摘要:
An environment recognition device formed in such a manner that an image sensor (2) is installed so that an image sensor mounting location recognition mark (5) falls within an image pickup area (4), means for comparing mark locations the images of which are picked up sequentially by means of the image sensor (2) with respect to the initial location of the recognition mark (5) in the image pickup area (4) is provided, and, when it is detected that the mark location recognized sequentially has changed with respect to the initial location, an indication signal for indicating that correction of the location of installing the image sensor (2) is required is outputted, thereby to prevent erroneous decision in image processing when the mounting position changes by vibration, contact or the like.

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 is provided a calibration apparatus for calculating a camera installation parameter with respect to a flat surface without preparing two sets of parallel lines on the flat surface, with respect to which the camera installation parameter is to be obtained. An acquirer acquires a photographed image of two linearly-extending lines substantially perpendicular to a flat surface. An extractor extracts the two linearly-extending lines from the acquired image through image processing. A calculator calculates a vanishing point from the extracted two linearly-extending lines and calculates a camera installation parameter with respect to the flat surface on the basis of coordinates of the vanishing point and given coordinates different from the coordinates of the vanishing point.
