Abstract
An analysis method and a measurement system for surveying an elevator shaft of an elevator system wherein the elevator shaft is surveyed by a measurement system having a camera system and an inertial measurement unit having acceleration and angular rate sensors, i.e. designed as an optically inertial measurement system. On the basis of the measured data, a digital model of the elevator shaft is created. Further information on the position of the measurement system in a main extension direction of the elevator shaft, in addition to the information from the acceleration and angular rate sensors of the inertial measurement unit, is recorded and evaluated to create the digital model. In this way, a particularly accurate digital model of the elevator shaft is created.
