Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0024] figure 1 The shown automatic valet parking method includes a surround-view camera installed on the vehicle for capturing image information around the vehicle, a forward-facing camera for capturing image information in front of the vehicle, and a radar for collecting position information of obstacles around the vehicle. and processors that receive and process such information;

[0025] Its valet parking method is as follows: On the one hand, the processor performs pixel histogram and neural network processing on the image information in front of the vehicle acquired by the forward-facing camera, and extracts the part with a pixel value greater than 200 through the pixel histogram processing. The fitted lane line information is fused with the lane line information obtained after neural network processing to obtain the lane line information of the ...

Abstract

The invention discloses an automatic valet parking method, which belongs to the technical field of automobile manufacturing. The method adopts a surround-view camera, a forward-facing camera, a radar and a processor installed on the vehicle; on the one hand, the processor converts the information of the forward-facing camera Carry out pixel histogram and neural network processing respectively, and obtain the lane line information of the vehicle waiting area to determine the vehicle driving boundary and the vehicle surrounding obstacle distribution information to determine the lane keeping; on the other hand, after the processor judges whether the parking space is free Carry out standard parking line feature matching on the surrounding image information of the vehicle. When the matching value of the horizontal parking space is met, the vehicle is controlled to park with the nonlinear constraint trajectory path planning; when the parking space meets the vertical parking space matching value, the vehicle is controlled to park with the key point avoidance path planning. car. The invention can solve the problems of the existing valet parking that the irregular parking causes the parking space to be too large, resulting in poor operating efficiency of the parking lot and low utilization rate of the parking space.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automatic valet parking method. Background technique [0002] With the increase of urban car ownership year by year, the problem of difficult parking is becoming more and more prominent due to the limitation of parking spaces. Therefore, valet parking services are becoming more and more popular. What existing valet parking adopts is the method for semi-automatic parking, promptly the vehicle is driven to the vacant parking space artificially, carries out semi-automatic parking according to the parking information step of vehicle feedback. Therefore, there is a problem that the irregular parking in the parking lot leads to excessively large parking intervals, resulting in poor operating efficiency of the parking lot and low utilization rate of the parking spaces. Contents of the invention [0003] The present invention provides an automatic valet parking met...
