Abstract
A method of taking an aerial survey maps boundaries of a first image and a second image from a first plane to a second plane to determine boundaries of an output image in the second plane. For a plurality of pixels in the output image, the method determines a corresponding pixel of either the first image or second image in the first plane.
Claims15
A computer-implemented method of generating a mosaic digital image from a plurality of pixilated images, the method comprising:
- defining an output image having a resolution and comprising a plurality of output image portions, each output image portion comprising at least one output pixel;
- receiving a plurality of input images, each input image of the plurality of input images being of a corresponding ground area of an astronomical body and comprising a plurality of input pixel values;
- mathematically dividing the ground area of the astronomical body, based on the resolution of the output image, to define a plurality of ground area portions;
- using ray-tracing mathematics to map each ground area portion of the plurality of ground area portions to a corresponding output image portion of the plurality of output image portions;
- and
- assigning values to the at least one output pixel of the output image, based on the mapping of the plurality of ground area portions to the plurality of output image portions and the input pixel values in the plurality of input images.
A system for generating a mosaic digital image from a plurality of pixilated images, the system comprising:
- a computer processor programmed to:
- define an output image having a resolution and comprising a plurality of output image portions, each output image portion comprising at least one output pixel;
- receive a plurality of input images, each input image of the plurality of input images being of a corresponding ground area of an astronomical body and comprising a plurality of input pixel values;
- mathematically divide the ground area of the astronomical body, based on the resolution of the output image, to define a plurality of ground area portions;
- use ray-tracing mathematics to map each ground area portion of the plurality of ground area portions to a corresponding output image portion of the plurality of output image portions;
- and
- assign values to the at least one output pixel of the output image, based on the mapping of the plurality of ground area portions to the plurality of output image portions and the input pixel values in the plurality of input images.
A computer program product for generating a mosaic digital image from a plurality of pixilated images, the computer program product comprising a tangible, non-transitory computer-readable medium having computer readable program code stored thereon, the computer readable program code configured to cause a processor to:
- define an output image having a resolution and comprising a plurality of output image portions, each output image portion comprising at least one output pixel;
- receive a plurality of input images, each input image of the plurality of input images being of a corresponding ground area of an astronomical body and comprising a plurality of input pixel values;
- mathematically divide the ground area of the astronomical body, based on the resolution of the output image, to define a plurality of ground area portions;
- use ray-tracing mathematics to map each ground area portion of the plurality of ground area portions to a corresponding output image portion of the plurality of output image portions;
- and
- assign values to the at least one output pixel of the output image, based on the mapping of the plurality of ground area portions to the plurality of output image portions and the input pixel values in the plurality of input images.
