摘要： An apparatus for testing infrared cameras includes: a front plate which has holes arranged in line, and which is adapted to emit an amount of infrared light; and a back plate which is disposed in parallel to and behind the front plate as viewed from infrared cameras to be tested, and which is adapted to emit a different amount of infrared light when compared with the front plate. The back plate is disposed at lower portions of pillars. On the other hand, the front plate is made vertically movable in front of the back plate and along the pillars. By being controlled by a controller, the front plate is movable from the ground height to a level corresponding to approximately two times the height of the back plate.

摘要： The present invention provides an automotive environment monitoring device to detect the existence of an object, a pedestrian or the like, with high accuracy even if one part of the object is overlapped with the background of an image obtained from an imaging unit mounted on the vehicle. An area where the object exists in the image obtained from an infrared camera (102) is set as a first area (A1i) and a lower portion of the first area (A1i) is set as a second area (A2i). A feature of the object is extracted with respect to the second area (A2i) and the object is identified based on the extracted feature. Thereby, even in the case where the first area (A1i) has been set but the feature of an upper part of the object can not be extracted due to the upper part of the object being overlapped with the background of the image, the object can still be identified with high accuracy by extracting the feature of a lower part of the object in the second area (A2i).

摘要： A vehicle environment monitoring device identifies objects from an image taken by an infrared camera. Object extraction from images is performed in accordance with the state of the environment as determined by measurements extracted from the images as follows: N1 binarized objects are extracted from a single frame. Height of a grayscale objects corresponding to one of the binarized objects are calculated. If a ratio of the number of binarized objects C, where the absolute value of the height difference is less than the predetermined value ΔH, to the total number N1 of binarized objects, is greater than a predetermined value X1, the image frame is determined to be rainfall-affected. If the ratio is less than the predetermined value X1, the image frame is determined to be a normal frame. A warning is provided if it is determined that the object is a pedestrian and if a collision is likely.

摘要： A device for monitoring around a vehicle capable of detecting objects present around the vehicle based on an image captured by at least one infrared camera member provided with the vehicle. An area which is inferred to correspond to the pedestrian's head is established as a reference area. Two object areas are established above the reference area so as to correspond to spaces above the shoulders on both sides of the pedestrian's head. An area which corresponds to the head and the shoulders in an infra-red ray image is acknowledged. Another object area which is inferred to correspond to the shoulders and arms of the pedestrian is established. If a distance from an entire pedestrian and a distance from an area which corresponds to the shoulders and arms are equal, it is acknowledged that a binary object including the area which corresponds to the shoulders and arms indicates a pedestrian.
