Publication number: 20220180282Abstract: Systems, methods, and apparatuses for worksite equipment path planning is provided. An example system may include an autonomous vehicle configured to operate a camera and position sensor to capture image data associated with a worksite. The system may also include a worksite analysis engine comprising processing circuitry configured to receive the image data of the worksite captured by the autonomous vehicle and generate a virtual layout of the worksite based on the image data. The worksite analysis engine may also receive equipment data and crew data, and generate a workflow based on the virtual layout, the equipment data, and the crew data. The workflow may include workflow assignments for each crew member at the worksite, each workflow assignment indicating a task, equipment to perform the task, and an equipment path for the task.Type: ApplicationFiled: October 21, 2019Publication date: June 9, 2022Inventors: Eric Powell, Brad Graham, Dale Barlow, Frank Peters, Scott Andermann
