SDOP is the solution for identifying rodents and harmful lepidoptera in fields at the optimal moment, before their overproduction. It enables fast and affordable remote detection of pests on large agricultural fields using combination of optical and acoustic detectors. By deploying acoustic detectors in the soil and above the ground and combining the measured values with the visible and infrared video feeds from drones, the decision if the area is affected with pests is made. Different levels of services will be provided to the user such as: Remote visual inspection Combination of visual and acoustic data inspection Automatic detection and notification The detection methods can be adopted to other types of pests depending on the geographical regions, type of crops or other parameters.
