DECIDING METHOD FOR RECOGNIZING POSITION OF OPERATING INFORMATION OF IMAGE TYPE UNMANNED VEHICLE

PURPOSE:To recognize the operating information with high accuracy by omitting the image processes related to the ambiguous picked up images. CONSTITUTION:A CPU 11 carries out successively the control for a mark pick-up processing job, a recognition processing job, an arithmetic processing job, and an operation processing job respectively. These jobs are repeated for drive of an unmanned vehicle A CCD camera 3 undergoes the scan control based on the control signal received from the CPU 11 and then picks up a front area. Then the picture signals of a mark part and a road surface part are binalized into 1 and 0 respectively and stored in a work memory 13. The CPU 11 recognizes the position of a mark 6 based on the picture element data stored in the memory 13. In this case, such marks that are projected ambiguously or incompletely are excluded and only the large and clear marks are recognized. In such a constitution, an image type unmanned vehicle is driven with high accuracy.
