Description: As shown in the attached illustrations and described below, an integrated hardware and software system that combines data from sensors recording position, orientation, distance to ground (rangefinder) and light reflectance (including vision), is disclosed. Sprays inducing fluorescence or other sensibility‐augmenting behaviors may be used.
A combination of distance (rangefinder) sensors, position sensors, orientation sensors and spatial light reflectance sensors are placed as a single unit on farm machinery to collect data useful for farm field evaluation or for control of farm equipment. Specifically, rangefinder sensors may be used to measure surface geometrical profile and light reflectance sensors may be used to segment surface into soil, crop residue and live plants. The fusion of these sensors enables a better understanding of farm implement performance or field health. The sensors can be made as a cluster independent of any specific piece of farming equipment. Data collected is shown graphically as colored maps of field where color indicates the magnitude of a value of interest. In this case a rangefinder sensor can scan the surface and generate data useful for calculating a roughness index. Data from a light reflectance sensor can be used to segment an area of soil surface into crop residue and exposed soil, the percentage of residue cover can then be calculated.
Data collected relating to soil sensor fusion of soil/crop residue and roughness index is processed and interpreted into agriculturally‐relevant values that are displayed graphically and in table form or used for automatic control.
