目前,短程红外测距仪已比较普遍地在工程测量中使用。用它代替钢尺或铟钢尺量距已成必然之势,因为它精度高,量距快,受地形条件影响较小,减轻了测量人员的劳动强度。对于这种仪器的检测是很重要的,只有用合理的方法进行检测,方能判断仪器的质量,估计测距精度。本文将以我院使用的一台“DISS”测距仪为例,来探讨对这类测距仪的检测方法和测距精度问题。 At present, short-range infrared range finder has been more commonly used in engineering surveying. Use it instead of steel or indium ruler measuring distance has become an inevitable trend because of its high precision, fast measuring distance, less affected by the terrain conditions, reducing the labor intensity of the surveyors. For the detection of such instruments is very important, only the detection of a reasonable method to be able to judge the quality of the instrument to assess the accuracy of ranging. This article will be used in our hospital, a “DISS” range finder as an example to explore the rangefinder detection methods and ranging accuracy issues.
