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 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 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.

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.
