3-D Outline Tracking Intelligence Control Technique and Application-Automobile Outline Parameter Measurement Machine
The technique core of the 3-D outline tracking intelligence control, which adopted in measure automobile outline parameters, lies in the adoption of several photoelectric sensors, laser measuring sensors and super sonic wave measuring sensors to carry on probing, the intelligence control unit makes the photoelectric signal examined as the control basis, and controls the step motor to drive measurement machines and probing sensors to make outline tracking and scans movement along high and breadth direction of the vehicle, and record its outline track, and the data measured is delivered to the computer, finally, acquires the size of the vehicle checked through the place of computer data processing. Then, by comparing with the original vehicle data in the vehicle management database, it makes the adjudicate whether the size of vehicle is within the prescribed limit. System composite: mechanical structure, 3-D intelligence tracking and control unit, data handle computer and intelligence communication between them. The measuring accuracy index is ±0.1% of checked object.
