摘　　要：本文对国产正射投影仪的主要技术参数及影响正射像片质量的诸多因素进行了全面的分析与论证，并结合实验数据，提出了既适合我国国情、满足生产要求又追赶国际水平、实现质量控制的关键技术指标，对国产正射投影仪的改进、技术参数的优化、提高产品质量以及正射影像图技术规范的制订具有指导意义。This paper comprehensively analysed and demonstrated the main technical parame- ters of home-made orthoprojector and the factors. which affect the quality of orthophoto. Based on the experimental data. the key technical specifications. which suit the China's conditions. meet the production requirements and catch up with the world standards are presented. It is of instructive importance for the modification of home-made orthoprojec- tor. the optimization of technical specifications. the raising the product quality and draw- ing up the technical specifications for orthophoto map production.
