摘要： The present invention aims at obtaining an in-vehicle processing apparatus for automatically selecting modes. An in-vehicle processing apparatus 120 according to the present invention includes a mode switching unit 121D that makes a transition, based on latitude-longitude positioning information of a vehicle, between: a map storage mode 202 to acquire and store point group data in a storage unit when a vehicle 1 approaches a preset registered spot and point group data of surroundings of the vehicle is not stored in the storage unit 124; and a position estimation mode 203 to have a position estimation unit 121C estimate a position of the vehicle when the vehicle approaches the registered spot and the point group data of surroundings of the vehicle is stored in the storage unit.

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.

摘要： There are provided a calibration apparatus and method capable of obtaining a high-precision calibration result by taking out only feature points on a road surface from images captured by an in-vehicle camera which is a calibration target. A road surface range is estimated by using feature points appearing in an image(s) captured by a camera (a front camera 102 or a rear camera 103) that is not a camera on which the calibration is executed (a side camera 106); and the calibration is executed by using only feature points existing within the estimated road surface range from among the feature points appearing in an image(s) captured by the camera on which the calibration is executed.
