Document Type and Number:
Japanese Patent JP6406044
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for saving the trouble and time for camera calibration.SOLUTION: A first feature point extracting function part 24 extracts a plurality of feature points of an object person imaged in a first frame image that a first camera 10 captures. A second feature point extracting function part 25 extracts a plurality of feature points of an object person imaged in a second frame image that a second camera 11 captures at a different angle from the first camera 10. A feature point associating function part 26 associates the feature points of the object person that the first feature point extracting function part 24 and the feature points of the object person that the second feature point extracting function part 25 with each other. An external parameter calculating function part 27 calculates external parameters of the first and second cameras associated with relative position relation between the cameras using positions of the feature points of the object person in the first frame image and positions of the feature points of the object person in the second frame image.SELECTED DRAWING: Figure 2
