The invention relates to the technical field of automatic parking, provides a parking method based on parking space calibration, and designs a novel preset splicing strategy to improve the splicing efficiency of panoramic images in order to improve the automatic parking efficiency. At the beginning of parking, a parking coordinate system is established, a position relation function of an initial parking space and a vehicle is determined, a parking route is planned, and the position of the initial parking space in a current panoramic image can be judged in real time by using the position relation function (the initial parking space is mapped to the current panoramic image), so that in one image, whether the position of the target parking space is consistent with the actual position of the target parking space at the current moment during previous parking path planning is determined, the initial parking space is corrected under the assistance of a preset correction strategy to obtain a corrected parking space, and a parking path is replanned. Error calibration is carried out on the parking space, so that the accuracy of wired parking space identification is improved, and the parking success rate of the wired parking space is improved.
Description
technical field [0001] The invention relates to the technical field of automatic parking, in particular to a parking method based on parking space calibration. Background technique [0002] Automatic parking replaces manual parking, reducing the difficulty of parking. Different automated parking systems use different methods to detect objects around the car. Some have sensors around the front and rear bumpers that act as both transmitters and receivers. These sensors send signals that bounce off obstacles around the vehicle. At this point, the on-board computer uses the time it takes to receive the signal to determine the location of the obstacle. Other systems use bumper-mounted cameras or radar to detect obstacles. But the end result is always the same: The car detects parked vehicles, the size of the space, and the distance to the curb, and steers into the space. [0003] However, there will be a deviation (10cm-30cm) between the position of the parking space identif...
