A method for calibrating crop residue data for a field acquired using a vision-based system may include receiving image data associated with an imaged portion of the field, analyzing the image data using a first residue-estimating technique to determine a first estimated value of a crop residue parameter for the imaged portion of the field, and analyzing the image data using a second residue-estimating technique to determine a second estimated value of the crop residue parameter for the imaged portion of the field. In addition, when a differential exists between the first and second estimated values, the method may also include adjusting at least one of the first estimated value or one or more additional estimated values of the crop residue parameter determined using the first residue-estimating technique based on at least one of the second estimated value or the differential between first and second estimated values.
