process for recognition of a leaf edge, process for objective treatment of plants with a leaf treatment agent and use of an event-based image sensor for recognition of a leaf edge

摘要

the invention relates to a process (10) for recognizing a leaf edge with the following steps: - detection (110) of events in an image of a plant-covered soil at a speed of displacement in relation to the soil, being that a ground resolution of the image is between 0.5 and 1 mm per pixel; being that, before a first pixel of the image, a bandpass filter of a first frequency band is arranged and, before a second pixel of the image, a bandpass filter of a second frequency band is arranged; and - determining (120) that a leaf edge was recognized, if the first pixel at a first moment t1 detected at least one event of a first polarity and the second pixel at a time t2 detected at least one event of a second polarity , where the first and second polarities are opposite, and that the first at least one event of the first polarity of the first pixel and the at least one event of a second polarity of the second pixel correspond to the same location on the plant-covered soil, or whether the detected events were acknowledged or only on the first or second pixel. the invention also relates to the use of an event-based image sensor for recognizing a leaf edge, a computer program, a storage medium and an electronic control device.
