Parking route planning method based on vehicle-mounted 3D panoramic look-around

Abstract

The invention discloses a parking route planning method based on vehicle-mounted 3D panoramic look-around. The parking route planning method comprises the following steps of route planning, image acquisition and image splicing and synthesis. The method has the following beneficial effects that cameras are arranged in eight different directions of the vehicle, non-blind area image frames are provided, the imx6 + NVP6324 processor is matched, the image quality can be guaranteed to be clear while the processing capacity of image splicing, correction and the like is improved, and high-definition vehicle look-around panoramic images can be obtained even at night with weak light. Joint calibration and distortion correction are carried out on the spliced panoramic image through the vehicle cornerinformation collected by the corner sensor and the vehicle speed and acceleration information collected by the ADAS, so that a more real vehicle look-around panoramic image is obtained; a 3D panoramic look-around technology is adopted to guide a vehicle parking route to give a driver a more intuitive vehicle surrounding visual influence, and meanwhile, the 3D panoramic look-around technology is matched with an ultrasonic sensor to ensure that collision and other situations do not occur in the vehicle parking process.

Description

technical field [0001] The invention relates to the technical field of automatic parking, in particular to a parking route planning method based on a vehicle-mounted 3D panoramic view. Background technique [0002] Along with the rapid development of the vehicle manufacturing industry, the vehicle electronic technology continues to improve. As two typical applications of artificial intelligence in the field of vehicles, automatic parking technology and 3D panoramic view technology are regarded as two important symbols for the realization of automatic driving. The automatic parking path selection is that the vehicle obtains the parking space status of the parking lot and the location of the vehicle through wireless communication technology, and automatically plans the path for the vehicle to reach the parking space through the computer. 3D panoramic surround view technology uses artificial intelligence, image recognition and other technologies to complete 3D real scene model...

AI Technical Summary

Problems solved by technology

However, the existing automatic parking route selection method can only realize the planning function of the parking route, and cannot judge whether there is an obstacle on the driving route or the parking space. Although the vehicle-mounted ultrasonic or infrared sensor can identify the obstacle around the vehicle, its Due to the limited recognition range, it is impossible to recognize obstacles in all directions without dead ends, and it is also impossible to intuitively display the surrounding conditions of the vehicle from a visual point of view, and the driver may make a wrong judgment when parking.
