PITCH ANGLE DETECTION DEVICE AND PITCH ANGLE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pitch angle detection device capable of detecting a pitch angle of a vehicle even in the case where a peripheral object (traffic lane or the like) for detecting the pitch angle does not exist, and further to provide a pitch angle detection method.;SOLUTION: A pitch angle calculation section 22 of a pitch angle detection device 12 extracts a plurality of horizontal luminance groups being groups of luminance in a horizontal direction in reflection light Lr for each vertical direction, calculates a plurality of horizontal luminance mean values Lave being mean values of the luminance in individual ones of the plurality of horizontal luminance groups extracted and calculates an amount of change ΔAp of the a pitch angle Ap per unit time on the basis of a difference between horizontal luminance mean values Lave of previous and this time operation periods.;COPYRIGHT: (C)2015,JPO&INPIT
