ABSTRACT:
The present invention relates to a method for laser ranging with high precision and high efficient, a method for identifying distance mode automatically during laser ranging process, and a laser ranger with high precision, high efficient and low power waste. The accuracy of ranging is increased through multi classes of receiving process; the accuracy of ranging is further increased through the selection of distance mode and the adjustment of receiving sensitivity before the measuring steps are executed; the accuracy of ranging is further increased through executing jitter judgment on obtained distance measured values to discard the distance measured values that do not satisfy the setting conditions and judge whether the number of remaining distance measured values satisfies the setting quantity requirement; and the present invention is also of simple structure, high measurement efficiency, and low power waste.
