Camber Angle Inspection for Vehicle Wheel Alignments
This paper introduces an alternative approach to the camber angle measurement for vehicle wheel alignment. Instead of current commercial approaches that apply computation vision techniques, this study aims at realizing a micro-control-unit (MCU)-based camber inspection system with a 3-axis accelerometer. We analyze the precision of the inspection system for the axis misalignments of the acceler...
متن کاملThe Detection System for Angular Deviation of the Train Wheel Billet Based on Laser Ranging Method
This paper presents a detection system for wheel billet end face angular deviation based on laser ranging method. Using three parallel lasers Irradiate the checking surface at the same time, the distance between the wheel billet end face and the laser sensors can be obtained, then the angle between the checking face and the reference plane is calculated by using the geometric theory and the sta...
متن کاملTitle: Aerial Surveillance System for Overhead Power Line Inspection
Electrical companies routinely inspect their overhead lines by helicopter. Current detailed aerial inspection approach uses trained inspectors who fly aboard helicopters to inspect the lines with binoculars and cameras, while recording the data in a logbook. The procedure is performed while the helicopter hovers over and around power lines and structures, creating an element of danger for the p...
متن کاملComputer Vision Based Method and System for Online Measurement of Geometric Parameters of Train Wheel Sets
Train wheel sets must be periodically inspected for possible or actual premature failures and it is very significant to record the wear history for the full life of utilization of wheel sets. This means that an online measuring system could be of great benefit to overall process control. An online non-contact method for measuring a wheel set's geometric parameters based on the opto-electronic m...
متن کاملPrototype Line Crawler for Power Line Inspection
In South Africa, electricity is supplied through thousands-of-kilometers of overhead power cables, which is owned by Eskom the national energy supplier. Currently monitoring of these overhead power cables are done by means of helicopter inspection flights and foot patrols, which are infrequent and expensive. In this paper, the authors present the design of a prototype power line crawler (inspec...
