摘要： The luminance signal of a reference image obtained by an infrared camera is adjusted such that the luminance signal of the reference image obtained is greater at all times than the luminance signal of a searching image obtained by an infrared camera. Correlative calculations are performed on the reference image and the searching image to detect one object in the reference image and the searching image without detecting the background of the images in error.

摘要： 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.

摘要： An image information processing system permits stable display of image information regarding an object on an image display device even if an image area of the object recognized through an infrared camera is unstable. In the image information processing system, a first image area recognition unit recognizes a first image area associated with an object on the basis of a second variable based on the position of the object measured through the infrared camera. Further, a second image area recognition unit estimates the first image area on the basis of a first variable and a second variable based on the running mode of an automobile, and recognizes the estimated image area as a second image area. Then, an image information control unit causes a head-up display to display one or both of the first image information associated with the first image area and the second image information associated with the second image area.

摘要： Category determination is performed on an object candidate extracted from a captured image after an exclusion process is performed in advance. In the exclusion process, a distance from a vehicle to the object candidate is calculated based on a size of the object candidate in a current image, a moved distance of the vehicle occurring in a time interval from a time a previous image was captured to a time the current image is captured is calculated, the size of the object candidate in the current image is decreased at a change ratio based on the distance to the object candidate and the moved distance, and a size of the object candidate in the previous image and a size of the object candidate decreased at the change ratio are compared. The object candidate with difference between them being determined to be larger than a predetermined value is removed.

摘要： The vehicle surroundings monitoring apparatus is provided with an imaging device and a device that transforms captured image to digital image. A first edge extraction mask is applied to detect multiple horizontal edges. The apparatus further includes a detector that detects upper end of the head of the object by detecting a horizontal edge having a highest edge intensity out of the multiple horizontal edges. A second edge extraction mask is used to detect the lower end of the head of the physical object by detecting multiple vertical edges and matching the positional variation of the multiple vertical edges with predetermined patterns.

摘要： An imaging means mounted on a vehicle performs imaging resulting in grayscale images having brightness values corresponding to object temperature, and objects around the vehicle are detected from said images. On the basis of said grayscale images, display images to be displayed on a display device mounted on the vehicle are generated and displayed on the display device. The display images are generated by lowering the brightness of areas not corresponding to the objects detected in the grayscale images. The display device is positioned in the vehicle width direction at no more than a prescribed distance away from an imaginary line passing through the center of rotation of the vehicle steering wheel and extending in the longitudinal direction of the vehicle. Accordingly, because display images are generated in which only the objects are spotlighted, the driver can quickly comprehend the objects present when using a display device.
