The modular construction, used in the software of the system, consists of image input, output, processing, editing and analysing units as well as image database and graphics processing device.
According to the modular idea, the whole hardware system is divided into two pieces of hardware, which is the core processing module and data collecting modules.
系统硬件设计方面，根据模块化的设计思路，将整个硬件系统分为两块，分别是核心处理模块和数据采集模块。
