Title:
TRAIN CAR POSITION MEASUREMENT DEVICE FOR ELECTRIC RAILWAY MAINTENANCE
Document Type and Number:
WIPO Patent Application WO/2011/136020
Kind Code:
A1
Abstract:
Provided is a train car position measurement device for electric railway maintenance, which is capable of specifying with a high degree of precision the relationship between the traveling position and the transit time of a train car, wherein the train car position measurement device for electric railway maintenance is provided with: a line sensor (1); an image creation unit (10) for using images captured by the line sensor (1) to create a template image and an input image; a memory (12) for saving the template image and the input image created in the image creation unit (10); a template creation processor (13) for extracting SIFT feature values from the saved template image, creating template data, and storing the template data in the memory (12); a SIFT feature value extraction processor (14) for extracting SIFT feature values from the input image and storing said SIFT feature values in the memory (12); and a hangar position detection processor (15) for searching for corresponding points between the SIFT feature values of the template data and the SIFT feature values of the input image that have been saved, detecting a hangar position in the input image, and storing the hangar position in the memory (12).
