  • Publication number: 20050063565
    Abstract: A vehicle environment monitoring device identifies objects from an image taken by an infrared camera. Object extraction from images is performed in accordance with the state of the environment as determined by measurements extracted from the images as follows: N1 binarized objects are extracted from a single frame. Height of a grayscale objects corresponding to one of the binarized objects are calculated. If a ratio of the number of binarized objects C, where the absolute value of the height difference is less than the predetermined value ?H, to the total number N1 of binarized objects, is greater than a predetermined value X1, the image frame is determined to be rainfall-affected. If the ratio is less than the predetermined value X1, the image frame is determined to be a normal frame. A warning is provided if it is determined that the object is a pedestrian and if a collision is likely.

  • Publication number: 20040183906
    Abstract: 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 in 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. Other 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.

  • Publication number: 20040032971
    Abstract: 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.

    Abstract: 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.

  • Patent number: 6658150
    Abstract: 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.

  • Publication number: 20030091228
    Abstract: An image processing unit determines the size of a circumscribed quadrangle of the target object, and predicts the overlap of the two different objects. Next, 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 the 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.
