Abstract

Provided is a three-dimensional data measuring system 1 that enables efficient three-dimensional data measurement without a pole. The system 1 comprises a measuring module 50 including a prism 51, an electronic distance meter 52, an inertial measurement unit 53 configured to detect posture information, a communication unit 58 configured to receive prism position coordinates, and a control arithmetic unit 60 configured to calculate a position of the measuring module 50 based on the prism position coordinates and the posture information to calculate a position coordinates of an irradiated point of the measuring module 50 based on the calculated position of the measuring module 50, a distance to the irradiated point, and the posture information; and a surveying instrument 10 configured to measure a distance to and an angle of the prism 51 to acquire the prism position coordinates and transmit the prism position coordinates to the communication unit 58. When a measurement range exceeds a measurable range where the measuring module 50 performs measurement with a required accuracy without travelling, the system 1 partitions the measurement range into sections in a mesh manner each section having dimensions within the measurement range and sets a measurement route in a guidance data to minimize a travel distance of the measuring module 50, to perform measurement according to the guidance data.
