本文建立了一个以TP801单板机为核心的照相机综合参数检测系统,可检测曝光值偏差⊿EV、曝光时间T和光圈数F等参数。与传统的单项参数检测仪相比,该系统具有一机多用,结构简单,成本低廉,不需定期定标;误差小等优点。可供照相机生产厂和商检部门使用。 In this paper, a TP801 single-board camera as the core of a comprehensive parameter detection system can detect the exposure value deviation ⊿ EV, exposure time T and aperture F and other parameters. Compared with the traditional single parameter detector, the system has the advantages of a multi-purpose machine, simple structure, low cost, no need of regular calibration and small error. For the camera manufacturer and the use of commodity inspection departments.
