A method for detecting residue bunches within a field, the method including receiving, with a computing system, one or more images depicting an imaged portion of an agricultural field, the imaged portion of the field being at least partially represented by a plurality of pixels within the one or more images, the one or more images comprise a depth image of the imaged portion of the agricultural field, each of the plurality of pixels within the depth image being associated with a respective pixel height, the pixel height corresponding to a relative height of residue within the field obtained from the depth image, the method being characterized by classifying, with the computing system, a portion of the plurality of pixels that are associated with crop residue within the imaged portion of the field as residue pixels, each residue pixel being associated with a respective pixel height; determining, with the computing system, a reference height based on at least a portion of the respective pixel heights of the plurality of pixels within the depth image; defining, with the computing system, a pixel height threshold based at least in part on the reference height; classifying, with the computing system, another portion of the plurality of pixels that are associated with soil within the imaged portion of the field as soil pixels, each soil pixel being associated with a respective pixel height; wherein determining the reference height comprises: calculating an average height of the soil based at least in part on the pixel heights of the soil pixels; and calculating the reference height based at least in part on the average height of the soil; the method further comprising identifying, with the computing system, each residue pixel having a pixel height that exceeds a pixel height threshold as a candidate residue bunch pixel; and determining, with the computing system, whether a residue bunch is present within the imaged portion of the field based at least in part on the candidate residue bunch pixels, wherein determining whether a residue bunch is present within the imaged portion of the field comprises determining an area associated with the candidate residue bunch pixels; comparing the area to a predetermined area threshold; and determining that a residue bunch is present within the imaged portion of the field when the area associated with the candidate residue bunch pixels exceeds the predetermined area threshold. classifying, with the computing system, a portion of the plurality of pixels that are associated with crop residue within the imaged portion of the field as residue pixels, each residue pixel being associated with a respective pixel height;
