The present invention provides an intelligent parking space recognition method and device, and a car. The method includes the following steps: acquiring a wide-angle image and a depth image of the environment on one side of the vehicle during the process of searching for a parking space; determining whether there is a suspected line parking spaces, determine whether there are suspected space parking spaces and suspected obstacles according to the depth image; if there are suspected line parking spaces and suspected space parking spaces, then calculate the size of the suspected line parking spaces and the suspected space parking spaces, Size determines whether the suspected line parking space is an available line parking space, and determines whether the suspected line parking space is an available space parking space according to the size of the suspected space parking space; if there is a suspected obstacle and an available space parking space, then judge the suspected obstacle Whether the object is located in the parking space in the available space; finally, the available parking space is judged in combination with the results of the previous steps. The invention can improve the detection ability of obstacles in the parking space and the identification rate of effective parking spaces.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to an intelligent parking space identification method and device, and an automobile. Background technique [0002] A key technology of smart parking is to realize the identification of parking spaces through the addition of long-distance ultrasonic sensors and cameras installed on both sides of the vehicle, which provides the primary conditions for smart parking. The current long-distance ultrasonic sensor recognition method and camera recognition method can recognize standard parking spaces in a good environment. However, in some special environments, some parking spaces still cannot be recognized or are misrecognized. [0003] For example figure 1 In the special environment shown, the parking space identified by the existing method has a misjudgment. In this environment without parking space lines, the size of the orange obstacle in the picture is smaller than the jump th...
