SURVEYING DEVICE AND SURVEYING DEVICE SYSTEM
Document Type and Number:
Japanese Patent JP2021148533
Kind Code:
A
Abstract:
To provide a surveying device and surveying device system, which can sight an object to be measured at high speed and quickly acquire a narrow angle image of a sighted position.SOLUTION: A surveying device includes: a distance measuring light projecting section 11 for projecting distance measuring light 37; a light receiving section 12 for receiving reflected distance measuring light 38; an optical axis deflection section 26 provided in a common portion of a distance measuring optical axis 39 and a light receiving optical axis 35 for integrally deflecting the distance measuring optical axis and the light receiving optical axis; a projecting direction detection section 19 for detecting an optical axis deflection angle and a deflection direction by the optical axis deflection section; a narrow angle image pickup section 71 with a narrow angle of view having a narrow angle image pickup optical axis which is partially shared with the distance measuring optical axis; a distance measurement arithmetic section 15; and an arithmetic control section 16. The arithmetic control section controls optical axis deflection of the optical axis deflection section and distance measurement operation of the distance measurement arithmetic section, the distance measurement arithmetic section performs distance measurement of a measuring point on the basis of a transmission signal of the distance measuring light and a reception signal of the reflected distance measuring light, and the narrow angle image pickup section acquires a narrow angle image with reference to the distance measuring optical axis, sequentially sights every different object, acquires the narrow angle image, and performs three-dimensional measurement.SELECTED DRAWING: Figure 1
