METHOD FOR ANALYSIS, AND MEASUREMENT SYSTEM FOR MEASURING AN ELEVATOR SHAFT OF AN ELEVATOR SYSTEM

摘要

The invention relates to a method for analysis and to a measurement system for measuring an elevator shaft of an elevator system. In the method according to the invention, the elevator shaft (15) is measured by means of a measurement system (10) which has a camera system (22) and an inertial measurement unit (25) with acceleration and rotation rate sensors, that is, in the form of an optical inertial measurement system. A digital model of the elevator shaft (15) is created on the basis of the measured data. According to the invention, a further item of information about the position of the measurement system (10) in a main extension direction (16) of the elevator shaft (15) is recorded and evaluated, in addition to the information from the acceleration and rotation rate sensors of the inertial measurement unit (25), in order to create the digital model. A particularly precise digital model of the elevator shaft (15) can be created thereby.
