Embodiment Construction

[0042] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0043] like figure 1 As shown, an embodiment of a radar video composite data detection and processing system is disclosed. The detection and processing system includes: a radar 110 , a video acquisition device 120 , and a radar video information fusion system 130 .

[0044] The radar 110 is used to detect the target and collect target data and environmental coordinates of the target. In this embodiment, the radar 110 adopts the FMCW system with one transmitter and two receivers, and 2D-FFT data processing technology, and the detected target data includes the radial distance, radial velocity and angle information of the target. Through data feature transformation, the radial distance and angle information are converted into the horizontal distance and vertical distance information of the target according to the geometric relationship, and the ...

Abstract

The invention discloses a system and method for detecting and processing composite data of a radar video. The method comprises the following steps: a radar detects a target, and acquires target data and environmental coordinates of the target; after the radar realizes target tracking, video acquisition equipment acquires image information and pixel coordinates of the target; a radar video information fusion system performs information fusion of the target data and the image information of the target; and information fusion includes coordinate conversion, time aligning, data decision and first data association. According to the system and the method disclosed by the invention, fusion of the target data acquired by the radar and image information acquired by the video acquisition equipment is realized through information fusion including coordinate conversion, time aligning, data decision and data association; complementation of advantages of radar data and video data is realized; the stability is high; influence by environment is small; and the anti-interference capability is high.

Description

technical field [0001] The invention relates to an information fusion technology for radar and video composite detection, in particular to a radar video composite data detection and processing system and a detection and processing method Background technique [0002] At present, the existing target detection and classification technologies can be divided into ultrasonic detection, sound detection, infrared detection, magnetic induction detection, laser detection, video detection and microwave radar detection according to their working methods. Among them, video detection is the current mainstream detection method, which has the characteristics of large amount of information and flexible information processing methods, and can obtain more comprehensive information of the detection target, but it is greatly affected by light, shadow and weather. The radar sensor identifies the target by detecting the echo intensity and echo characteristics of the target, and classifies the tar...
