Embodiment Construction
[0042] The following will be combined with Figure 1-5 The present invention is described in further detail.
[0043] Such as figure 1 As shown, this embodiment provides a 3D enhanced panoramic view system for fusion of image and depth information. The 3D enhanced panoramic surround view system includes four fisheye cameras, twelve depth cameras, and a processor.
[0044]Among them, four fisheye cameras and four depth cameras are respectively set in the middle of the front, the middle of the rear and the rearview mirrors on both sides of the vehicle;
[0045] One depth camera is installed on the left and right sides of the front, one depth camera is installed on the left and right sides of the rear, and two depth cameras are installed on the left and right sides of the body;
[0046] Said fish-eye camera: real-time capture of image information around the vehicle with a field of view not less than 180 degrees, the photosensitive component circuit and control component in the...

The invention provides a depth and image information fused 3D enhanced panoramic look-around system, which comprises fisheye cameras, depth cameras and a processor, wherein four fisheye cameras and four depth cameras are respectively arranged in the middle of a vehicle head, in the middle of a vehicle tail and at rearview mirrors on two sides of a vehicle; the left and right sides of the vehiclehead are additionally provided with a depth camera respectively, the left and right sides of the vehicle tail are additionally provided with a depth camera respectively, and the left and right sides of the vehicle body are additionally provided with two depth cameras respectively. According to the system, a target object and the ground are converted into point cloud and unified in a vehicle coordinate system by fusing the depth information and the image information, the situation that the object distortion is large in a common panoramic look-around system is eliminated, the real-time distancebetween the object and the vehicle in the running process can be obtained, and the driving safety and experience feeling are improved.
Description
technical field [0001] The invention belongs to the field of vehicle safety assistance and automotive electronics, and in particular relates to a 3D enhanced panoramic view system based on fusion of depth and image information and an implementation method. Background technique [0002] With the rapid growth of car ownership, road traffic safety has gradually become a major social issue. The panoramic surround view system collects the surrounding environment information of the vehicle in real time through a group of four cameras erected around the vehicle body, and then performs distortion correction and visual transformation processing on the video image information collected by each camera, and then integrates and stitches them into a vehicle and surrounding environment information. The panoramic video is displayed on the center console to assist the driver to operate better during driving, reversing and parking, and reduce the possibility of accidents. [0003] At present...
