摘要： Provided is a device for monitoring the surrounding area of a vehicle. The device separates and extracts an object around the vehicle in better precision from the background. The device detects the ambient temperature of the vehicle, and determines a temperature difference between the ambient temperature and an object surface temperature estimated on the basis of the ambient temperature. On the basis of the brightness value of the background of a captured image obtained by an infrared camera and a brightness difference corresponding to the temperature difference, the brightness value of the object is calculated. The captured image is binarized by using the brightness value of the object as a threshold value, and the object is extracted. Since the binary threshold value is set on the basis of the relation between the ambient temperature and the object surface temperature, the object can be separated and extracted in the better precision from the background.

摘要： Bicycles present before a vehicle are identified. A picked-up image having intensity values that are in accordance with the temperatures of objects is acquired to extract image regions having intensity values representative of higher temperatures than a background. An object, which includes a pair of first object portions (legs) and a second object portion (a tire), would be identified as a bicycle if the pair of first object portions, which have greater dimensions in length in the vertical direction than in width in the horizontal direction and the distance between which is less than a predetermined value in the horizontal direction, are detected from the extracted image regions and further if the second object portion, which has a different intensity value from any one of the first object portions and also has a length greater than a predetermined value in the vertical direction, is existent between the pair of first object portions.

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： An image analysis device installed on a vehicle for detecting objects that are likely to affect the vehicle. An image processing unit included in the image analysis device sets a seeking area in a left-hand image of the field, and calculates a moving increment for seeking “Step” using a variable “n”. A correlation calculation process is sequentially executed in the seeking area set in the left-hand image of the field while moving a reference image stepwise at the moving increment “Step” so as to obtain a correlation area that gives the highest degree of correlation, and then a new seeking area is set, which consists of the correlation area and horizontally arranged two areas that sandwich the correlation area, and the moving increment “Step” is decreased in order to reduce the amount of calculation.
