THREE-DIMENSIONAL LOCATION MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional location measuring device capable of obtaining a highly accurate location information system for indoor use to use optical signals as a measuring medium. SOLUTION: This three-dimensional location measuring device comprises a laser beam source 3 to generate optical signals and a reflector to reflect the optical signals and is provided with a device body to utilize the reflected light of the optical signals from object bodies to measure the locations of the bodies and the distances between the bodies and a target 12 with a function to retroreflect the optical signals from the device body and to return them to the device body. In the measuring device, by deflecting and controlling the reflecting plane of the reflector, the direction of irradiation of optical signals are displaced, and the location of the target 12 in a three-dimensional space is detected from the direction of irradiation of optical signals at the point when retroreflection from the target 12 is received and the distance to the target 12 obtained by an optical distance measuring method utilizing reflected light.
