Existing structure light vision system adopts two tripods independent of each other to support respectively laser instrument and camera usually, and does adjustment respectively by the shooting angle of its respective tripod to laser instrument crevice projection angle and camera.But the relative position of two tripods independent of each other but cannot be fixed, this causes reliably guaranteeing that in follow-up Constructed Lighting Vision System calibration process linear laser diode and the position of camera remain relative constant.Once laser instrument and the relative position both camera change, by causing the space equation parameter change of acquired system calibrating parameter inefficacy and laser light plane in calibration process, follow-up measuring process cannot be continued on for, needing again again to demarcate.
Utility model content
In order to solve existing employing two tripods independent of each other respectively as the bracing or strutting arrangement to laser instrument and camera, and two tripod attitudes independent of each other are only conducive to the attitude adjustment of laser instrument and camera, but the relative position of reliable guarantee laser instrument and camera in follow-up calibration process cannot remain constant, when causing Constructed Lighting Vision System to be applied, the technical matters that its system calibrating parameter of having demarcated lost efficacy, the utility model provides the combination fastener of laser instrument and camera in a kind of Constructed Lighting Vision System.
The technical scheme that the utility model technical solution problem is taked is as follows:
The combination fastener of laser instrument and camera in Constructed Lighting Vision System, it comprises pedestal, laser instrument attitude-adjusting system, camera angle adjusting mechanism and four screws, pedestal comprises seat board, laser instrument free bearing and camera axle bed, and described laser instrument free bearing and camera axle bed are all fixed on the upper surface of seat board; Described laser instrument attitude-adjusting system comprises laser instrument sleeve, sleeve axle bed, sleeve rotating shaft and bearing pin, and the sidewall in the stage casing of laser instrument sleeve is provided with three fastening screws of laser instrument; The lateral wall of sleeve axle bed top and laser instrument sleeve is connected; Upper end and the sleeve axle bed of sleeve rotating shaft are rotationally connected, and its lower end has radial pin shaft hole; The pin shaft hole of described sleeve rotating shaft lower end is rotationally connected by bearing pin and laser instrument free bearing; Described camera angle adjusting mechanism comprises camera sleeve and camera rotating shaft, and the lateral wall of camera sleeve and one end of camera rotating shaft are connected, and the other end of camera rotating shaft is rotationally connected by camera axle bed and seat board; The sidewall in described camera sleeve stage casing is provided with the fastening screw of camera; Three fastening screws of laser instrument all with described screw mates, the fastening screw of camera and described screw mates.
The beneficial effects of the utility model are: this combination fastener fixes linear laser diode and camera by the laser instrument attitude-adjusting system with two rotary freedoms respectively with the camera angle adjusting mechanism with a rotary freedom, and the relative position of linear laser diode after guaranteeing attitude adjustment by pedestal and camera remains constant, be conducive to reducing Constructed Lighting Vision System in application process, the situation that its system calibrating parameter of having demarcated lost efficacy occurs.In addition, this device also has simple and practical, with low cost, is convenient to advantages such as popularizing.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1 to Figure 2, in Constructed Lighting Vision System of the present utility model, the combination fastener of laser instrument and camera comprises pedestal 1, laser instrument attitude-adjusting system 2, camera angle adjusting mechanism 3 and four screws 4, pedestal 1 comprises seat board 1-1, laser instrument free bearing 1-2 and camera axle bed 1-3, and described laser instrument free bearing 1-2 and camera axle bed 1-3 is all fixed on the upper surface of seat board 1-1.
Described laser instrument attitude-adjusting system 2 comprises laser instrument sleeve 2-1, sleeve axle bed 2-2, sleeve rotating shaft 2-3 and bearing pin 2-4, and the sidewall in the stage casing of laser instrument sleeve 2-1 is provided with three fastening screw 2-1-1 of laser instrument.The lateral wall of sleeve axle bed 2-2 top and laser instrument sleeve 2-1 is connected; Upper end and the sleeve axle bed 2-2 of sleeve rotating shaft 2-3 are rotationally connected, and its lower end has radial pin shaft hole.The pin shaft hole of described sleeve rotating shaft 2-3 lower end is rotationally connected by bearing pin 2-4 and laser instrument free bearing 1-2.
Described camera angle adjusting mechanism 3 comprises camera sleeve 3-1 and camera rotating shaft 3-2, and the lateral wall of camera sleeve 3-1 and one end of camera rotating shaft 3-2 are connected, and the other end of camera rotating shaft 3-2 is rotationally connected by camera axle bed 1-3 and seat board 1-1.The sidewall in described camera sleeve 3-1 stage casing is provided with the fastening screw 3-1-1 of camera.
Three laser instrument fastening screw 2-1-1 all mate with described screw 4, and camera fastening screw 3-1-1 mates with described screw 4.
As shown in Figure 3, in embody rule Constructed Lighting Vision System of the present utility model during the combination fastener of laser instrument and camera, linear laser diode 6 is inserted in laser instrument sleeve 2-1, according to size, the shape rotational alignment laser instrument of workpiece to be detected, to adjust the crevice projection angle of its laser striation on workpiece, after this, linear laser diode 6 is fastened in laser instrument sleeve 2-1 by the fastening screw 2-1-1 of its each self-corresponding laser instrument with three screws 4.In the same way camera 5 is fastened in camera sleeve 3-1.
