Abstract (en)
[origin: EP1232988A1] The shaft information generation method uses visually detectable patterns provided along the elevator shaft, provided by structured surfaces of shaft components having a different function. Images are generated by stepped detection of the patterns, the image data fed to a correlator providing an estimated position from the incremental position of a new image and the absolute position of a preceding image and fed to a second correlator providing an absolute position for the lift control.
