Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] refer to figure 1 , The panoramic image generating system of the present invention includes a main control board 2 , a multi-channel camera 1 , a reversing trigger control unit 3 , a control input unit 4 and a vehicle display unit 5 . Camera 1 adopts a wide-angle camera and has at least four channels, which are respectively used to obtain the front, rear, left and right videos of the vehicle body. The reversing trigger control unit 3 is connected with the main control board 2, and generates +12V as a trigger signal for the main control board 2 to work after the automobile is put into reverse gear. The control input unit 4 can be a touch screen or buttons, and is used to interact with the main control board 2. During the forward driving process of the car, the control input unit 4 can also be used to control the main control board 2 to start or stop working. Af...

A panoramic image generating method for assisting driving comprises the following steps: cameras are respectively arranged on all sides of an auto body; the panoramic picture including icons on the auto body and four areas (a front area, a rear area, a left area and a right area) surrounding the icons on the auto body is defined; frame pictures are synchronously extracted from the video stream output by the four cameras through a video acquisition unit; the mapping chart of a world coordinate system-camera image coordinate system is used for calculation, and the synchronously extracted four frames of pictures are mapped to corresponding areas of the panoramic picture to form one frame of panoramic picture; and video coding is performed to the synthetic panoramic picture, the video-coded synthetic panoramic picture is output to a vehicle-mounted display screen, so as to provide a panoramic image within 360 degrees around the auto body for a driver in real time. The method provided by the invention can achieve real non-blind area driving. The generation method of the mapping chart is simple, convenient to operate, and is suitable for commercialization.
Description
technical field [0001] The invention relates to the field of automotive electronics, in particular to a panoramic image generation method for driving assistance. Background technique [0002] Car drivers have many blind spots in the driving process, such as the blocked place in front of the vehicle body, the blind spots of the rearview mirrors on both sides and the blind spots behind the car. The potential dangers of these automobile blind spots often bring great loss of life and property and serious mental injury to people. In addition, with the rapid increase in the number of cars and private cars entering thousands of households, the parking spaces in major cities have become increasingly tight, and the requirements for drivers' parking skills are getting higher and higher. And the existence of the car blind spot has increased the difficulty of parking even more, if you are not careful, you will scratch or collide with adjacent vehicles. Therefore, the problem of blind ...
