In order to provide a small, stereo camera with stable errors of distance measurement, there are provided: an image acquisition unit that acquires plural images imaged by plural imaging units; a first region processing unit that divides each of the plural images acquired by the image acquisition unit into first regions composed of predetermined plural pixels, and measures a distance for each of the divided first regions to generate a first distance image; a target object extraction unit that extracts a target object from the distance image or the image, and extracts a second region composed of the plural first regions including the extracted target object; an error factor identification unit that extracts a predetermined representative value from the inside of the second region, compares the brightness value of an arbitrary pixel in the second region with that in a correspondence region up to the position moved from the arbitrary pixel by a disparity represented by the representative value, and determines an error factor on the basis of the comparison result; and a second region processing unit that determines a weight value on the basis of the error factor, and measures a distance for each second region using the weight value to generate a second distance image.

The invention is intended to be able to generate map data even if a location not suited for identification of a matching position exists. A map data creation device creates map data, the map data being used for autonomous movement by a vehicle (), a vehicle () and/or other vehicles (), based on a relative position of the vehicle () which exists around the vehicle (), relative to the vehicle (), the relative position being measured by the vehicle (), and object shape data of an object which exists around the vehicle (), the object shape being measured by the vehicle (). Moreover, the relative position of the vehicle () relative to the vehicle () is calculated based on the object shape data measured by the vehicle ().

A route decision system is provided to avoid an obstacle existing in a traceably moving direction for tracing a reference route from a current location of an autonomous movable body. The system computes traffic distance and a traffic width as a traffic region having a given traffic width and does not allow an obstacle to intrude in each of a plurality of moving The moving direction of the autonomous movable body is decided on the basis of the traceably moving direction and the traffic region. A speed decision device decides a moving speed allowing the autonomous movable body to stop before it collides with the obstacle in response to the braking condition of the autonomous movable body and the location and the speed of the obstacle.

To obtain an image processing device and a method of processing an image that improve distance accuracy and is capable of performing accurate distance even about an object at a greater distance than before, when a distance to an object is measured, one image object regionincluding an image of an object is extracted from one image of a pair of images imaged by a pair of imaging elements at the same time in the same direction. The degree of background that is likelihood of whether either an object image configuration partor a background image configuration partis calculated for each of a plurality of image configuration parts that configures the one image object region. Then, the other image object regionhaving an image similar to the one image object regionis extracted from the other imageusing the degree of background, and a parallax between the one image object regionand the other image object regionis calculated.
