摘要： An image generation device generates an output image based on input images captured by three cameras. An input image portion corresponding to an overlap region of imaging ranges of the cameras forms a lattice pattern in the output image. The lattice pattern uses, as a unit pattern, lattice points divided by circles drawn by waves around two cameras. Pixel values of the unit pattern are obtained by weight-averaging pixel values of first and second input images. A weighted average value of pixel values of the first input image is equal to or larger than a weighted average value of pixel values of the second input image in one of two unit patterns through which an abdominal line and a nodal line pass, and is equal to or smaller than the weighted average value of the pixel values of the second input image in the other one thereof.

摘要： An image generating apparatus for a paving machine, which generates an output image based on input images captured by multiple image capturing parts attached to the paving machine, includes a coordinates correlating part that correlates coordinates in a space model disposed around the paving machine with coordinates in input image planes in which the input images are positioned and an output image generating part that generates the output image by correlating the values of the coordinates in the input image planes with the values of coordinates in an output image plane in which the output image is positioned, via the coordinates in the space model. The space model includes a first plane area parallel to a road surface and a second plane area that intersects the road surface. The second plane area is set at the front end of the paving machine in a traveling direction of the paving machine.

摘要： An image generation apparatus includes a processor that generates an output image based on input images captured by multiple imaging units mounted on a paver including a hopper, a tractor, and a screed. The output image includes a hopper image representing a downward view of the hopper, a left-side surrounding image representing a downward view of a surrounding area on the left side in a movement direction of the paver, a right-side surrounding image representing a downward view of a surrounding area on the right side in the moving direction of the paver, and an illustration image of the tractor. The processor arranges the hopper image, the left-side surrounding image, the right-side surrounding image, and the illustration image such that the output image represents a downward view of the paver.

摘要： An image generation device generates an output image based on an input image captured by a camera attached to a shovel. Further, the image generation device includes an output image generation unit that associates a value of an input pixel in the input image with a value of an output pixel in the output image to generate the output image. A value of an output pixel specified by an integer coordinate point on an output image plane is determined based on values of two input pixels specified by two integer coordinate points selected from four integer coordinate points in the vicinity of a real number coordinate point on an input image plane corresponding to the integer coordinate point on the output image plane.
