PURPOSE:To detect the deviation between a stop position and a set position stably with high accuracy by performing the digital image analysis of the image signal of a target through a miniature camera provided on the working machine of a cake oven. CONSTITUTION:When a working machine approaches the target 4 of a specified oven by self-travelling and stops, light is radiated to the target 4 from a floodlamp 6. A camera 5 outputs the image signal of the target 4 to an image analyzing device 9 through a cable 10. The device 9 extracts the inputted image signal of the target 4 by digital image analysis and computes the analysis of extraction density in each direction so as to detect two-direction (x-y axes) deviation between a core mark and the image field center of the stop position of the machine 3 and also core dislocation (angle of torsion). These deviation and core dislocation are fed back to a travel control device to make the machine 3 stop into a set position with high accuracy. |
