| abstract |
The invention discloses a polarization three-dimensional imaging method capable of characterizing the absolute depth of a target. The initial value of the azimuth angle and the initial value of the incident angle at the point; correct the initial value of the azimuth angle and the initial value of the incident angle; use the corrected azimuth and incident angle to construct a normal vector for each pixel point of the target surface; use the normal vector integral Reconstruct the three-dimensional contour of the target to obtain the surface function of the target; combine the calibration of the camera and the surface function to obtain the absolute depth information of the target. The present invention re-characterizes the target surface normal vector by taking the component of the target surface normal vector along the depth direction as the unit, and the three-dimensional model reconstructed based on the surface normal vector and the absolute depth information of the target have a definite change relationship, breaking the traditional polarization three-dimensional imaging display depth of Relative depth limitations. |
