Elliptic fisheye image-based distortion correction method

[0033] The correction process of the elliptical fisheye image of the present invention is carried out in three steps, as figure 2 As shown, the implementation process is described in detail as follows:

[0034] 1. Establish an elliptical paraboloid model, and establish a fisheye imaging transformation relationship and a transformation relationship from a fisheye image to a perspective image on the elliptical paraboloid model;

[0035] The establishment process of the elliptic paraboloid model is as follows: image 3 As shown, an elliptical paraboloid is set up in the spatial rectangular coordinate system OXYZ, the origin of the spatial rectangular coordinate system is set as O point, and the elliptical paraboloid is symmetrical about the X axis and the Y axis in the spatial rectangular coordinate system, and the elliptical paraboloid The apex of the vertex is on the positive semi-axis of the Z axis, and the opening faces the negative direction of the Z axis in the space Cart...
