| 摘 要： | 传统的投影变换评价仅考虑精度指标,文中指出投影变换的质量评价指标应包括精度、可靠性、可逆性、惟一性、扩展性和效率.就投影变换的可靠性,以两个平面坐标系间严密坐标变换、平面相似变换和多项式变换模型在不同解算点分布下的实验,考察公共点数量、分布、数据相关性等几何条件,与模型性质对其的影响,验证了可靠性指标的必要性、有效性和可行性,并推导出优化变换抗差本领应具备的要件. |
| 关 键 词： | 投影变换 几何条件 模型性质 可靠性 |

| Abstract: | The traditional quality evaluation of transformation just lies on precision.This paper presents a new series of quality indicators that includes precision,reliability,reversibility,expansibility,uniqueness and efficiency.With experiments of rigorous transformation,plane similitude transformation and polynomial transformation,the affects of geometrical conditions and model's property on robustness are investigated,and the necessity,validity and feasibility of the indicators are confirmed.At last,this paper g... |
| Keywords: | coordinate transformation geometrical condition model's property reliability |
