Camera Calibration And 3D-Reconstruction Researchment

The main content of this paper is doing some works about camera calibration 3D_reconstruction metrology and so on . The main tasks is made up of five parts , there are:1: Some discussions about basic concepts of camera calibration and 3D-reconstruction. there are : (A) camera calibration based on linear model ; (B) camera calibration based pin-pole model; (C) Stereoscopic vision and 3D reconstruction of point.2: Some discussions about basic concepts of projective geometry , there are : (A) invariants in the projective transformation ; (B) the relations between affine coordinate and projective coordinate ; (C) the algebrical expression of affine transformation and projective transformation ; (D) the method for expression of point , line in the world , and explaining these .3: putting forward one camera calibration based on a plane pattern octagon method , analysing camera calibration based on affine geometry.4: putting forward one new kind of plane model : making some analysises among several usual models , from their advantages and disadvantages , using the invariants in projective geometry , I put forward new kind of plane model . a lot of simulated photo experiments and real photo experiments provide the availability of this model, finally attaining the metrology based on this plane model.5: putting forward one new kind of camera calibration algorithm based on single Parallelepiped Photo, the simulated experiments provide the availability , finally obtaining the metrology with this algorithm in real photo experiment.
