摘要
大型物体三维形貌数字化测量中,由于传感器单元测量区域小,所以空间图像拼接技术是实现整体测量的关键技术。提出了一种基于移动坐标测量系统实现空间图像拼接的方法,这种方法拼接灵活,适应性强,应用面广,而且可以根据需求进行测量空间扩展。相关试验表明,该拼接方法精度较高,空间距离拼接测量误差小于0.091％。
In the 3D digital measurement of large-scale objects, image mosaic is the key technology to achieve the whole measurement for the small measuring field of sensor unit. The mobile-coordination-measuring-systems-based three-dimensional image mosaic technology is proposed. It has good flexibility and manoeuvrability, and also can expand the measuring space to meet the needs. Through experiments, the method is proven to be with relative high precision on three-dimensional image mosaic and space length measuring error is less than 0.091%.
