Abstract:
Present disclosure provides a travel assistance device which comprises: a road detection unit that obtains an infrared image in front of a vehicle from an infrared imaging unit that is mounted on the vehicle, and detects a road end line of a road on which the vehicle travels from the captured infrared image; a division line detection unit that obtains a visible image in a range corresponding to a range indicated by the infrared image from a visible imaging unit that is mounted on the vehicle, and detects a division line of the road from the captured visible image; an image generation unit that generates an integrated image indicating the road end line and the division line on the basis of the infrared image and the visible image registered with each other; and a division line estimation unit.

Claim (Index 3):
The travel assistance device according to  claim 1 ,\n wherein the image generation unit generates a first integrated image which is a two-dimensional image indicating the road end line and the division line as the integrated image on the basis of the infrared image and the visible image registered with each other, and the division line estimation unit performs a first estimation process of\n calculating an internal division ratio at which a reference point on one of two road end lines and a reference point on the other of the two road end lines are internally divided by a reference point on the division line on a line extending in a horizontal direction of the first integrated image in a state in which the first integrated image is arranged with a downward direction of the vehicle set as a downward direction of the image in a case where the two road end lines respectively indicating both ends of the road are detected, and \n calculating respective candidate points of the division lines according to a condition that a point on the one road end line, a point on the other road end line, and a point on the division line maintain the internal division ratio on a line extending in the horizontal direction passing through each point from each reference point to an intersection point of the two road end lines, and estimating the extended portion of the division line on the basis of the calculated candidate points of the division lines.
