摘要
为了研究三角形内定位误差,首先对三角形定位进行建模;其次在对该模型分析证明的基础上得出三角形内最小定位误差出现的条件;最后基于该条件抽象出了三角形内定位误差的变化规律,并通过实际测试验证该规律的正确性.得出的结论均来自于推导计算,为定位算法研究提供了有力理论依据与支持.
A triangle location model is developed to study the location error in triangle. The condition for the formation of minimal location error is found via an analysis of the location model. Then, based on the condition, how the error changes within the triangle is abstracted and its correctness is verified through rome testings. The conclusion is entirely drawn by calculation and it gives theoretically a convincible gist and support for the study on location algorithms.
