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: 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. The device includes a binary object extraction unit which subjects a gray scale image of the image captured by the infrared camera member to a binary thresholding method, and extracts a binary object from the gray scale image; a gray scale object extraction unit which extracts a gray scale object, a range of the gray scale object including the binary object, from the gray scale image based on change in luminance of the gray scale image, and a pedestrian determination unit which sets a search area in an area including the gray scale object, and recognizes a pedestrian in the gray scale image based on a luminance variance in the search area.

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.

摘要: Two aiming targets are arranged at positions that are away from two infrared cameras by a predetermined distance. One of the infrared cameras images one of the aiming targets, and the other of the infrared cameras images the other of the aiming targets. Assuming that the obtained images relate to an image of one aiming target, a parallax offset value is calculated. The correction of position is performed based on the parallax offset value.

摘要: A first object and a second object arranged in an actual space with coordinates (Xn, Zn) and (Xn−D, Zn) are imaged, and respective coordinates x1* and x2* of the first object and the second object in the image are calculated. Then, a coordinate x1 of the first object in the image and a coordinate x2 of the second object in the image are calculated by equations: x1=F·Xn/Zn x2=F·(Xn−D)/Zn where F is a design parameter of an imaging unit. An image distortion corrective value α to correct the design parameter F is calculated by equations: α·x1*=x1 α·x2*=x2 using a difference between the coordinates x1 and x1* and a difference between the coordinates x2 and x2*.

摘要: A right infrared camera produces a right gray-scale image by imaging aiming targets disposed in a right position, and a left infrared camera produces a left gray-scale image by imaging aiming targets disposed in a left position. An average value of coordinates of the aiming targets in a preset clipping area is determined, and an average value of coordinates of the aiming targets in a preset clipping area is determined. A difference between the average value and the average value is determined, and the clipping area is moved depending on the difference.
