Problems solved by technology

[0003] However, the above-mentioned optical ranging principle cannot calculate the surface length of the object to be measured according to the detection light reflected by the object to be measured
Therefore, if it is necessary to know the surface length of the object to be tested, only using this measuring device will inevitably have a certain degree of inconvenience.

Abstract

Embodiments of the present invention provide a measuring device and its operating method, a track sensing system and its track sensing method. The measuring device detects the distance change between the measuring device and an object through a built-in proximity sensor, and judges whether to turn on or off the trajectory sensing module and the optical ranging module, so that the present invention The measuring device can have an intelligent selectable operation function, thereby achieving the advantages of energy saving and power saving, and avoiding the interference caused by unnecessarily turned on sensors.

Description

technical field [0001] The present invention relates to a measuring device and its operating method, and in particular to a measuring device supporting optical distance measurement and track sensing and its operating method. Background technique [0002] In the prior art, a measuring device that only supports the principle of optical distance measurement emits detection light to the object to be measured, and by receiving the detection light reflected from the object to be measured, it is calculated that the light travels between the measuring device and the object to be measured. The time of flight (TOF) of light can be used to calculate the distance between the measuring device and the object to be measured. [0003] However, the above optical distance measuring principle cannot calculate the surface length of the object to be measured according to the detection light reflected by the object to be measured. Therefore, if it is necessary to know the surface length of the o...
