Cylinder target described in technical scheme is the hollow cylindrical part of one end open, the interior welds of cylinder target
There is a block length square plate.
T-slot guide rail described in technical scheme is the thin and long units for being machined with T-slot.
Tripod described in technical scheme is processed by the circular steel plate at top and the elongate rectangular steel plate of bottom
Part, the upper surface center of the circular steel plate of tripod is machined with a manhole.
The beneficial effects of the invention are as follows：
(1) present invention realizes video camera and laser level in target on the premise of the position for ensureing cylinder target is constant
Position it is adjustable, it is ensured that the wide open of automobile morphology detector, and the step of simplify demarcation, greatly save manipulation
Time.
(2) present invention is simple in construction, and video camera and laser level are connected with T-slot guide rail by square head bolt in target
Connect, be easily installed, repair, cost is low.
(3) the two cylinder targets to isotropic are employed in the present invention, the outer video camera of target is in collection cylinder target figure
Do not influenceed during picture by cylinder target posture, substantially increase the precision of demarcation and measurement.
(4) the outer video camera of target is responsible for gathering the image of cylinder target, realizes the outer video camera of target to video camera in target
Coordinate Conversion, the position of video camera and laser level in target is adjustable in target, it is ensured that in detection model greatly
Enclose and interior realize multi-faceted automobile topography scan.
