Abstract
A method for determining residue length within a field includes receiving, with a computing system, a captured image depicting an imaged portion of the field from one or more imaging devices. Furthermore, the method includes determining, with the computing system, an image gradient orientation at each of a plurality of pixels within the captured image. Additionally, the method includes identifying, with the computing system, a residue piece present within the image portion of the field based at least in part on the determined image gradient orientations. Moreover, the method includes determining, with the computing system, a length of the identified residue piece.
Claims18
A method for determining residue length within a field, the method comprising:
- receiving, with a computing system, a captured image depicting an imaged portion of the field from one or more imaging devices;
- determining, with the computing system, an image gradient orientation at each of a plurality of pixels within the captured image;
- identifying, with the computing system, a residue piece present within the image portion of the field based at least in part on the determined image gradient orientations, wherein identifying the residue piece comprises:
- generating, with the computing system, a composite image depicting the image gradient orientation at which a maximum local density of the image gradient orientations occurs for the plurality of pixels;
- and
- generating, with the computing system, a plurality of binary images based on the composite image, each binary image corresponding to one of a plurality of predetermined image gradient orientations such that each binary image depicts one or more pixels of the plurality of pixels at which the maximum local density of the image gradient orientations occurs at the corresponding predetermined image gradient orientation;
- and
- determining, with the computing system, a length of the identified residue piece.
A system for determining residue length within a field, the system comprising:
- an imaging device configured to capture images of a field;
- and
- a computing system communicatively coupled to the imaging device, the computing system including a processor and associated memory, the memory storing instructions that, when implemented by the processor, configure the computing system to:
- receive a captured image depicting an imaged portion of the field from one or more imaging devices;
- determine an image gradient orientation at each of a plurality of pixels within the captured image;
- identify a residue piece present within the image portion of the field at least in part based on the determined image gradient orientations, wherein, when identifying the residue piece, the computing system is configured to:
- generate a composite image depicting the image gradient orientation at which a maximum local density of the image gradient orientations occurs for the plurality of pixels;
- and
- generate a plurality of binary images based on the composite image, each binary image corresponding to one of a plurality of predetermined image gradient orientations such that each binary image depicts one or more pixels of the plurality of pixels at which the maximum local density of the image gradient orientations occurs at the corresponding predetermined image gradient orientation;
- and
- determine a length of the identified residue piece.
