Abstract: A remote communication system includes a portable device; and a fixed system. The fixed system includes main communication modules; and a position estimating unit configured to estimate a position of the portable device, based on an incident angle of a signal from the portable device, upon detecting the signal by antennas provided in the main communication modules. When there are two main communication modules for which the incident angle is known, the position of the portable device is estimated based on the incident angle. When there is one main communication module for which the incident angle is known, the position of the portable device is estimated based on the incident angle and a received radio wave intensity of the signal. When there is no main communication module for which the incident angle is known, the position of the portable device is estimated based on the received radio wave intensity.

Abstract: An image processing apparatus comprises an inputting section for inputting a plurality of continuous images which were photographed by a photographing section progressively moving relative to a photographed object; an extracting section for extracting characteristic points from images input by the inputting section; a tracking section for tracking the points corresponding to the characteristic points in the plurality of continuous images; an embedding section for embedding tracking data, which includes data of extracted and tracked points by the extracting section and the tracking section, into each image; and an outputting section for outputting the plurality of continuous images sequentially in which the tracking data was embedded by the embedding section.

Abstract: This invention provides a three-dimensional measurement system that improves the efficiency of and enables the automation of non-contact three-dimensional measurement over a wide range using a coded target. A measuring object 1 is photographed in stereo such that the resulting images include four coded marks CT each having a position detection pattern P1 and a code pattern P3. A series of images are photographed in stereo such that adjacent images share two coded marks CT. The position detection pattern P1 and the code pattern P3 are extracted from a pair of photographed images. A point corresponding to a reference point is searched for using the identification codes of the coded marks CT. A stereo matching area is determined. All the processes including photographing, extraction, orientation and three-dimensional measurement can be fully automated.
