瞳孔能自动调节进入眼球的光通量、使视网膜感光适度,但调节速度比较慢。一般从亮到暗的适应时间为30秒;从暗到亮的适应时间为20秒左右。如果亮度突然急速变化,不但会使人感到耀眼炫目或漆黑一片,而且有害眼睛健康。所以一些较考究的电... 瞳孔能自动调节进入眼球的光通量、使视网膜感光适度,但调节速度比较慢。一般从亮到暗的适应时间为30秒;从暗到亮的适应时间为20秒左右。如果亮度突然急速变化,不但会使人感到耀眼炫目或漆黑一片,而且有害眼睛健康。所以一些较考究的电影院、录像厅等,在映出前后主场灯的开与关,都很注意使其亮度逐渐变化。本文所述装置电路简单(见附图),价位低廉,制作容易。本装置也可用于家庭照明灯光的控制。原理简述如下: 展开更多

This paper presents some human-inspired strategies for lighting control in a robot system for best scene interpretation,where the main intention is to avoid possible glares or highlights occurring in images. It firstly compares the characteristics of human eyes and robot eyes. Then some evaluation criteria are addressed to assess the lighting conditions. A bio-inspired method is adopted to avoid the visual glare which is caused by either direct illumination from large light sources or indirect illumination reflected by smooth surfaces. Appropriate methods are proposed to optimize the pose and optical parameters of the light source and the vision camera. 展开更多
