| 摘 要： | 将明暗恢复形状(SFS)技术应用于表面三维视觉测量。针对传统SFS求解模型的不足,引入一种基于透视投影的反射图模型,并采用高效、简便的灰度梯度算法对该模型进行求解和误差分析。实验结果表明,与正交投影模型相比,透视投影模型的三维表面测量效果显著提高。 |

Realization of 3-D Surface Measurement Based on Perspective Projection Model |
|
| Abstract: | The shade from shading (SFS) technology was applied to the surface 3-D vision measurement. Considering the deficiency of the traditional SFS model, a perspective projection model was introduced and the gray grads arithmetic that is high efficient and simple was adopted to settle the new model and analyze the sources of error. The experimental result shows that the perspective model is quite suitable for the 3-D surface measurement, comparing with the orthographic projection model. |
