摘要(Abstract)：

在现实场景中开展仿真假体视觉下寻路任务研究。受试者佩戴头戴式显示器,由显示器上方的摄像装置获取外界图像,并通过数据传输线连接电脑对实时场景图像进行像素化处理。实验采用标准轮滑桩摆设实验通路,要求受试者佩戴头戴式显示器在预先摆设通路中寻路和判别方向,并对寻路时间、寻路碰撞次数等进行分析研究。结果表明:分辨率为64×64时寻路时间最短;分辨率由32×32增加至48×48,寻路时间减少40%,碰撞次数减少43%;分辨率由48×48增至64×64,寻路时间减少22%,碰撞次数减少31%。随着实验分辨率提升,寻路时间和碰撞次数明显减少。受试者性别和实验时间(白天/晚上)无显著性差异,女性受试者在白天实验效果较好。该研究可为人工视觉假体系统的设计和开发提供前期的理论储备。

关键词(KeyWords)： 寻路任务;视觉假体;像素化处理;分辨率;寻路时间;碰撞次数
