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： 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 network system includes a plurality of vehicle-mounted, microcomputer-based electronic devices each having & distributed operating system for performing data communication and distributed processes among the electronic devices. By virtue of the distributed operating system, information resources and hardware resources can be used in common by two or more of the vehicle-mounted electronic devices. Thus the network system has a higher level of network transparency. Because the electronic devices can operate independently and they are interconnected by a common interface called network, a revision to the program of one of the electronic devices or entry of a new electronic device to the network system does not induce tedious and time-consuming version-up of the program of any other electronic device.

摘要： An object detecting system detects an object using an FM-CW wave, so that even if either one of rising-side and falling-side peak frequencies is missing, a plurality of objects can be accurately recognized by accurately combining pluralities of rising-side and falling-side peak frequencies. When it is determined that either one of rising-side and falling-side peak frequencies is missing, the combination of the peak frequencies is determined by calculating the missing peak frequency based on a peak frequency which is not missing.

摘要： There is disclosed an apparatus for displaying a travel path of a running body in which a constantly changing location of the running body on a two-dimensional coordinates is successively computed and the current location of said running body is displayed successively, in accordance with the data thus computed, on a display screen having a map previously displayed thereon. According to this apparatus, longitude and latitude values of a reference point in a mesh consisting of lines of longitude and latitude in each map of divided areas are registered as known factors and the current location of the running body on the two-dimensional coordinates thus computed is converted to a location on longitude-latitude coordinates, whereby the current location on the map is calculated from the known longitude and latitude values of the reference point displayed on the display screen.

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.
