Embodiment Construction

[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Please see attached figure 1 Shown, a kind of vehicle-mounted 3D panoramic view display method, comprises the steps:

[0029] Step 1. Collect the spherical images of the front, left front, right front, front left, front right, front rear, left rear and right rear of the vehicle through eight fisheye cameras, and transmit the spherical images to imx6+NVP6324 through the Can bus for processing device;

[0030] Step 2, collect the rotation angle of the vehicle through the rotation angle sensor, obtain the rotation completion information of the vehicle once as the basic parameters of joint calibration and distortion correction, and transmit it to the imx6+NVP6324 processor through the Can bus;

[0031] Step 3. Splicing the repeated parts of the spherical image in eight directions obtained in step 1 through the imx6+NVP6324 processor to obtain a dist...

Abstract

The invention discloses a vehicle-mounted 3D panoramic look-around display method. The method comprises the steps of spherical image acquisition, image splicing, image distortion correction and imagesynthesis. The method has the following beneficial effects: firstly, cameras are configured in eight different directions of a vehicle, non-blind area image frames are provided, an imx6+NVP6324 processor is adopted in a matched manner, the image quality can be guaranteed to be clear while the processing capacities such as image splicing and correction are improved, and high-definition vehicle look-around panoramic images can be obtained even at night with weak light; and secondly, the spliced panoramic image is subjected to joint calibration and distortion correction according to vehicle steering angle information acquired by a steering angle sensor and vehicle speed and acceleration information acquired by an ADAS, so that a more real vehicle look-around panoramic image is obtained.

Description

technical field [0001] The invention relates to the technical field of car surround view, in particular to a vehicle-mounted 3D panoramic view display method. Background technique [0002] With the rapid development of the vehicle manufacturing industry and the continuous improvement of vehicle electronic technology, the car surround view system has emerged as the times require. This technology uses artificial intelligence, image recognition and other technologies to complete 3D real scene modeling, which can help drivers accurately judge the car's own situation and The state around the vehicle can more accurately eliminate the blind spots of the vehicle and avoid many safety problems. In the traditional vehicle surround view system, it mainly uses 4-way standard definition analog cameras, 2D image stitching processing technology and relatively simple control logic. Therefore, there are the following disadvantages: the image quality collected by the traditional car surround...
