DEVICE, METHOD, AND PROGRAM FOR PROCESSING DATA

摘要

PROBLEM TO BE SOLVED: To achieve a configuration capable of performing correction processing of acceleration values precisely without using any tools for correction in a drive recorder.

SOLUTION: A drive recorder body 100 is mounted to a windshield 50 of a vehicle inclined at an angleθ. When the vehicle has stopped on the level ground, an acceleration sensor in the drive recorder body 100 measures an acceleration value x in the x direction and an acceleration value z in the z direction. The drive recorder body 100 uses the measured acceleration value x and acceleration value z and a gravity acceleration value g stored in advance to calculate the mount angleθ, and calculates a correction formula for correcting the acceleration value x in the x direction to an acceleration value in an advance direction of the vehicle and for correcting the acceleration value z in the z direction to an acceleration value in a perpendicular direction on the basis of the calculated mount angleθ.
