CAMERA CALIBRATION

摘要

First and second angles are measured from a nominal camera centerline to respective first and second positions. The first position is determined by the camera locating a first centerpoint in a first board. The second position is determined by the camera locating a second centerpoint in a second board. The first and second angles, and first and second horizontal distances of the camera from the first board and the second board, respectively, are used to obtain a determined vertical distance and a determined angle. The determined vertical distance measures a distance from the second centerpoint to a point determined by an intersection of a first line through the second board and a second line that is parallel to the floor and has an endpoint at the camera. The determined angle measures an angle of between third line extending from the camera in the nominal position and the second line.

主权项

1. A computing device comprising a processor and a memory, wherein the computing device is programmed to:
store in the memory a first horizontal distance of a camera from a first board and a second horizontal distance of the camera from a second board; receive first and second angles from a nominal camera centerline to respective first and second positions, the first position being determined by locating a first centerpoint in the first board with the camera, and the second position being determined by locating a second centerpoint in a second board with the camera; and use the first and second angles, and first and second horizontal distances of the camera from the first board and the second board, respectively, to determine
a vertical distance from the second centerpoint to a point determined by an intersection of a first line through the second board and a second line that is parallel to the floor and has an endpoint at the camera, anda misalignment angle between a third line extending from the camera in the nominal position and the second line.
