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.

Description

technical field [0001] The present invention relates to the field of visualization of point cloud data, and more particularly relates to the visualization of point cloud data based on scene content. Background technique [0002] Three-dimensional (3D) type sensing systems are commonly used to generate 3D images of locations for use in various applications. For example, such 3D images are used to create secure training or planning environments for military operations or civilian activities, for generating topological maps, or for surveillance of locations. Such sensing systems typically work by capturing location-related elevation data. One example of a 3D-type sensing system is a light detection and ranging (LIDAR) system. LIDAR-type 3D sensing systems produce data by recording multiple distanced echoes from a single laser pulse to produce frames (also sometimes referred to as image frames). Thus, each image frame of LIDAR data will contain a collection of three-dimension...
