Truck panoramic reversing image system based on 3D vision technology, and using method thereof

Abstract

The invention discloses a truck panoramic reversing image system based on a 3D visual technology, and a using method thereof. The system comprises an image acquisition module, a controller and a userterminal, wherein the image acquisition module comprises two TOF cameras and a binocular camera, the TOF cameras are installed on the left side and the right side of the head of a truck respectively,and the binocular camera is installed at the tail of the truck; and the user terminal includes a display and a speaker. The method comprises the following steps: the image acquisition module acquiresenvironmental depth information around the truck, and the controller reads collected data through Ethernet, performs splicing and other processing, draws a real-time map, calculates a distance betweenthe truck and an obstacle, gives an early warning signal of a corresponding distance segment, and then transmits map information and the early warning signal to the user terminal through a serial port; and the display displays the real-time environment around the truck according to map data transmitted by the controller, and the loudspeaker receives the early warning signal sent by the controllerand sends out a voice prompt. The efficiency and safety of truck parking are improved.

Description

technical field [0001] The invention relates to the technical field of parking assistance, in particular to a truck panoramic reversing image system based on 3D vision technology and a method for using it. Background technique [0002] Limited by its size and length, trucks have a large blind spot when reversing, and it is difficult for truck drivers to judge the situation at the rear of the truck. Therefore, manual guidance is often required when parking trucks, which is inefficient. Moreover, the manual guidance method cannot allow the driver to grasp the environmental information around the truck in a timely manner. When the guide is in a blind spot, safety accidents may occur, so the manual guidance method has a high safety hazard. [0003] 3D vision technology collects the three-dimensional coordinate information of each point in the field of view through the 3D camera, and intelligently obtains three-dimensional imaging through algorithm restoration. This method is not...

AI Technical Summary

Problems solved by technology

However, there are no relevant reports on the application of 3D vision technology to truck reversing and parking. There are still problems with large blind spots and unclear rear vision when parking trucks, requiring manual guidance.
