A vehicle surroundings monitoring device wherein, the vehicle surroundings monitoring device comprises: a plurality of image capturing units (22, 24, 26, 28) installed in a vehicle to capture images of surroundings of the vehicle such that adjacent ones of image capturing ranges of the image capturing units (22, 24, 26, 28) partially have an overlapping region (E1, E2, E3, E4); a virtual-screen setup unit configured to set up a planar virtual screen (200,210,220,230) in the overlapping region (E1, E2, E3, E4) of the image capturing ranges, the planar virtual screen (200,210,220,230) 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 of pixels of the image captured by each of adjacent ones of the image capturing units (22, 24, 26, 28), the value being stored at a position where each half line intersects the planar virtual screen (200, 210, 220, 230), and each of the half lines extending from a position corresponding to a starting point (P, Q) of the each image capturing unit (22, 24, 26, 28) toward the each pixel of the image captured by the each image capturing unit (22, 24, 26, 28); 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 image outputted from the first viewpoint conversion unit. a plurality of image capturing units (22, 24, 26, 28) installed in a vehicle to capture images of surroundings of the vehicle such that adjacent ones of image capturing ranges of the image capturing units (22, 24, 26, 28) partially have an overlapping region (E1, E2, E3, E4); a virtual-screen setup unit configured to set up a planar virtual screen (200,210,220,230) in the overlapping region (E1, E2, E3, E4) of the image capturing ranges, the planar virtual screen (200,210,220,230) 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 of pixels of the image captured by each of adjacent ones of the image capturing units (22, 24, 26, 28), the value being stored at a position where each half line intersects the planar virtual screen (200, 210, 220, 230), and each of the half lines extending from a position corresponding to a starting point (P, Q) of the each image capturing unit (22, 24, 26, 28) toward the each pixel of the image captured by the each image capturing unit (22, 24, 26, 28); 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 image outputted from the first viewpoint conversion unit.
