Method and apparatus for automated plant necrosis

摘要

A method of distinguishing individual plants within a row of plants, including directing radiation at the row of plants at an angle selected to illuminate a portion of the plant and cast a shadow at the plant center, collecting an image from the radiation reflected off of two or more contiguous plants with a detector, identifying a continuous foreground region indicative of a plant within the image, identifying points of interest within the region, classifying the points of interest as plant centers and non-plant centers, and segmenting the region into sub-regions, each sub-region encompassing a single point of interest classified as a plant center.

主权项

1. A method of distinguishing individual plants within a row of plants extending from a ground, comprising:
illuminating two contiguous plants within the row at an angle between the ground and a normal vector to the ground with a light; collecting an image of the two plants with a camera oriented with a view plane substantially parallel to the ground; identifying a continuous region indicative of a plant; identifying points of interest within the region based on gradients identified within the region, wherein points of interest comprise portions of the region having gradients greater than a gradient threshold; selecting a first and a second point of interest; and segmenting the region into a first and a second sub-region encompassing the first and the second selected points of interest, respectively.
