Terrain relief shading enhancing system, device, and method

摘要

A system, device, and method for minimizing terrain content in an image are disclosed. The terrain content minimization system may include a source of navigation data, a source of first surface data, and an image generator (IG). The IG may be configured to acquire navigation data; acquire first surface data; identify first surface data as a function of an elevation range; generate first pixel data; generate second pixel; and employ at least one of the first pixel data and the second pixel data. Second surface data could be comprised of a first subset of the surface data, and the third surface data could be comprised of a second subset of the surface data not included in the second subset of the first surface data. In addition, the pixel data could be representative of an image of terrain of the surface data.

主权项

1. A system for enhancing relief shading of an image of terrain, comprising:
a presentation system comprised of at least one display unit configured to:
receive image data provided by
an image generator including at least one processor coupled to a non-transitory processor-readable medium storing processor-executable code for causing the at least one processor to:
acquire navigation data;acquire surface data based upon the navigation data and representative of a plurality of elevations defining at least one of a plurality of surfaces;determine whether at least one of the plurality of elevations falls within an elevation range;generate at least one of first pixel data and second pixel data in response to the determination, where the first pixel data is representative of at least one non-greyscale color generated by applying a coloring function to a first portion of the surface data representative of the at least one of the plurality of elevations falling within the elevation range, and the second pixel data is representative of at least one greyscale-only color generated by applying a shading function to a second portion of the surface data representative of the at least one of the plurality of elevations not falling within the elevation range; andemploy at least one of the first pixel data and the second pixel data as image data representative of an image of the at least one surface of a plurality of surfaces; andpresent the image represented in the image data on display unit other than a head-up display unit.
