英文摘要：

In order to achieve short - range wireless image transmission and processing as well as pro-vide an initial prototype for intelligent machine vision, a system scheme of short - range wireless imagetransmission and processing based on solar power is put forward. For driving the Buck charging cir-cuit, a high - efficiency MPPT charging algorithm is used to implement solar power supply. The hard-ware structure of CPLD ＋ ARM ＋ SRAM is adopted to realize image acquisition, and the design of pow-er amplifier circuit and low -noise amplifier circuit is utilized to achieve the wireless image transmis-sion. Besides, a novel local iterative Otsu image threshold processing algorithm is developed on PCclient. A good effect has been achieved by joint debugging of systematic software and hardware. Fur-thermore, the system can meet the demand in the field of computer vision.
