TLDR
In this article, a device for displaying a bird's eye view image around vehicle that enables a driver to recognize a solid obstacle near a joint, in a relatively simple manner and without imposing a processing load.Abstract:
PROBLEM TO BE SOLVED: To provide a device for displaying a bird's eye view image around vehicle that enables a driver to recognize a solid obstacle near a joint, in a relatively simple manner and without imposing a processing load. SOLUTION: The device for displaying bird's eye view image around vehicle includes a plurality of on-vehicle cameras for taking images of the vehicle's perimeter; an image conversion processing means including lens distortion correction processing, visual point conversion processing, display region cutting-out processing, and a synthesizing means for connecting and composing the cut out display region to create a bird's eye view image around vehicle which are applied to images photographed by the cameras; and a display means for presenting the driver and vehicle occupants with the bird's eye view image. The image conversion processing means, further, includes a reference height change means for sequentially creating the bird's eye view images, with respect to a second to (n +1)th reference heights (n is an integer of 1 or larger) which are progressively higher than a road surface level, in addition to the road surface level (first reference height), and set a first to (n+1)th bird's eye view images.

Method and device for detecting material object
TL;DR: In this article, the object regions occupied by the objects having heights and existing outside the referential plane are extracted from differences among the projected images, and then a plurality of virtual planes are set parallel to the original object regions on the upper and lower sides of the object region by a space scanning method processing device.
