摘　　要：空盒气压表是用于监测环境大气压力的仪表,其使用数据是通过校准或检定得到的。本文利用基于视频采集系统得出的数据详细地对其校准过程中可能引入的不确定度分量进行了分析和评定,得出扩展不确定度并与人工读取数据的结果加以比对,从不确定度方面论证视频数据采集的可行性。Aneroid Barometer is an instrument used to monitor ambient atmospheric pressure, and its service data is obtained through calibration or verification. In the paper, the uncertainty components that may be introduced in the calibration process are analyzed and evaluated in detail by using the data obtained based on the video capture system. The extended uncertainty is obtained and compared with the results of manual reading data, so as to demonstrate the feasibility of video data capture in terms of uncertainty.
