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: A vehicle environment monitoring system for an automotive vehicle, is capable of accurately detecting the movement of an object existing in an external environment of the vehicle, and determining the probability of collision between the object and the vehicle, thereby appropriately warning the driver. A running speed of the vehicle is detected, and a distance between the object and the vehicle is calculated, based on the image obtained by the imaging device. A relative speed between the object and the vehicle is calculated according to the calculated distance. It is determined whether or not there is a significant probability that the vehicle may collide with the object, based on the running speed of the vehicle and the distance therebetween on condition that the relative speed is in the vicinity of the running speed of the vehicle.

摘要: An infrared image-processing apparatus capable of binarization processing in response to the change of the brightness histogram includes an image-processing unit which executes a binarization processing for an infrared image using a threshold brightness value determined in a previous processing, and calculates an area ratio P. When the binarization area ratio P is below a prescribed value &agr; (%), and if the threshold brightness value is not the minimum threshold brightness value Mm_TH, the threshold brightness value ITH is reduced by subtracting a predetermined ratio. Similarly, when the binarization area ratio P is above predetermined value &bgr; (%), and the threshold brightness value is not the maximum threshold brightness value Max_TH, the threshold brightness value is increased by incrementing a prescribed value to the threshold brightness value ITH.

摘要: An image recognition system recognizes correspondence between object images contained respectively in two images obtained by two infrared ray cameras. One of the two images is set to a reference image and another of the two images to a comparison image. A correlation parameter indicative of a correlation between a reference pattern contained in the reference image and containing an object image and each pattern contained in the comparison image and identical in shape to the reference pattern is calculated by using a luminance value indicative of a luminance of the reference pattern and a luminance value indicative of a luminance of the each pattern contained in the comparison image. Based on the calculated correlation parameter, a pattern having a highest correlation with the reference pattern is extracted from the comparison image as a corresponding pattern which corresponds to the reference pattern. Identity between the object image contained in the reference pattern and the object image contained in the corresponding pattern is determined based on a difference between a contrast value indicative of a contrast of the reference pattern and a contrast value indicative of a contrast of the corresponding pattern.
