Title: Camera calibration method, program and device
Inventor: KANAME TSUTOMU
IPC: G06T1/00
Filed: 2017-02-23
Abstract: PROBLEM TO BE SOLVED: To accurately calculate a homography matrix from a camera image without requiring complete model matching while using a number of intersections.SOLUTION: A feature vector element generation part 52 generates a feature vector element for each detected intersection. The presence/absence of a field line extending in each direction for each of intersections is allocated to each of bits of the feature vector element consisting of binary data of four bits, and the presence/absence in a "UP" direction is allocated to a most significant bit (MSB1). The presence/absence in a "RIGHT" direction is allocated to an MSB2, the presence/absence in a "DOWN" direction is allocated to an MSB3, and the presence/absence in a "LEFT" direction is allocated to a least significant bit (MSB4). If a field line is present, "1" is set to each of bits and if a field line is absent, "0" is set. A feature vector element at an intersection where a vertical field line in the "UP" direction and a vertical field line in the LEFT" direction are detected becomes "1001".SELECTED DRAWING: Figure 7
