【摘要】 视点规划在三维物体模型自动测量和重建过程中起很重要的作用。本文通过确定线激光视觉测量系统的可视区域,提出将系统可视区域与模型趋势面相结合的未知模型三维自动重建新方法。依据初始视点下所获模型信息,结合可视区域以及趋势面模型确定出有效视点的空间位置参数,并通过比较这些视点下所获模型的曲面面积,将所获面积最大者的位置定为下一个最优视点的位置。最后,通过实体模型的自动重构,验证方法的可行性及有效性。更多还原

【Abstract】 Automatic reconstruction of 3-D object has attracted much attention both in computer vision and graphics communities. In this paper,a new planning approach of generating 3-D model automatically is proposed.The new algorithm incorporates the visual region of the Laser-vision system with the trend surface of the model and selects the suitability of viewpoints as the NBV on scanning coverage.The candidate NBV position is obtained according to the visual region of the system based on the trend surface model.The candidate that obtains maximum surface area is selected as the next-bestview position.Experimental results show that the method is effective in practical implementation.更多还原
