Robotic vehicle grass structure detection

A robotic vehicle, comprising:

• a sensor network comprising one or more sensors configured to detect conditions proximate to the robotic vehicle;
• a detection module configured to detect objects proximate to the robotic vehicle using contact-less detection, and
• processing circuitry configured for:
• receiving image data and corresponding position data captured by a robotic vehicle traversing a parcel;
• comparing the image data with parameters known to identify grass;
• and
• classifying the image data as grass when the image data meets the parameters known to identify grass,
• wherein comparing the image data with parameters known to identify grass comprises:
• transforming the image data from the spatial domain to the frequency domain;
• performing low pass or high pass filtering on the image data;
• and
• transforming the image data back into the spatial domain.
