The function is used to find initial intrinsic and extrinsic matrices. Homography matrix is determined up to a scale. Thus, it is normalized so that Homography matrix is determined up to a scale. Thus, it is normalized so that h33 = 1. The detection, classification, and location of grid faults have always been challenging for power engineers. Among these, the detection of the grid fault is the most critical task because, without the detection, the remaining two processes will not start. In this study, a fast light-weight fault detection is proposed. This technique uses an empirical mode decomposition to decompose. The intrinsic matrix transforms 3D camera cooordinates to 2D homogeneous image coordinates. This perspective projection is modeled by the ideal pinhole camera, illustrated below. The intrinsic matrix is parameterized by Hartley and Zisserman as. Each intrinsic parameter describes a geometric property of the camera.

Tangential distortion occurs when the lens and the image plane are not parallel. The camera parameters object calculates the tangential distorted location of a point. You can denote the distorted points as ( x distorted , y distorted ), as follows: x distorted = x + [2 * p 1 * x * y + p 2 * ( r 2 + 2 * x 2 )] (3).
