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 and belongs to the technical field of automobile manufacturing. The method uses a looking-around camera, a forward camera, a radar and a processor mounted on a vehicle. On the one hand, the processor subjects the information of the forward camera to a pixel histogram process and a neural network process, and obtains the lane line information of a vehicle to-be-travelled area for determining the travel boundary of the vehicle and vehicle surrounding obstacle distribution information for determining lane holding. On the other hand, the processor determines whether a parking stall is vacant and then performs standard parking line feature matching on the vehicle surrounding image information, parks the vehicle based on a nonlinear constrained trajectory path plan when the parking stall satisfies a horizontal parking stall matching value; and parks the vehicle based on a key point avoidance path plan when the parking stall satisfiesa vertical parking stall matching value. The method can solve the problem that the nonstandard parking in the traditional valet parking causes a large separation distance and thus results in poor operation efficiency of a parking lot and a low utilization rate of the parking stalls.

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...
