here, there is a lot of distance between two rows. and even between two plants there is significant distance where there is nothing to be sprayed. as the sprayer moves, the camera real—time detects where the spray should be applied, specifically on the plant. and it turns off the nozzles where there are no plans. and that saves over 50% of costs of chemicals. these have been deployed on 50 farms but are limited to just seven crops and that is because the machine needs volumes of data which are photos of the plants to learn from and build models for each crop. over the last five years we have captured about 8.2 million images across seven crops and not only that, the numbers is impressive, but also how varied the data is.
