吊车工人深度视觉阈值的测定

本研究对１０９名吊车工人进行了红橙黄绿蓝紫黑白等八种颜色的深度知觉阈限的测定．结果发现：在白色背景条件下，绿蓝两色为最佳深度色，最易辨别深度差异；黑紫红三色为二级深度色；橙黄两色为三级深度色；白色为四级深度色．易于深度辨别的颜色．，平均阈值小，分布较集中；不易深度辨别的颜色，平均阈值大，分布较分散．建议吊车设计部门，在吊钩臂部位的黄色背景上，涂上黑色条子．使吊车的吊钧本身具有颜色对比，少受作业环境的影响。

CRANE DRIVER'S DEPTH PERCEPTION THRESHOLDS

This research measures the depth perception thresholds of eight colors (red, orange, yellow, green, blue, purple,black and white)in 109 crane drivers. it is found that against a white background, green and blue are the best depth colors for distingulshing depth differences easily,black, purple and red are the grade-2 depth colors ,orange and yellow, grade-3 , white, grade-4. The colors easy of depth differentiation have low average-threshold-values and concentrated distributions, the colors less easy of depth differentiation have great average-threshold-values and dispensed distributions. We suggest that crane-design departments paint black stripes on the yellow background of the shank of the crane hook to add color contrast and lessen the affect of the working environment.
