摘　　要：结合三角测量原理和视觉激光器的优点,针对地形的纹理映射问题,设计一种基于多点式结构光的三维地形纹理映射系统。系统保持激光器与相机相对位置固定,可以同时采集深度信息及纹理信息,经过图像处理等可以生成具有纹理细节信息的三维虚拟地形,提高纹理映射结果的实时性。其中,系统在深度测量时Z_(w)方向的误差可控制在1.3mm以内,且平台简单,不需要额外相机采集纹理信息,相较于传统的三维测量系统,成本降低,建模效率提高。Combined with the principle of triangulation and the advantages of visual laser,aiming at the problem of terrain texture mapping,a 3Dterrain texture mapping system based on multi-point structured light is designed.The system keeps the relative position of laser and camera fixed,which can collect depth information and texture information at the same time.After image processing,3Dvirtual terrain with texture detail information can be generated,and the real-time performance of texture mapping results can be improved.The direction error of the system in depth measurement can be controlled within 1.3mm.Due to the simple platform,no additional camera is required to collect texture information.Compared with the traditional threedimensional measurement system,the cost is reduced,and the efficiency of modeling is improved.
