Title: Multiple camera calibration device, method and program
Inventor: KOBAYASHI TATSUYA
IPC: G06T7/80
Filed: 2021-03-30
Abstract: To highly accurately estimate an outside parameter (camera attitude) of all the cameras with respect to a common world coordinate system even under an environment in which a plurality of cameras whose imaging ranges locally overlap with each other exist but a region where all the cameras commonly perform imaging does not exist.SOLUTION: A reference point detection unit 10 detects a marker in which object coordinates are already known from each camera image. A local attitude detection unit 20 detects a local attitude with respect to the marker of each camera on the basis of a correspondence between the object coordinates of the marker and pixel coordinates. A relative attitude detection unit 30 detects a relative attitude between the markers reflected in a camera image for each camera on the basis of the local attitude for each combination of the respective markers. An attitude conversion unit 40 converts the local attitude of each camera into an initial global attitude by using the relative attitude. An attitude optimization unit 50 optimizes the global attitude of each camera on the basis of the initial global attitude of each camera and a re-projection error of each marker.SELECTED DRAWING: Figure 1
