Image creation device and image creation method

Abstract

An embodiment of the present disclosure is an image creation device (20) which is mounted on a vehicle. The image creation device is provided with an image acquisition unit (S110) and a downward viewcreation unit (S120 to S160). The image acquisition unit acquires a taken image of a surrounding area of the vehicle. The downward view creation unit creates a downward view. The downward view creation unit is provided with an outline extraction unit (S120), an area determination unit (S120), a first creation unit (S270), a second creation unit (S130), and an image synthesis unit (S290). The outline extraction unit extracts an outline shape of an object in the taken image. The area determination unit determines whether an area of the outline shape is a three-dimensional object area or a road surface area. The first creation unit creates a three-dimensional view image, and the second creation unit creates a two-dimensional view image. The image synthesis unit synthesizes the three-dimensional view image and the two-dimensional view image.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This international application claims the priority of Japanese Patent Application No. 2018-38581 filed at the Japan Patent Office on March 5, 2018, and the entire content of Japanese Patent Application No. 2018-38581 is hereby cited. technical field [0003] The present disclosure relates to an image creation device and an image creation method for creating a bird's-eye view image from a captured image of a surrounding area of ​​a vehicle. Background technique [0004] There is known a system that converts an image of the surroundings of a vehicle captured by a plurality of on-vehicle cameras into a bird's-eye view image in which the surroundings of the vehicle are reflected from a virtual camera above the vehicle, and displays the images on a display provided in the vehicle. device to prompt the driver to assist safe driving. [0005] The conversion from the captured image to the bird's-eye view image, that is, the bi...

Problems solved by technology

[0008] However, as a result of detailed studies by the inventors, it has been found that in the method described in Patent Document 1, there is a possibility that the shape and color of the three-dimensional object displayed on the composite image may not match the actual three-dimensional object.

A problem has been found that if such a composite image is displayed, the driver may feel a sense of incongruity due to the inconsistency of the shape, color, etc.
