Environment recognition device provided with image pickup device

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.
