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： 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.
