METHOD FOR VISUALIZATION OF POINT CLOUD DATA
First Claim
1. A method for providing a color representation of three-dimensional range data for improved visualization and interpretation, comprising:
- displaying a plurality of data points comprising said three-dimensional range data using a color space defined by hue, saturation, and intensity;
selectively determining respective values of said hue, saturation, and intensity in accordance with a color map for mapping said hue, saturation, and intensity to an altitude coordinate of said three-dimensional range data;
selecting said color map so that values defined for said saturation and said intensity have a first peak value at a first predetermined altitude approximately corresponding to an upper height limit of a predetermined target height range.

Abstract
Method for providing a color representation of three-dimensional range data (200) for improved visualization and interpretation. The method also includes selectively determining respective values of the hue (402), saturation (404), and intensity (406) in accordance with a color map (FIG. 5, 6) for mapping the hue, saturation, and intensity to an altitude coordinate of the three-dimensional range data. The color map is defined so that values for the saturation and the intensity have a first peak value at a first predetermined altitude approximately corresponding to an upper height limit (308) of a predetermined target height range (306). Values defined for the saturation and the intensity have a second peak at a second predetermined altitude (310) corresponding to an approximate anticipated height of tree tops within a natural scene.
