摘要

针对动量球转子全姿态空间测量的应用需求，该文对转子按照经纬度渐变的颜色编码方案进行了改进，分析了编码纬度范围与传感器分布之间的关系，提出一种按照三正交轴渐变的颜色编码方案，该编码方案具有颜色分布均匀，颜色矢量与坐标值之间的映射关系更为直接等特点。仿真实验验证了2种渐变色编码测量方案在全姿态空间范围内快速方位测量的可行性，比较了2种方法的测量误差，结果表明：按照三轴渐变色的编码方式具有更好的测量精度。

Abstract

Orientation sensing of the full-attitude of a reaction sphere recognized accurate sensing of the color changes with latitude and longitude. This study analyzed the relation between the latitude range and the sensor distribution. A gradient color coding strategy was developed with the RGB colors changing along 3 orthogonal axes. This coding method provides a uniform color distribution and direct correspondence between the color and the coordinates. Simulations show the feasibility of using two gradient color codes for fast orientation sensing at full-attitude with smaller errors than with second coding.
