System for detecting position of moving vehicle and system for detecting reference points therefor |
摘要 |
A system for detecting reference points to calculate a position of a moving vehicle comprising a means for detecting the azimuth of each light-reflecting means in respect of the moving vehicle on the basis of the reflected light from the light-reflecting means, a means for calculating the current position of the moving vehicle on the basis of the azimuths, a means for calculating the available existence area in which the moving vehicle is predicted to exist at the next azimuth detection time, a means for comparing the position of the moving vehicle calculated on the basis of the detected azimuth at the next azimuth detection time with the available existence area, and a judging means for judging that the detected azimuth is that of the light-reflecting means disposed at the expected reference point if the calculated moving vehicle position is in the available existence area, while the detected azimuth is not that of the light-reflecting means disposed at the expected reference point if the calculated moving vehicle position is not in the available existence area.
