摘要： Disclosed is a travel path displaying apparatus for indicating the current position of an automobile running on a selected road in a road map appearing on an associated screen. A cumulation of errors in estimating sequential current positions will cause an incorrect indication of the automobile's position on the screen and the automobile will depart from all the roads appearing on the screen. In order to find the correct road on which the automobile is traveling it is necessary to carry out pattern matching between the travel trace and each of a number of selected roads, thereby determining which road is closest to the travel trace in shape. The apparatus permits selection of the least possible number of roads for pattern matching, thus permitting quick determination as to the road on which the automobile is traveling and as to the direction in which it is traveling.

摘要： An apparatus for displaying a travel path of a running body in which a direction detector includes a geomagnetism sensor as well as a rate-type sensor, such as a gyroscope or gas rate sensor (which includes a flow sensor for detecting a degree of displacement of a gas flow produced by an angular velocity applied thereto) for detecting an angular volocity of change of yawing direction of the moving body, in which a difference in angle between directions detected by the rate-type sensor and the geomagnetism sensor is found and temporarily stored when a power source is temporarily turned OFF during operation of the running path displaying apparatus, and then a declination of the direction detected by the geomagnetism sensor is corrected, depending upon the stored difference in angle, when the power source is turned ON again.

摘要： A multibeam radar system. A matrix or inverse matrix indicating the characteristics of beams of ultrasonic waves or radio waves are previously created for each individual scanning direction (channel) and stored in a memory. Physical quantities corresponding to the intensities of echo signals and to the distance to an object are detected, and temporarily stored in another memory together with the corresponding scanning directions. Those of the temporarily stored data items which represent physical quantities corresponding to the same distance are arranged in rows or columns corresponding to the scanning directions. Inverse calculation processing, or deconvolution processing, is performed according to the matrix or inverse matrix indicating the beam characteristics. In this way, the reception level is corrected.

摘要： A three-dimensional-object can be effectively detected. A pair of image capture devices capture a three-dimensional-object and calculate disparity component data of subdivided-image regions, respectively. On a basis of the disparity component data, gray scale values indicative of distances from the image capture device are calculated and a gray scale image in which each region has its corresponding gray scale value is generated. A model of the three-dimensional-object is defined and correlation values is calculated to show the degree of a similarity between the model and the image subdivided regions in the gray scale image. The model is a two-dimensional image with a shaping characteristic when the three-dimensional object is viewed from positions of the image capture devices while each subdivided region of the two-dimensional image has a gray scale value indicative of a distance from the image capture device at a portion corresponding to the three-dimensional object. The correlation values are calculated on a basis of gray scale values of the model and those of the image region in the gray scale image. The model and an image region with the highest correlation value are detected in the gray scale image, so that a three-dimensional image is detected.

摘要： A vehicle control system for controlling its own vehicle to follow another vehicle in pursuit has a radar unit. The radar unit has function for detecting a relative distance from its own vehicle to a front vehicle in front of its own vehicle and a relative speed of the front vehicle with respect to its own vehicle, and outputting information representing the relative distance and the relative speed. A lane change detector detects a lane change which is made by its own vehicle and outputs a lane change signal indicative of the lane change. A processor estimates a future lane or path for its own vehicle from the lane change signal from the lane change detector, unlocks a preceding vehicle which its own vehicle has followed, and determines a new preceding vehicle which its own vehicle is to lock on based on the estimated future lane or path and the information outputted by the radar unit.
