چکیده
This paper describes an on-going novel vision application to detect abnormal activities in an elevator. Dgference picture technique and human body motion analysis are proposed to accomplish the interpretation tasks. The interpretation makes use of the spatial and temporal features together with the scenario representation. The results obtained are encouraging and further analysis seems fruitful.

An apparatus and method for providing an elevator door performance result of an elevator door in an elevator door system which normally operates sequentially from state-to-state in a closed loop sequential chain of normal operating states is disclosed. A plurality of parameter signals provided by the elevator door system is monitored by the apparatus. The apparatus comprises: a door state seque...
متن کاملPR2 Rides the Elevator
The goal of this project was to design the vision system onboard a PR2 robot tasked with navigating between floors in the ICICS X-Wing at UBC. The vision task includes the detection and localization of elevator buttons that must be pressed in order to ride the elevator to a desired floor. The system is implemented in ROS, the Robotic Operating System from Willow Garage, and executed on the PR2....
متن کاملCondition Monitoring of Rope-less Elevator Braking System Based on Wavelet Denoising
The rope-less elevator driven by Permanent Magnet Linear Synchronous Motor (PMLSM) is a new technology for high-rise buildings. In the practical operation, PMLSM inevitably encounters various kinds of turbulences which directly affect the rope-less elevator’s operation. The braking system is important for rope-less elevator safe and steady operation. Usually, the ordinary inspections are not ab...
متن کاملSemi-Active Control of the Sway Dynamics for Elevator Ropes
In this work we study the problem of rope sway dynamics control for elevator systems. We choose to actuate the system with a semi-active damper mounted on the top of the elevator car. We propose nonlinear controllers based on Lyapunov theory, to actuate the semi-active damper and stabilize the rope sway dynamics. We study the stability of the proposed controllers, and test their performances on...
متن کاملPosition correction of a mobile robot using predictive vision
The path of a mobile robot in indoor environments can be described as a sequence of low level, so called reeexive navigation tasks. Such a task is collision avoidance; a behavior which enables the robot to follow a designated path in environments with large free space areas and to avoid obstacles simultaneously. Keeping up a continuous speed is sometimes more important than always having precis...
