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 information providing apparatus determines and displays the range of presence of a person or other object based on the characteristics of images recorded by infrared cameras. An image processing unit carries out brightness change search processing in the infrared camera image zone represented by a gray scale using a search area wherein the size of a first detected area detected by binarization and correlation operation serves as the reference. In addition, the parallax between the first detected area and the searched area having a change in brightness is compared, a search area having a parallax that differs from that of the first searched area is eliminated, and a search area having a parallax identical to that of the first searched area is provided a highlighted display as an object identical to that of the first detected area.

摘要： A vehicle environment monitoring system for an automotive vehicle is capable of accurately detecting the movement of an object existing in an environment of the vehicle, and determining the possibility of collision between the object and the vehicle, thereby appropriately warning the driver. A relative position of the object to the automotive vehicle is detected from the image obtained by a camera mounted on the vehicle to obtain position data. Positions of the object in a real space are calculated based on a plurality of time series items of the position data detected on the object, and a movement vector of the object is calculated based on the positions in the real space. It is determined based on the movement vector whether or not the object has a high possibility of collision against the automotive vehicle.

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.

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 ECU of a night vision system stores small obtained images of provisional targets as six templates depending on the distance from infrared cameras, and selects one of the templates depending on the distance up to an actual object. Using the selected template, the ECU performs template matching on images obtained by the infrared cameras, and calculates coordinates of the inspection target. The ECU compares the calculated coordinates of the inspection target and stored reference coordinates with each other, and determines mounted angles of the infrared cameras.
