Enter in the T-slot of arc guide rail and with arc guide rail small―gap suture coordinate to be slidably connected, laser level is placed on arc-shaped guide rail
Middle part is simultaneously fixedly connected with T-slot bolt thread, in two targets video camera be individually positioned in arc-shaped guide rail both sides and with it is T-shaped
Slot bolt is screwed connection, and the outer video camera of target is placed on the upper surface of tripod, and bolt is through tripod circular steel plate
Through hole is screwed with the outer video camera of target and is connected.
Casing described in technical scheme is the hollow circular arc part of the one side opening formed by steel plate welding processing, case
The outer surface of body is pasted with geometrical pattern mark.
Arc guide rail described in technical scheme is the circular arc type thin and long units for being machined with T-slot.
Tripod described in technical scheme is process 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 utility model are：
(1) the utility model uses the detection means of binocular active vision, substantially increases the precision of measurement, and laser
The position of level and two video cameras is adjustable, and the visual field is wide, and flexibility ratio is high, simple to operate, saves the time of manipulation.
(2) the utility model is simple in construction, small volume, can apply to various work stations, laser level and takes the photograph
Camera is detachable, is easily installed, repairs, cost is low.
(3) the circular arc type guide rail used in the utility model can realize the position of conversion video camera and projecting apparatus, no
It only ensure that the precision of automobile pattern scanner and the field range of measurement can be ensured.
(4) the utility model carries the position of the casing of gridiron pattern target using the outer camera acquisition of target, and in target
Video camera is only used for gathering the projection striation of level, and avoiding single camera needs not only to gather position but also gather striation and cause
Field range it is narrow the problem of.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings:
Refering to Fig. 1 to Fig. 7, the automobile pattern scanner based on binocular active vision includes casing 1, arc guide rail 2, swashed
The outer video camera 5 of video camera 4, target and tripod 6 in light level 3, target.
Casing 1 is the hollow circular arc part of the one side opening formed by steel plate welding processing, and the outer surface of casing 1 is pasted
There is geometrical pattern mark, arc guide rail 2 is the circular arc type thin and long units for being machined with T-slot, and arc guide rail 2 is placed on casing 1
Inner side is simultaneously welded to connect with the bottom of casing 1, be put at the top of three T-slot bolts in the T-slot of arc guide rail 2 and and circular arc
The small―gap suture of guide rail 2, which coordinates, to be slidably connected, and laser level 3 is placed on the middle part of arc-shaped guide rail and fixed with T-slot bolt thread
