Abstract

The invention belongs to the technical field of agriculture, in particular relating to a DSP (Digital Signal Processor)-based rice weed recognition system and method. The DSP-based rice weed recognition system consists of an image acquiring module, a rice weed recognition module and an image displaying module, wherein the image acquiring module and the image displaying module are connected with the rice weed recognition module respectively by virtue of an I2C (inter-integrated circuit) bus and a BNC (Bayonet Nut Connector) data bus; the image acquiring module consists of a CCD (charge-coupled device) camera supporting high-definition image and an SAA7115 decoding chip of Philips, the image displaying module consists of a Gadmei PL7006 liquid crystal television used for displaying a television signal, and the rice weed recognition module consists of a DM642DSP image processing chip, and expanding SDRAM (synchronous dynamic random access memory) and SAA7121 (system application architecture 7121) decoding chips. According to the invention, the real-time recognition of weeds in rice fields can be realized, and the system miniaturization and portability can lead the system to be capable of being flexibly arranged on rice planting field equipment, and improving the practical application range of the system.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to a DSP-based rice weed identification system and an identification method thereof. Background technique [0002] Weeds in crop fields bring great harm to crop growth. At present, the main methods of weeding in farmland are manual weeding, mechanical weeding, heat weeding, electrostatic weeding, chemical weeding, etc. Among them, chemical weeding is widely used because of its convenience. At present, the method of chemical weeding is an extensive spraying method, which not only causes a lot of waste of drugs, increases production costs, but also brings great harm to the ecological environment. With the introduction of precision agriculture, field miscellaneous Grass accurate recognition technology has become a research hotspot. [0003] Precise weeding is mainly for row crops (such as wheat, corn, soybean, rice, etc.). According to the spatial distribution characteristics, r...
