Abstract:
1. A vehicle surroundings monitoring device, comprising: a plurality of image capturing units installed in a vehicle to capture images of surroundings of the vehicle such that image capturing ranges, of adjacent image capturing units of the plurality of image capturing units, partially have an overlapping region; a virtual-screen setup unit configured to set up a virtual screen in the overlapping region of the image capturing ranges, the virtual screen extending in a direction from a near side to a far side of the vehicle and standing upright from a road surface in a vertical direction; a virtual-screen projection image generation unit configured to store a value corresponding to a gray value stored in each pixel of the image captured by each of the adjacent image capturing units of the plurality of image capturing units, at a position where a half line intersects the virtual screen, the half line extending from a position corresponding to a principle point of each of the plurality of image capturing units toward each pixel of the image captured by each of the plurality of image capturing units; a first viewpoint conversion unit configured to perform coordinate conversion in which an image generated by the virtual-screen projection image generation unit is converted to an image of observation from a predetermined viewpoint position in a predetermined sight-line direction and to output the converted image; and an image display unit configured to display the converted image outputted from the first viewpoint conversion unit wherein the virtual-screen setup unit sets a setup position of the virtual screen on a basis of a traveling direction of the vehicle.
