六十年代出现并迅速发展的自动图象分析技术,引起了地质学家和广大地质工作者的注意,并把它应用到岩矿测试中来,使岩矿测试工作逐步摆脱了纯粹手工操作状态,实现了自动测试(或半自动测试)和计算机数据处理。JGT型计算机——光笔式图象分析仪,实质上是一台能直接利用计算机进行数据处理的 The automatic image analysis technology that emerged and developed rapidly in the 1960s attracted the attention of geologists and geologists and applied it to rock and mine tests to gradually remove rock and mine test work from pure manual operation , To achieve automatic test (or semi-automatic test) and computer data processing. JGT type computer - light pen image analyzer, is essentially a direct use of computers for data processing
