摘要： The luminance signal of a reference image obtained by an infrared camera is adjusted such that the luminance signal of the reference image obtained is greater at all times than the luminance signal of a searching image obtained by an infrared camera. Correlative calculations are performed on the reference image and the searching image to detect one object in the reference image and the searching image without detecting the background of the images in error.

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.

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.

摘要： An image processing unit determines the size of a circumscribed quadrangle of the target object, and predicts the overlap of the two different objects. If overlap is predicted, the target object is divided into two divided regions L_b and R_b containing the left and right edges of the target object respectively, and by performing a correlation calculation between the left image and the right image captured by a stereo camera for each of the divided regions, the parallaxes of the respective divided regions L_b and R_b can be determined. Then, if the absolute value of the difference between the parallaxes of the respective divided regions L_b and R_b is greater than a predetermined value, a determination is made that different objects are overlapping within the target object, and the target object is divided for recognition, and the distance to the respective objects is calculated independently.
摘要翻译：图像处理单元确定目标对象的外接四边形的大小，并且预测两个不同对象的重叠。如果预测重叠，则将目标对象分别分别包含目标对象的左边缘和右边缘的两个分割区域L_b和R_b，并且通过对于每个对象物体执行由立体相机拍摄的左图像和右图像之间的相关计算可以确定各分割区域L_b，R_b的视差。然后，如果各个分割区域L_b和R_b的视差之间的差的绝对值大于预定值，则确定不同对象在目标对象内重叠，并且目标对象被划分以进行识别，并且独立地计算到各个对象的距离。
