  • Publication number: 20240331241
    Abstract: Where a first bird's-eye-view image is generated by merging images obtained from multiple image capturing devices in a moving body together and an overlapping image is generated from accumulated images and overlaps the moving body, a second bird's-eye-view is generated by merging the first bird's-eye-view image and the overlapping image together. In the boundary portion formed between the first bird's-eye-view image and the overlapping image, a coefficient calculation part calculates adjustment coefficients for adjusting the property of the overlapping image based on property information of the first bird's-eye-view image and the accumulated images. An adjustment part adjusts the property of the overlapping image to be merged by the merging part based on the adjustment coefficients. By this means, it is possible to reduce the possibility that, when the first bird's-eye-view image and the overlapping image not included in the first bird's-eye-view image are merged together, the resulting image looks unnatural.
