Abstract
The invention relates to a method for calibrating a measurement system having at least one image recording apparatus (12) having at least two measurement cameras (31, 32) that form a stereo camera system, and having an analysis unit (13), wherein the measurement system is calibrated by means of a calibration device (22) having reference features (29). The process flow of the method is divided into three steps, wherein in a first step the 3D coordinates of the reference features (29) are determined in a measurement space (30) of the calibration device (22) by at least one image recording camera (9), and in a second step at least one of the image recording apparatuses (12) is disposed in the measurement space (30) of the calibration device (22), and in a third step the 3D coordinates of the at least one image recording apparatus (12) and/or of the at least two measurement cameras (31, 32) are determined in a common 3D coordinate system by means of the analysis unit (13) using the 3D coordinates determined in the first step. The calibration device (22) comprises a measurement space (30) for receiving the image recording apparatus (12) and said measurement space is at least partially b…
