Title:
VEHICLE-MOUNTED DEVICE, STATION-SIDE DEVICE, AND CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/179892
Kind Code:
A1
Abstract:
This vehicle-mounted device (100) is provided with an original data collection unit (132), a positioning unit (133), and an association unit (134). The original data collection unit (132) causes a laser scanner to collect original section data when a measurement vehicle (10) travels through a calibration section that serves as a section provided on a public road for calibrating laser calibration parameters and has a plurality of surveyed points. The positioning unit (133) generates position information using positioning signals received from positioning satellites by GPS receivers (113A-C). The association unit (134) associates and stores, in a storage device (9140), the position information for the period of the collection of the original section data and the original section data.
