Resumen
PROBLEM TO BE SOLVED: To obtain a wheel image clearer at higher speed with less distortion by illuminating through a wheel position sensor providing a high resolution artificial visual electronic device, to analyze an image obtained by a camera, processing the measuring value by a computer, and distinctly visualizing is by a monitor. SOLUTION: This device is provided with a wheel position sensor 9 for generating a signal when a wheel is in an ideal position for measurement, a laser generator 5 for projecting plane-shaped laser beams to the wheel at the time of being operated by this signal, and a camera 6 having a lens and a filter for seizing an image generated by the place-shaped beam. A controller 10 illuminates the image with the laser beams through the wheel position sensor 9 synchronizes the image for seizing and seizes it. A high resolution artificial visual electronic device 11 analyzes the image seized by the camera 6 and sends the obtained measured value to a central control computer 8. The measured value is processed in the computer 8 and distinctly visualized by a monitor 13.
