CAMERA CALIBRATION AND DISTANCE MEASUREMENT BASED ON HOMOGRAPHY

Abstract: example implementations include a method, apparatus and computer-readable medium for estimating a real world height in an image, comprising obtaining a first image and a second image from a camera installed at an unknown height in an environment, wherein the first image includes a first object of known height at a first location and the second image includes the first object at a second location; determining, based on the known object height, a first vector that intersects with a point on the first object in the first image and points to a real world ground plane; determining, based on the known object height, a second vector that intersects with the point on the first object in the second image and points to the real world ground plane; and determining a height of the center of a camera lens of the camera using an intersection of the first and second vector.
