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 thro

Embodiment 1

[0096] This implementation provides a vehicle-mounted Ethernet automatic parking device and system, see for details Figure 1 to Figure 2 , figure 1 It is a schematic structural diagram of the automatic parking system in this embodiment, figure 2 It is a schematic structural diagram of the parking control module in this embodiment. The automatic parking device and system include: a parking device installed on the vehicle, the parking device includes a central controller, an actuator, a first sensor module, a human-computer interaction module, a second sensor module, and a T-box (Telematics BOX) module, wherein the human-computer interaction module, the first sensor module, and the human-computer interaction module are connected to the central controller through the vehicle Ethernet bus, and the second sensor module and the actuator are connected to the central controller through the CAN bus.

[0097] The central controller is configured to calculate and process the transmi...

Embodiment 2

[0119] The present invention provides an automatic parking method, which includes the following steps: step S1, the parking area is photographed by a plurality of cameras arranged in the parking area and the acquired images are sent to the parking space management system for identification, and the parking lot is obtained Parking space distribution information;

[0120] The image recognition method includes a first parking space recognition method and a second parking space recognition method,

[0121] The parking space image recognition includes a first image recognition method and a second image recognition method, and the intersection of the recognition results of the first image recognition method and the second image recognition method is obtained;

[0122] The intersection is defined as the point set that has the same parking space recognition result in the parking space distribution result obtained by the first image recognition method and the parking space distribution...

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 ...
