Surveying instrument and surveying system

A surveying system comprising:

• a surveying instrument that includes a measuring unit including a tilt sensor configured to acquire tilt angle data of a surveying instrument main body, and an environment sensor configured to acquire environment data having a correlation with a leveling time and leveling accuracy, a leveling unit including a leveling drive unit and configured to level the surveying instrument based on the tilt angle data, an arithmetic control unit configured to control the measuring unit and the leveling unit, and a communication unit that enables communication externally via a communication network;
• a server that includes a server communication unit enabling communication with the surveying instrument, a server storage unit configured to receive measurement data from the surveying instrument and store the measurement data, and a server control unit configured to control the server;
• and
• at least one first external device having the same configuration as the surveying instrument and enabling communication with the server via the communication network, wherein
• the arithmetic control unit includes
• a leveling condition optimization command unit configured to command the server to predict optimum leveling conditions,
• the server control unit includes
• a leveling condition optimization unit configured to predict optimum leveling conditions according to environment data and the surveying instrument-specific information based on results of machine learning of optimum leveling conditions by using the environment data, the leveling result data, the information on leveling operation conditions, and surveying instrument-specific information relating to the surveying instrument and the first external device, stored in the server storage unit, as learning data, and
• the arithmetic control unit includes a program modification unit configured to modify a leveling program so as to realize the optimum leveling conditions.
