Abstract

The invention discloses a moving object three-dimensional size detection system. The moving object three-dimensional size detection system comprises an image obtaining module, a moving object detection module, a moving object coordinate conversion module and an information mapping module. In addition, the invention further discloses a moving object three-dimensional size detection method. The method comprises the steps of image obtaining, moving object detection, moving object coordinate information conversion and information mapping. The moving object three-dimensional size detection system and method provided by the invention are capable of detecting two-dimensional coordinates of a moving object, converting the two-dimensional coordinates into three-dimensional coordinates, further determining the practical size of the object according to the three-dimensional coordinates and obtaining practical special information such as the position, area and speed of the moving object, so that intelligent identification, tracking and behavior analysis of the objects such as persons and vehicles in a video are realized, a more visual and stereo vision effect of a monitored area and the video are realized, the detection precision is improved, and the friendliness and the convenience of the interaction between the user and the system are enhanced.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and relates to a three-dimensional size detection system of a moving target; meanwhile, the invention also relates to a three-dimensional size detection method of a moving target. Background technique [0002] The detection of moving targets by the existing monitoring system can only obtain the two-dimensional information of the target on the projection plane of the camera and the size of the target on the projection plane. The detected target information is actually the two-dimensional information of the target on the projection plane of the camera, not The object itself in three-dimensional space. [0003] Because the two-dimensional information in the camera screen alone cannot determine the actual size of the target, it is impossible to compare and judge with the actual spatial position information. [0004] In order to improve the monitoring accuracy of video surveillance, it is ne...
