Embodiment

[0134] Initially, set the initial values ​​for the microwave detector and the video detector: the deflection angle, pitch angle, and tilt angle are all 0; the front and rear, left and right, and up and down displacements are all 0; the horizontal viewing angle is 40, the vertical viewing angle is 22; confirm the video detector The horizontal pixels of the screen are 1920 and the vertical pixels are 1080.

[0135] The debugging process of the message box is:

[0136] The parameters used in the process of adjusting the position of the message box are explained as follows:

[0137] Pitch angle: the up and down pitch angle of the video detector camera (up and down positive);

[0138] Tilt angle: the rotation angle of the video detector screen (clockwise);

[0139] Deflection angle: the horizontal deflection angle of the video detector relative to the microwave detector (left negative and right positive);

[0140] Left and right displacement: the left (-) right (+) distance between the video...

Abstract

The invention discloses a multi-target information fusion and visual presentation method based on microwaves and videos. The method comprises the following process: a microwave detector and a video detector are arranged on a rod and the time of the two detectors is unified; the target coordinates acquired by the microwave detector are mapped into the video image acquired by the video detector; the points mapped to the image are connected to form the information box of the target and the information box is superimposed in the image; the angle, the displacement or the angle of view of the video detector is adjusted until the information box overlaps with the target in the image; and the target information detected by the microwave detector and the video detector is extracted and fused and displayed on the information box. The information superimposition calculation can be performed with test values and then the information box and the target are overlapped through adjustment, and the information is extracted and fused and displayed on the information box so as to realize fusion and visualization of the information and effectively solve the problem that the angle, displacement and other parameters between the microwave detector and the video detector are inconvenient to measure.

Description

Technical field [0001] The invention belongs to the technical field of intelligent traffic management, and specifically relates to a microwave and video-based multi-target information fusion and visual display method. Background technique [0002] With the rapid economic development, my country's automobile industry and per capita car ownership continue to rise, and the consequent road traffic safety issues have become increasingly prominent. In order to ensure the safety and smooth flow of road traffic, people have taken many measures. Microwave detectors have been widely used in the field of intelligent traffic management because of their fast, convenient, non-destructive, accurate and real-time advantages, but microwave detectors cannot do so. When it comes to visual display, the collection of information is limited. For example, microwave detectors can only collect traffic information such as vehicle speed or traffic volume, but cannot collect information such as license plat...
