Özet

While pesticide use is very important for weed control in agriculture, it is critical due to environmental contamination. In this study, a novel camera-integrated spraying needle nozzle design for targeted micro-dose spraying in precision weed control was developed in order to avoid excessive pesticide use. The micro-dose spraying system consisted of a camera, two pan-tilt units with servomotors assembled together to provide a 360-degree spraying capability for artificial weed samples, and spraying equipment. All the system automation and image processing processes were evaluated and controlled using LabVIEW software. The shooting capability and spraying performance of the novel camera-integrated spraying needle nozzle were tested and evaluated under laboratory conditions using artificial weed samples placed on a conveyor belt. The greenness method was used to detect the artificial weed targets on the conveyor belt. After image capturing, the coordinates of all artificial weeds in the field of view were calculated, and micro-dose spraying was then carried out for each artificial weed sample one by one until all the samples were sprayed. Positional error tests were carried out to assess the targeting performance of the spraying system. Deposition experiments were also carried out using filter papers to evaluate the spraying efficiency of the micro-dose spraying system under 200 kPa spraying pressure. A conveyor belt was set up for carrying the filter papers. The positional error test results showed that the weeding mean positional errors were 7.72 mm, 22.40 mm and 23.34 mm for the centre, left and right sides of the conveyor belt, respectively. The deposition concentration results showed that, while the mean deposition was 1.923 ng ml(-1) for the centre, the mean depositions were 1.567 ng ml(-1) and 1.494 ng ml(-1) for left and right sides, respectively. Higher spraying efficiency was determined in the centre compared to the left and right sides according to the amount of deposition results. The novel micro-dose spraying system has been experimentally tested and found to be very efficient.
