Embodiment 1

[0042] Experimental location: the intersection of Xiangzhang Avenue and Ginkgo Road in Hefei High-tech Development Zone;

[0043] Experimental steps:

[0044] 1), figure 2 The picture on the left is a planar coordinate system drawn in real space. The coordinate origin is the intersection of three thin lines that gradually diverge from bottom to top in the screen. Set four reference points A, B, C, and D in the plane coordinate system, and drag them to the four positions shown in the figure, and obtain the coordinates as follows:

[0045] A: (0.00, 25.00), B: (-0.60, 75.00), C: (6.30, 75.00), D: (6.30, 25.00).

[0046] 2), figure 2 On the right is the real-time video surveillance picture of the real space. The coordinate origin is the lower left corner of the monitoring screen. Similarly, set four reference points A, B, C, and D in the video monitoring screen, and drag the positions shown in the figure respectively. At this point, please ensure that the four reference ...

Abstract

The invention belongs to the technical field of urban traffic and particularly relates to a method for realizing data superposition display based on matrix coordinate conversion. The method comprisessteps that the real-time monitoring information is obtained through radar monitors and monitoring cameras; at least four radar target reference points and video frame reference points corresponding tothe radar target reference points in one-to-one correspondence are set, and a conversion matrix is calculated; coordinate transformation of radar monitoring targets is performed to obtain conversioncoordinates; a vehicle speed label and the vehicle frame information are drawn on a real-time video frame. The method is advantaged in that combination of radar equipment and camera monitoring equipment is realized by matrix coordinate conversion, so problems that a real-time monitoring video does not have the computing function and cannot timely sense the real-time speed and position informationof vehicles can be solved, illegal behaviors of road vehicles can be more visually collected, enforcement difficulty of traffic police is simplified, and strong evidence is provided for verification of the illegal behaviors in the future.

Description

technical field [0001] The invention belongs to the technical field of urban transportation, and in particular relates to a method for realizing data superposition display based on matrix coordinate conversion. Background technique [0002] In the field of urban traffic business, as a widely used monitoring device, the camera can monitor the vehicle traffic at the intersection in real time, and can also provide video recording function with the storage device, so as to facilitate the verification of traffic violations in the future and provide evidence. However, real-time video does not have computing functions. Through the video surveillance screen, we can only see information such as vehicle traffic and congestion on the road, but cannot perceive the real-time speed and location of vehicles in real time, which brings troubles to urban traffic management. . Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the abov...
