为了适应数字化测图的需要,我们进行了将模拟测图仪改造成模拟一数字两用测图系统的实验。本文介绍将TA绘图桌改造成TA-R数字模拟两用绘图桌的情况。TA-R绘图桌已应用于MH-1型数字—模拟两用测图系统,效果令人十分满意。已研制和改造成9套这样的系统,其中6套已运往巴西,承担国际航空摄影测量服务工程的数字测图任务。 In order to meet the needs of digital mapping, we conducted an experiment to transform the analogue gauge into a digital dual-purpose mapping system. This article describes the TA drawing table transformed into TA-R digital analog dual-use graphics desk situation. TA-R drawing table has been applied to MH-1 digital-analog dual-use mapping system, the effect is very satisfactory. Nine such systems have been developed and adapted, of which six have been delivered to Brazil to undertake the digital mapping tasks of the international aerial photogrammetry services project.
