Embodiment Construction
[0030] The present invention will be further described below through specific embodiments.
[0031] First, install the fisheye lens in four directions, refer to figure 1 , the four fisheye lenses are respectively installed in the middle of the front, rear, left and right edges of the car roof, the imaging optical axis of the lens is horizontal to the vehicle body, the shooting angles of adjacent lenses differ by 90 degrees, and the imaging angle range of each fisheye lens is 170 degrees. The resolution is 720×576, and the output signal is CVBS analog signal. The four-way analog signal is converted into a digital image by an A / D conversion chip (SAA7111 is used in this example), and then the virtual viewpoint is transformed.
[0032] A kind of driving recorder panoramic video generation method of the present invention, refer to image 3 , including the following steps
[0033] 1) The step of transforming the virtual viewpoint. The four fisheye lenses respectively capture the...
