摘　　要：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。Objective To offer a convenient and applied measure instrument for the study about visual performance and information processing of submariners in human-machine-environment system. Methods Instrument images in service using were collected with digital camera,processed with Photoshop image system and established to instrument image data-bank according to actual size. Furthermore, Delphi visualization software was used to develop advanced instruments and systemic operational software. The efficiency of submariner＇s visuognosis on instrument scales was measured by the window of man-maching dialogue. Results The tests were in two kinds of intensity luminous environments, respectively. When illumination of environment hoisted from 50 lx to 150 Ix, reaction time of testers to identify instrument was significant shorten （ P 〈 0.01 ）, at the same time,there were no obviously differences among testers to identify instrument（ P 〉 0.05 ）. Conclusions The system would be as a sensitive ,convenient and practical tool for the study of the efficiency of submariner＇s visuognosis on instrument scales to spread and use.
