摘　　要：基于布尔莎空间坐标转换的自检校误差模型,旋转参数的线性化要顾及角度的象限问题,计算过程繁琐且计算量大,而罗德里格矩阵的应用能有效地提高自检校误差模型的效率和精度。本文对新自检校误差模型进行了详细推导,并提出了新模型有效性评定的方法。通过0.5″级全站仪和三维激光扫描仪同步采集数据,分别利用两种模型进行数据处理和对比,确定新自检校误差模型的实用性,验证了基于罗德里格矩阵的自检校误差模型的可行性。Based on the self-checking error model of Burr’s space coordinate transformation,the linearization of the rotation parameters must take into account the quadrant problem of the angle,and the calculation process is cumbersome and large.The application of Rodrigue matrix can effectively improve the efficiency and accuracy of the self-checking error model.In this paper,the new self-checking error model is deduced in detail,and the method for evaluating the effectiveness of the new model is proposed.The data collected synchronously by 0.5″ total station and 3 D laser scanner is processed and contrasted by using two models respectively.The practicability of the new self-checking error model is realized,and the feasibility of the self-checking error model based on Rodrigue matrix is verified.
