Abstract
Depth cameras may be placed within an elevator car hoistway to capture depth images of the elevator rope. 3D sensing software may be used to identify the rope within the depth images and assign tracking points to locations along the rope. Tracked images are saved over time and compared to prior tracked images to determine the movement of tracked points between images. Movement of tracked points may be used to determine the velocity, acceleration, frequency of wave motion, and other characteristics of the rope during a period of time. When measured characteristics exceed specified thresholds, the system may take one or more actions to mitigate the undesirable behavior or provide notification of the undesirable behavior.
