| 摘 要： | 望远镜系统自动调焦功能的实现是摄像经纬仪对目标方位自动精密测量的首要条件.本文针对小视场、恶劣环境以及响应时间短的特定要求,提出了一种基于距离函数的自动调焦方法,根据被测目标的物距通过调用距离函数解算出相应的调焦距离,进而产生位置信号驱动直线步进电机使调焦透镜发生移动,达到调焦的目的.分析表明该方法具有精度高、响应速度...

| Abstract: | Achievement of auto-focusing function in theodolite's telescope system is a primary condition in automatically measuring the angels of the targets.To meet the specific requirement such as small view field,severe environment and short response time,an auto-focusing method based on distance function was presented in the paper.According to the objective distance of target by use of well designed distance function the focusing distance could be calculated and subsequently transformed into locating signal,which ... |
