Abstract

The invention discloses an infrared small target detection method based on a depth map in a complex scene, and belongs to the field of target detection. Through infrared image acquisition, priori knowledge of a to-be-detected target is utilized, a pixel value method is adopted to binarize an image, the binarized image is further limited based on depth priori knowledge, then static and dynamic scoring strategies are formulated, candidate connected regions in the image after morphological processing are scored, and finally, the infrared small target in a complex scene is detected. According to the method, targets in a specific range can be screened out, and the reliability is high; the method has very strong robustness; the method is simple in procedure and easy to implement, can be used insea, land and air, and more highlights the advantages under a complex jungle background.

Description

technical field [0001] The invention belongs to the field of target detection, in particular to an infrared small target detection method based on a depth map in a complex scene. Background technique [0002] In recent years, with the development of military and civilian detectors and infrared thermal imaging technology, target detection based on infrared images has been widely used in unmanned reconnaissance, vehicle obstacle avoidance, battlefield monitoring, and wildlife protection. However, in extremely complex infrared scenes, most target detection algorithms will fail. Due to the small imaging area of ​​infrared small targets, the amount of information carried is small; the heat exchange between the target and the surrounding environment makes the contrast of the target low, lacking information such as shape and texture; the surrounding background often contains interference from objects with similar characteristics to small targets ( Such as branches, walls, etc.) ma...
