror scenes, and realize the matching and association between real targets and false targets through feature point matching, and have the advantages in practical applications. Better robustness; and the whole method does not involve the process of estimating the reflectivity of the mirror surface, and the whole method has a small amount of calculation, which is not only suitable for the recognition of people, but also suitable for the recognition of objects, and has strong versatility

Abstract

The invention discloses a false target identification method and device and computer equipment, and the method comprises the following steps: obtaining at least one image, each of the at least one image comprising at least one to-be-identified target; when the number of the at least one to-be-identified target is greater than 1, extracting feature points of each to-be-identified target and performing feature point matching; and determining a real target and a false target group from the to-be-identified targets according to the feature point matching condition, wherein the real target and false target group comprises a real target and a corresponding false target. The whole method is small in calculation amount, high in recognition speed, suitable for human recognition and object recognition, and high in universality.

Description

technical field [0001] The invention belongs to the technical field of image recognition processing, and in particular relates to a false target recognition method, device and computer equipment. Background technique [0002] Detecting and analyzing real targets in the scene through target detection technology is of great significance to intelligent monitoring and further analysis of target attributes. In environments with mirrored scenes such as elevators and toilets, the target recognition is different from ordinary scenes. Due to the phenomenon of mirror imaging, when the image is captured through the camera monitoring, the image includes real people or objects, that is, real targets, as well as people or objects in the mirror. Objects are false targets. For the mirror scene, the real and effective complete detection of the target needs to face many challenges, such as target occlusion, deformation, false target and so on. False targets can easily interfere with detecti...
