A method of automatic parking

Abstract

The present invention provides an automatic parking method, which includes obtaining the position of a vacant parking space in a parking area, and controlling the vehicle to park in the parking space according to a calculated parking route, wherein the parking spaces in the parking area are obtained by using multiple cameras located in the parking area Image, through the recognition of the parking space image to determine whether there is a car in the parking space, so as to obtain the distribution of parking spaces in the parking lot, and then send the vacant parking spaces to the vehicles that need to park automatically in the parking area, and the vehicles park according to the calculated path and pass through again The camera recognizes and confirms the parking space mark and the license plate number. The present invention provides the distribution of parking spaces through the use of cameras in the parking lot for visual recognition. Compared with the prior art, it is necessary to install laser radar, sensors, etc. in the parking lot to identify the parking spaces. The technical solution of the present invention has low cost and high recognition degree. , which can overcome the impact of ambient light changes on parking space recognition.

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
