摘　　要：在非扫描激光三维成像系统中,各分系统(部件)接口众多、关系复杂。各单元需要在适当的时序控制下实时完成各自的功能,主控电路在系统中负责时序控制、数据采集、处理运算、接口通讯等功能,是系统的核心部件之一。本文采用DSP和FPGA相结合的方式,充分利用它们各自的控制灵活、实时运算的特点,完成了主控电路的上述功能,实现了成像过程全自动、帧频达到25Hz的要求,为实现原理样机转化为工程样机打下了技术基础。In non-scanning laser 3D imaging system,there are many sub-systems（ components） which need to run real-time according to a proper sequence. The main control part has the functions of sequence controlling,data collecting,result computing,communicating and interface controlling,and it is one of the core parts. According to the characteristics of DSP and FPGA,the combined structure of DSP and FPGA is adopted to implement the main control part. Automatic imaging is achieved and the frame rate reaches 25 Hz. This contributes to the engineerization of the prototype.
