Abstract: PURPOSE:To easily decide the operating abnormality of an unmanned vehicle due to the omission or mislocation of a drive instruction mark by analyzing this mark which is picked up by an image pickup device mounted on the vehicle and comparing the result of said analysis with the mark information stored previously in a memory. CONSTITUTION:A CPU 11 performs the control successively for an image pickup processing action, a recognition processing action, an arithmetic processing action, and a drive processing action respectively. Then the CPU11 controls a CCD camera 3 so that an unmanned vehicle travels straight based on the drive information (straight drive) of a mark 6 of #0 and picks up a mark 6 of #1. The image received from the camera 3 is stored in a work memory 13 and a pattern is recognized. As a result, the drive information on the straight drive is obtained. Based on this information, the information of #1 is read out of a table of a program memory 12 and compared with said drive information. When the coincidence is obtained between both information, the drive of the vehicle is continued. While the information is different from the contents of the memory 12 in case the abnormal drive is decided due to the omission or the mislocation of the mark 6. Thus the abnormal drive is quickly decided.
