Title:
MEASURING APPARATUS
Document Type and Number:
Japanese Patent JP2017106813
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a measuring apparatus that reduces a measurement time.SOLUTION: The measuring apparatus includes: a light emitting element 27, that emits a distance measuring light; a distance measuring light emitting unit 16, that emits the distance measuring light; a light receiving unit 17, that receives a reflected distance measuring light; a light receiving element 33, that receives the reflected distance measuring light and generates a light receiving signal; a distance measuring unit 18, that measures the distance based on the light receiving signal from the light receiving element; a first optical-axis deflection unit, that places on a light emitting optical axis 26 of the distance measuring light and deflects the optical axis of the distance measuring light at a required deflection angle and into a required direction; a second optical-axis deflection unit, that places on a light receiving optical axis 31 and deflects the reflected distance measuring light at the same deflection angle and into the same direction as in the case of the first optical-axis deflection unit; an emitting direction detecting unit 21, that detects the deflection angle and the deflection direction employed by the first optical-axis deflection unit; a control unit 23; and a measuring apparatus body 2, that is supported by a supporting unit to be rotatable in a vertical direction and a horizontal direction and is configured to rotate in a vertical direction and a horizontal direction. The control unit acquires three-dimensional data on a measurement point based on the measurement result obtained by the distance measuring unit and the detection result obtained by the emitting direction detecting unit.SELECTED DRAWING: Figure 2
