    摘要: The present invention provides a camera calibration device and a camera calibration system with which it is possible to execute calibration even in a situation where the load-bearing state of a vehicle changes, and also to precisely estimate all of camera parameters and execute calibration without utilizing the parallelism of the vehicle to, e.g., a white line. The orientation of a vehicle is estimated on the basis of a prescribed feature amount extracted from a video, the translation-direction position of a camera relative to ground is corrected on the basis of information obtained from the calibration executed at a time in the past such as the time of product shipment, and a camera parameter pertaining to the orientation of the camera relative to ground is calculated on the basis of the orientation of the vehicle and the translation-direction position of the camera relative to ground.
