## Photogrammetric 3D Reconstruction Based on Known Angle Structured Light

• 摘要: 基于激光经纬仪,介绍了铅垂面扫描方式和圆锥面扫描方式的数学模型,详细推导了角度已知的结构光摄影测量中目标点三维坐标计算的数学模型。使用非量测数码相机,通过试验统计了两种方式下的测量精度,并以人体服装模特为目标,分别重建了服装模特的三维模型,结果证明了基于激光经纬仪的角度已知结构光摄影测量原理的正确性。

Abstract: Two kinds of scanning mathematical models based on structured light with known angle,named scanning mode of plumb plane and scanning mode of circular cone surface,are introduced.If one camera is used to shoot the structured light projected on the object,3D coordinate of point can be obtained after extracting structured light information on the image and calculating point of intersection of photography line and structured light scanning surface.Through the solution of the equations composed of collinearity condition equations and structured light scanning equation,the expressions of 3D coordinates can be inferred simply and clearly.The experimental results prove the correction of photogrammetry theory of structured light with known angle based on laser theodolite.
