Method for visualization of point cloud data based on scene content
First Claim
1. A method for improving visualization and interpretation of spatial data of a location, comprising:
- selecting a first scene tag from a plurality of scene tags for a first portion of a radiometric image data of said location;
selecting a first portion of said spatial data, said spatial data comprising a plurality of three-dimensional (3D) data points associated with said first portion of said radiometric image data;
selecting a first color space function for said first portion of said spatial data from a plurality of color space functions, said selecting based on said first scene tag, and each of said plurality of color space functions defining hue, saturation, and intensity (HSI) values as a function of an altitude coordinate of said plurality of 3D data points; and
displaying said first portion of said spatial data using said HSI values selected from said first color space function using said plurality of 3D data points associated with said first portion of said spatial data,wherein said plurality of scene tags are associated with a plurality of classifications, and wherein each of said plurality of color space functions represents a different pre-defined variation in said HSI values associated one of said plurality of classifications.

Abstract
Systems and methods for associating color with spatial data are provided. In the system and method, a scene tag is selected for a portion 804 of a radiometric image data (800) of a location and a portion of the spatial data (200) associated with the first portion of the radiometric image data is selected. Based on the scene tag, a color space function (500, 600) for the portion of the spatial data is selected, where the color space function defines hue, saturation, and intensity (HSI) values as a function of an altitude coordinate of the spatial data. The portion of the spatial data is displayed using the HSI values selected from the color space function based on the portion of the spatial data. In the system and method, scene tags are each associated different classifications, where each color space function represents a different pre-defined variation in the HSI values for an associated classification.
