1. A peripheral image generation device for a vehicle, comprising:
an image acquisition unit configured to acquire a plurality of camera images obtained from a plurality of cameras each of which captures a periphery of the vehicle;
an image storage unit configured to store a traveling direction camera image that is a part or all of images included in the plurality of camera images and captured at least in a traveling direction of the vehicle; and
a composite image generation unit configured to generate an underfloor transparent image that is a composite image transmitting a bottom of the vehicle based on the plurality of camera images and the traveling direction camera image, wherein
the composite image generation unit generates, as the underfloor transparent image, an image in which (i) a vehicle boundary line indicating a boundary of a range of a vehicle body and a tire boundary line indicating a boundary of a range of a tire are superimposed on an image showing a part or all of ground located under the vehicle, wherein the vehicle boundary line is a line showing a boundary of a region formed by projecting the vehicle body perpendicularly to a road surface, and the tire boundary line is a line showing a boundary of a region formed by projecting the tire perpendicularly to a road surface, and (ii) a decoration having a predetermined pattern is added to at least the vehicle boundary line, wherein the decoration is placed outside the vehicle boundary line.
