Design On Intelligent Weeding System Based On Android

In agricultural greenhouses,the weeds will compete with the crops for the resources,so weeding is one of the necessary tasks in the agricultural production process.To save labor and reduce the use of herbicides,and agricultural users can remotely weed anytime and anywhere.In summary,this paper designs an intelligent weeding system based on Android.Intelligent weeding hardware system collects crop images through the image acquisition module,the control module uses the method of extracting location features to recognize the captured images,after the preprocessing such as graying,histogram equalization,filtering,denoising,and canny edge extraction,then use threshold segmentation and filtering crop lines to get the coordinates of weeds.Sending this coordinate to android client via 3G module,and next the android client sends a remote instruction to the weeding execution module through the operation interface,the weeding execution module generates the PWM signal according to the received instruction,in this way,the steering gear is moved so that the robotic arm completes the weeding action.Android client uses eclipse as development application,data interaction uses JSON data conversion format.Through this application,users can view the identification of weeds in real time,send instructions to control robotic arm weeding automatically.And on the Android client interface,you can control the movement of the robotic arm by dragging the slider,so that agricultural users can remotely weed the plant anytime and anywhere.
