摘　　要：航天器人控交会对接过程中,空间光照环境极为复杂.摄像机作为最主要的相对测量敏感器,需要设计合理的调光算法以适应各种工况.详细分析了航天器的空间光照环境,针对人控交会对接的场景特点,对基于直方图的自动调光算法提出了改进措施,并提出了全面的地面验证测试方法,证明了改进后的直方图自动调光算法的合理性.During manual controlled rendezvous and docking of spacecraft, the space condition of illumination is very complex. As the most important relative measurement sensor, television camera needs to be designed with appropriate exposure algorithm so as to adapt every different condition. The space condition of illumination is analyzed in this paper. Aiming at the characteristic of manual controlled rendezvous and docking, the automatic exposure algorithm is improved based on luminance histogram, and the experimental verification approaches are proposed to prove its efficiency and availability.
