A low-cost agricultural field video/image fast acquisition system

Agricultural field image information acquisition is an important way of crop growth and pest analysis. In this paper, a lowcost agricultural field camera video/image acquisition system was designed with high-resolution image sensor Logitech Pro9000 based on embedded technology and B/S architecture. The system architecture, communication sub-system, acquisition sub-system, data compression and transmission sub-system was designed in detail in this paper. The system embedded a high-power WiFi, fast ARM platform S3C6410 processor, V4L2 technology acquisition image and the JPEG image data compression technology to guarantee the ratio of video transmission. Experimental results showed that the system could reach more than 92% of the successful image transmission velocity for the transmission of a 640*480 image to a remote server within the distance of 300 m, and the transmission velocity achieved 20 frames per second within a distance of 50 m or more. It also could achieve more than 6 frames per second in the distance of 300 m. Since the program was based on the ARM platform, it was low cost. This scheme was very suitable for a wide range of agricultural application.
