摘要
目前,我国的双目光学测距仪器光轴不平行度公差大致有以下几组: 垂直发散:±15′±20′±20′±27′ 水平发散:60′60′60′60′ 水平会聚:20′20′30′36′上述数据基本上是沿袭国外有关数据。美苏两国这方面的数据大致为:
This experiment studied the relationship between the accuracy of rangefinding, visual fatigue and optical axis nonparallelism of binocular opticalrangefinder, in order to provide a basis for setting the standard of verticaldivergence, horizontal divergence and horizontal convergence of binocularoptical rangefinder. A binocular stereo range finding system was used. 10adults with normal vision participated in this experiment under normaltemperature(≈20℃) conditions. The experiment gave the range of limited values and comfortable valuesof the optical axis nonparallelism of binocular optical rangefinder. The limited values are Y=184.22+0.10X-0.19X^2(0≤X≤30) Y=59.54+0.01X-0.06X^2(0≤X≤30) The comfortable values are Y=121.43+0.07X-0.29X^2(0≤X≤20) Y=40.20+0.01X-0.10X^2(0≤X≤20) The results showed that changes of optical axis within certain regions canlead to corresponding changes of accuracy of range finding and visual fatigue
