Description Not Available
A microcontroller based manually operated three row roller contact type herbicide applicator was
designed and developed for control of the weed population in field crops. A control system was developed
to apply the quantity of the herbicide based on quantified weed information. The unit consists of a camera
for capturing the images of weeds, MATLAB software for image acquisition and processing in a laptop,
a serial port communication for communicating between laptop and controller, a microcontroller for controlling
the application of herbicide through a relay, and a dc solenoid valve for variable rate application
of herbicide on the applicating roller. The captured image was analyzed by the image processing toolbox
in the MATLAB software, to extract weed information in the image, which is then transferred to a microcontroller
using serial port interface. The microcontroller activates the solenoid valve using a relay
according to algorithm for decision of the herbicide amount. Field test results of the machine indicate
an average of 50% saving in the amount of herbicide, with weeding efficiency of 90%.
