Title: Worksite Soil Volume Sensing
Brief Description of the Drawings: Figure 1 is a block diagram illustrating a worksite soil volume sensor.
Description: As shown in the attached illustration and described below, a soil volume sensing system that
applies surface attribute corrections to a surface measurement in order to provide for a more accurate soil volume measurement, is disclosed.
Profitability in the earth moving business requires an accurate map of the terrain. Data from aerial images (such as data gathered with UAVs) provide an opportunity for fast, inexpensive, accurate 3D worksite mapping. However, worksite surface measurement, and consequently soil volume measurement, accuracy may suffer from vegetation and other surface cover which occludes the true soil surface.
The problem of worksite soil volume measurement accuracy is solved by classifying the worksite surface based on at least one surface attribute and then applying a correction to the surface measurement based on the classification. The corrected surface measurement may then be used to control a soil moving machine to relocate soil based on the corrected surface measurement and a target surface value.
This disclosure relates to a computer‐implemented method of measuring a soil surface comprising:
Receiving georeferenced ground surface data for a processor from an aerial source [UAS] [opportunity for partitioning the processing workload between UAS and ground station]
Dividing and classifying the a worksite into multiple worksite sub‐regions based on at least one attribute of the received ground surface data
Creating a georeferenced soil surface map for each worksite sub‐region based on the georeferenced ground surface data and the classification of the worksite sub‐region
The method of measuring a soil surface as described above and further providing an estimated error and/or conf...
