Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 As shown, the fusion parking system includes 12 ultrasonic sensors 1 (such as: ultrasonic radar), 4 cameras 2 (such as: a 1-megapixel high-definition camera) and 1 fusion controller 3 . The ultrasonic sensor is connected to the fusion controller through a digital signal line, and the camera is connected to the fusion controller through a copper axis; the fusion controller 3 is connected to the vehicle gateway (4) through the CAN bus and Ethernet, so as to realize the control of the vehicle and complete Parking function.

[0022] Such as figure 2 As shown, the detection of the environment by the ultrasonic sensor is direct. During the driving process of the vehicle, the parking system can construct a 2D point cloud environment map through the continuous distance value feedback of the ultrasonic signal, so as to obtain the vertex coordinate informa...

Abstract

The invention discloses a fusion parking system, which comprises a camera, an ultrasonic sensor and a fusion controller, wherein the camera, the ultrasonic sensor and the fusion controller are arranged on a vehicle. The camera acquires camera 3D point cloud information of an obstacle and a parking space in the traveling process of the vehicle through an image mode, the ultrasonic sensor acquires the ultrasonic 2D point cloud information of the obstacle in the traveling process of the vehicle through an echo mode, the parking space information detected by the camera and the ultrasonic sensor isdivided into a non-obstacle and an obstacle, and a distance measurement precision training of the camera and the ultrasonic sensor is carried out on various kinds of information so as to obtain different groups of confidence levels. The sensor information is fused according to different groups of confidence degrees of the sensor, so that an obstacle parking space and a line-marked parking space can be accurately identified.

Description

technical field [0001] The invention belongs to the field of car parking, in particular to a fusion parking system. Background technique [0002] There are many shortcomings in the vehicle parking technology of the prior art. The detection accuracy of the size of the obstacle is very poor for the parking system that only relies on ultrasonic waves, and the size of the obstacle cannot be measured. Parking in lane-line parking spaces; only relying on the 2D image reconstruction technology of the camera to recognize the parking space line function, it cannot identify the distance of all obstacles, and can only recognize and judge the distance of specific types of obstacles. However, the fusion parking technology that integrates ultrasonic sensors only simply superimposes and classifies ultrasonic information and camera information, so that it can be parked in both obstacle parking spaces and marked parking spaces, without improving the parking spaces of ultrasonic sensors or ca...
