Automatic parking method

Abstract

The invention provides an automatic parking method. The method comprises the steps: obtaining positions of unoccupied parking spaces in a parking area, controlling a vehicle to park in the parking space according to a calculated parking path; acquiring a parking space image of a parking area by utilizing a plurality of cameras located in the parking area, judging whether a vehicle exists in the parking space or not by recognizing the parking space image, obtaining the parking space distribution of the parking lot, and sending the information of the unoccupied parking space to the vehicle needing to be automatically parked in the parking area; after the vehicle is parked in place according to the calculation path, recognizing and confirming the parking space mark and the license plate number again through the camera. The parking space distribution provided by the invention performs visual identification by using the camera of the parking lot, and compared with the prior art in which a laser radar, a sensor and the like need to be installed in a parking space to identify the parking space, the method provided by the invention has the advantages of low cost, high identification degreeand capability of overcoming the influence of ambient light change on parking space identification.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automatic parking method applied to automobiles. The method involves identifying parking spaces in parking lots and manipulating automobiles to park in spaces. Background technique [0002] In recent years, with the continuous development of the economy and the continuous improvement of people's quality of life, people's demand for cars has increased, resulting in an increase in car ownership year by year. By the end of 2017, the number of private cars in my country had reached 146 million. , accounting for 75% of the total car ownership, an increase of 18% year-on-year. It can be seen that the current volume of private cars is huge, and they are the main means of transportation in the city. The planning of parking spaces in the city has been unable to adapt to the rapid growth of the number of cars, resulting in a huge gap in urban parking spaces. Urban roads are becoming more and ...

Problems solved by technology

This technical defect is very obvious. First, the cost of using lidar is relatively high, and by gradually searching for parking spaces, if the parking spaces are full, the self-searching process of the parking spaces is to gradually search around the road in the parking lot, which is more time-consuming. Time-consuming and labor-intensive and ultimately useless work. In addition, when using ultrasonic radar to identify parking spaces, it can only be identified when there are cars in the parking spaces on both sides of the empty parking space. It is impossible to identify the parking space. In addition, when looking for a parking space through the camera, the image recognition technology is affected by the light, which may also easily lead to inaccurate recognition results.

[0005] In addition, the automatic parking system in the prior art only considers the automatic parking of the own car, but does not consider that when the own car is automatically parked, other cars are also automatically parked near the parking spaces, and many vehicles are automatically parked. When parking, due to the short distance, both parties will think that it is an obstacle and stop and park, so the vehicle cannot be parked.

In severe cases, it may cause a multi-vehicle collision and a safety accident
