Performance Requirements
Mandatory | M.P. 1 - The system will gather relevant data from soybean plants at least 50 cm tall The data gathered should be useful in terms of resolution, overlap, and coverage Minimum Object Distance: 200mm from minimum object distance Pixel Density: > 1mm/px at far distance Vertical Overlap: > 10% Vertical Coverage: > 50cm M.P. 2 - The system will gather data for at least 30 min per charge Battery Life: > 30 min M.P. 3 - The system will localize itself with respect to the seeming lines with an error of at most 5 cm Error: < 5cm M.P. 4 - The system will estimate the number of pods with an error rate of at most 10% Error Rate: < 10% per meter (with respect to images, not ground truth) |
Desirable | D.P. 1 - The system will navigate by itself along a plot at a speed of at least 0.25m/s for at least 2m Frame Rate: > 10 fps Horizontal Overlap: > 80% Vehicle Speed: > 0.25m/s D.P. 2 -The system will estimate the dimensions of the pods with an error rate of at most 20% per grain Error: < 20% per grain (e.g. for 3 grains, < 3mm in diameter and < 1cm in length) D.P. 3 - The system will estimate the number of pods per grain with an error rate of at most 1/2 grain per pod Error: < 1/2 grain per pod |
Non Functional Requirements
Mandatory | M.N. 1 - The system will be transportable with a pick-up truck or trailer Volume: < 1.5mx1.5mx1.5m Loading into Truck: Lift or Ramp M.N. 2 - The system will be maneuvered by at most two operators Free Movement in the Field: Yes Mobility: <= 2 persons Operations: 1 person M.N. 3 - The system will fit in soybean plots Row Spacing: = 52cm Plant Height: <= 1.2m Plant Spread: <= 20cm M.N. 4 - The system will work in a level field in daylight Considerations: Lighting, Vibrations, Dirt |
Desirable | D.N. 1 - The system will follow the guidelines of the MRSD program Budget: < $5,000 Timeline: FVE (December 1st) and SVE (May 1st) D.N. 2 - The system will enable future development for the sponsor Considerations: Communication and Documentation |
