1. object measures a system, including:

  • First image capturing device and the second image capturing device, in order to capture the image of check point and target piece, wherein, this first image capturing device and this second image capturing device are by non-parallel setting;

    Processing module, connect this first and second image capturing device, the image of this check point in order to capture according to this first and second image capturing device carries out lens correction and object is measured, wherein, the parameter of the image of this check point is substituted into the geometric function based on light beam intersection collinear image formation principle by this processing module, to utilize default algorithm calculate this geometric function and then solve the first camera lens warp parameters of this first image capturing device, second camera lens warp parameters of the first optical center and the first attitude parameter and this second image capturing device, second optical center and the second attitude parameter, to produce should the light beam intersection conllinear function of the first image capturing device and this second image capturing device respectively, make this first image capturing device and this second image capturing device capture the characteristic point coordinate of this target piece more simultaneously, and by this first and this characteristic point coordinate of being captured of this second image capturing device substitute into respectively in this first image capturing device this light beam intersection conllinear function with this second image capturing device to calculate the solid space coordinate of this target piece,First steering mechanism, connects this first image capturing device;

    Second steering mechanism, connects this second image capturing device;

    AndFixed pedestal, connect this first and second steering mechanism, wherein, this first and second steering mechanism is movably set on this fixed pedestal, with the steering angle of this first and second steering mechanism of solid space Coordinate Adjusting according to this check point and/or this target piece, this first and second image capturing device is made to be arranged on this fixed pedestal in nonparallel mode.
