Embodiment Construction
[0028] Such as figure 1 As shown, the present invention sets 5 fixed-focus cameras, and the 4 cameras on the right are on the same horizontal plane, located on the 4 vertices of the same square, corresponding to the four points B, C, D, and E in the figure, and 4 cameras The cameras have the same focal length, set to f s ; The other camera is located on the left of the above four cameras, corresponding to point A in the figure, its axis line is perpendicular to the plane of the four cameras and passes through the center point of the square, corresponding to point O in the figure, and the distance to this point is d , let the focal length of the camera be f t . Initialize the parameters and positions of the five fixed-focus cameras, and their positional relationships satisfy the following constraints: f t =f s +d.
[0029] The working principle and process of the device of the present invention are as follows: five fixed-focus cameras are divided into two groups of full-sc...
