目的为开展“人-机-环境”系统中艇员视觉工效、信息处理的研究提供方便、实用的检测手段。方法用数码相机采集艇上实际应用的仪表图像,运用Photoshop图像处理系统,依据仪表的实际尺寸建立图像资料库,利用Delphi可视化软件开发工具,编制系统的操作软件,利用人机对话窗口对被试者进行辨认仪表刻度效率的测定。结果在2种不同强度的照明环境中进行测试。当环境照度由75 lx升高到150 lx时,被试者辨认仪表刻度的反应时间明显缩短(P<0.01);辨认仪表刻度的正确率差异无统计学意义(P>0.05)。结论该系统对艇员仪表刻度视觉辨认效率的测量敏感、方便、实用,适于普及和应用。
Aim To provide a convenient and practical test tool for the research of crew ’s ergonomics and information processing in the “man - machine - environment” system. Methods A digital camera was used to collect the instrumentation images of ships. The Photoshop image processing system was used to build an image database according to the actual size of the instrument. Delphi visualization software development tools were used to compile the operating software of the system. To determine the instrument calibration efficiency. The results were tested in two different intensity lighting environments. When the ambient illuminance increased from 75 lx to 150 lx, the response time of the subjects to identify the instrument scale was significantly shortened (P <0.01). There was no significant difference in the accuracy of the instrument scale identification (P> 0.05). Conclusion The system is sensitive, convenient, practical and suitable for the popularization and application of the measuring efficiency of the crew meter scale.
