Panoramic system based on monocular camera and working method of panoramic system

Abstract

The invention relates to a panoramic system based on a monocular camera and a working method of the panoramic system. The panoramic system is characterized in that the monocular camera, a single chipmicrocomputer, a PMU power module, a vehicle machine display module and a video synthesis module are included; the monocular camera, the single chip microcomputer, the PMU power module and the vehiclemachine display module are connected with a CPU main control chip in the video synthesis module; the monocular camera is mounted on the rear part of a vehicle, and the single chip microcomputer is connected with a CAN network of the vehicle through a CAN device to obtain vehicle traveling related signals; and the vehicle traveling related signals comprise a vehicle speed signal, a motor rotatingspeed signal, a tire pressure signal, a steering wheel rotating angle signal and a tire diameter signal. Driving safety can be met, the reversing behavior of a diver is reminded and assisted, the moldinput cost of software, hardware and related parts of a reversing video system module can also be reduced, and a panoramic system device can achieve the panoramic effect and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of automobile panoramic image control, and in particular relates to a panoramic system based on a monocular camera and a working method thereof. Background technique [0002] Looking at all kinds of traffic accidents, accidents caused by improper parking are not uncommon. The main reason is that they did not grasp the know-how of safe parking in the surrounding environment due to reasons such as blind spots in vision, improper operation, and inaccurate predictions. Therefore, the reversing image system, as a practical driving assistance system, is of great significance for drivers to avoid accidents and ensure safe parking. [0003] However, the traditional reversing camera system only has a rear-view camera, and there is no relevant display for the left, right and front of the car. When the user is parking in a side position, it cannot display the image of the front of the car. Big trouble, so the panorami...

Problems solved by technology

[0003] However, the traditional reversing camera system only has a rear-view camera, which has no relevant display of the left, right and front of the car. When the user is parking in a side position, it cannot display the image of the front of the car. Big trouble, so the panoramic system came into being

However, the current conventional panoramic image system requires at least 4 cameras to achieve 360° surround view display through image splicing, and the hardware cost is relatively large.

In addition to the software and hardware costs related to the panoramic system itself, the vehicle's front guard and left and right rearview mirrors need to make corresponding structures, and assemble cameras and related wiring harnesses, which will also increase the cost of the entire vehicle.
