Systems and methods for displaying images with multi-resolution integration

摘要

A display system is provided for a vehicle. The system includes a first data source configured to provide low resolution terrain data; a second data source configured to provide high resolution terrain data; a processing unit coupled to the first data source and the second data source, the processing unit configured to receive the low resolution terrain data and high resolution terrain data, to integrate the low resolution terrain data and the high resolution terrain data into a common three-dimensional view that includes graphical elements representing both the low and the high resolution terrain data, and to supply display commands associated with the low and the high resolution terrain data; and a display device coupled to the processing unit and configured to receive the display commands and operable to render the common three-dimensional view to thereby allow simultaneous viewing of the low and the high resolution terrain data.

1. A display system for a vehicle, comprising:
a first data source configured to provide low resolution terrain 3D geometry data; a second data source configured to provide high resolution terrain 3D geometry data; a processing unit coupled to the first data source and the second data source, the processing unit configured to receive the low resolution terrain 3D geometry data and high resolution terrain 3D geometry data, to integrate the low resolution terrain 3D geometry data and the high resolution terrain 3D geometry data into a common three-dimensional view that comprises graphical elements representing both the low resolution terrain 3D geometry data and the high resolution terrain 3D geometry data by forming at least one low resolution mesh strip of the low resolution terrain 3D geometry data corresponding to a FOV, identifying any intersections of a high resolution patch of the high resolution terrain 3D geometry data within the FOV and the at least one low resolution mesh strip, removing a portion of the at least one low resolution mesh strip intersected by the high resolution patch, patching the high resolution patch into the removed portion of the at least one low resolution mesh strip, and blending a boundary between the low resolution terrain 3D geometry data and the high resolution terrain 3D geometry data, and to supply display commands associated with the low resolution terrain 3D geometry data and the high resolution terrain data; and a display device coupled to the processing unit and configured to receive the display commands and operable to render the common three-dimensional view to thereby allow simultaneous viewing of the low resolution terrain 3D geometry data and the high resolution terrain 3D geometry data.
