Automatic parking-oriented parking space visual identification system and identification method thereof
An automatic parking and visual recognition technology, applied in the traffic control system, traffic control system, character and pattern recognition of road vehicles, etc., can solve the problem that the target parking space cannot be effectively identified, the detection deviation of the target parking space, and the parking position is biased towards the target parking space. It can avoid the detection of redundant straight lines and interference straight lines, improve the robustness, and reduce the false detection rate.

Embodiment 1
[0046] A parking space visual recognition system for automatic parking, such as figure 1 As shown, it includes a parking space image acquisition module, a parking space image recognition processing module, a parking space tracking module and a parking space display module. Each module is described below:
[0047] The parking space image acquisition module transmits the parking space video images collected in the parking lot to the parking space image recognition processing module. Such as figure 2 As shown, the parking space image acquisition module includes two wide-angle cameras, and each wide-angle camera has a base for its matching installation. Each camera can rotate 360 degrees on the base and can adjust its own posture and shooting angle as required. The parking space image acquisition module is installed on the edge of the roof above the B-pillars on both sides of the vehicle as a whole, and is responsible for collecting parking space images in the parking lot.

Embodiment 2
[0052] Based on the above-mentioned parking space visual recognition system for automatic parking, a parking space visual recognition method for automatic parking comprises the following steps:
[0053] Step 1. The parking space image collection module collects the parking space images in the parking lot, and transmits the collected parking space video images to the parking space image recognition processing module.
[0054] Step 2. The parking space image recognition processing module recognizes and processes the received parking space video images frame by frame until a complete parking space is identified in a certain frame of video image, and determines the complete parking space identified in this frame of video image. The location is the target parking space, and the image coordinates of the four corners of the target parking space are passed to the parking space tracking module.
[0055] Such as image 3 As shown, when the parking space image recognition processing mod...
