ESTIMATION DEVICE AND ESTIMATION PROGRAM

摘要

An estimation device (10A) includes the following: an imaging unit (14) that images at least one of front and rear images of a vehicle (12); a movement amount calculation unit (24) that calculates a movement amount in a vertical direction of a prescribed region, on the basis of a position of the prescribed region within an image captured at a first time, and a position of a region corresponding to the prescribed region within the image captured from the same direction at a second time that is later than the first time; a movement amount integration unit (26) that calculates an integration value of the movement amount every time the movement amount is calculated; a correction unit (30) that corrects the integration value of the current point in time, on the basis of time series data of the integration values of the movement amounts over a prescribed period of time in the past; and an estimation unit (32) that estimates the pitch angle of the vehicle (12) on the basis of the corrected integration value.
