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 carries out camera calibration and solves transition matrix using cube target, due to cube target
It is more relative to the information that two-dimensional target and 1-dimension drone are carried to substantially increase the precision demarcated with measurement, and cube
Target is easily worked, and also greatlys save the pre-production time.
(2) simple structure of the present invention, video camera and laser level are consolidated by square head bolt with T-slot guide rail in target
It is fixed, it is easily installed, repairs, low cost.
(3) in the present invention in target video camera and level distance variable, substantially increase regarding for video camera in target
The scanning area of field scope and laser level, and may be implemented in change on the premise of the position for not changing cube target
Video camera and the relative position of laser level, simplify operating procedure in target.
(4) the outer video camera of target in the scan-type automobile morphology detector based on cube posture benchmark of baseline distance is become
It is responsible for the image of collection cube target, realizes the demarcation of the outer video camera of target and by the outer video camera of target to video camera in target
Coordinate Conversion, video camera is responsible for gathering the intersection image on laser level and body of a motor car surface in target, shooting in target
The position of machine and laser level in target is adjustable, it is possible to achieve automobile topography scan multi-faceted on a large scale.
