Abstract

A method of operation of a navigation system includes: determining detected information for representing a maneuverable object detected using a device; identifying a directional portion based on the detected information for representing directional portion controlling an object travel vector of the maneuverable object; and calculating with a control circuit an estimated trajectory profile based on the directional portion for predicting movement of the maneuverable object.

First claim

What is claimed is:

1. A method of operation of a navigation system comprising:
determining detected information for representing a maneuverable object capable of self-propelled physical movement or displacement, detected using a device;
identifying a directional portion based on the detected information for representing directional portion controlling an object travel vector of the maneuverable object; and
calculating with a control circuit an estimated trajectory profile based on the directional portion for predicting movement of the maneuverable object, wherein the estimated trajectory profile includes a reference measurement, and wherein the reference measurement is calculated based on an angle relative to a surface of the maneuverable object.

2. The method as claimed in claim 1 further comprising:
determining a directional characteristic of the directional portion from the detected information; and

wherein calculating the estimated trajectory profile includes:
calculating the estimated trajectory profile based on the directional characteristic.

3. The method as claimed in claim 1 further comprising generating a motion plan profile based on the estimated trajectory profile for controlling the device in response to estimated movement of the maneuverable object.

4. The method as claimed in claim 1 wherein determining the detected information includes determining the detected information using the device corresponding to an autonomous-device status for representing the device maneuvering without real-time control from an operator.

5. The method as claimed in claim 1 wherein calculating the estimated trajectory profile includes calculating the estimated trajectory profile based on an object movement profile along with the directional portion, the object movement profile for representing movement of overall mass of the maneuverable object up to a current time.

6. The method as claimed in claim 1 wherein determining the detected information includes determining the detected information using a surroundings detector including a camera set, a distance detector, or a combination thereof of the device.

7. The method as claimed in claim 6 further comprising:
determining a directional characteristic including a wheel outline, a relative shape, a rotor magnitude, or a combination thereof of the directional portion from the detected information; and

wherein calculating the estimated trajectory profile includes:
calculating the estimated trajectory profile based on the directional characteristic.

8. The method as claimed in claim 6 further comprising generating a motion plan profile based on the estimated trajectory profile and the object movement profile along with map information.

9. The method as claimed in claim 6 further comprising:
determining a portion-movement history for tracking the directional portion over time; and
generating the object movement profile for categorizing movement of the maneuverable object.

10. The method as claimed in claim 6 further comprising:
calculating a portion change rate of the directional portion based on the detected information over time; and

wherein calculating the estimated trajectory profile includes:
calculating the estimated trajectory profile based on the portion change rate.

11. A navigation system comprising:
a control circuit configured to:
determine detected information for representing a maneuverable object capable of self-propelled physical movement or displacement, detected using a device,

a storage circuit, coupled to the control circuit, configured to store the estimated trajectory profile.

12. The system as claimed in claim 11 wherein the control circuit is configured to:
determine a directional characteristic of the directional portion from the detected information; and
calculate the estimated trajectory profile based on the directional characteristic.

13. The system as claimed in claim 11 wherein the control circuit is configured to generate a motion plan profile based on the estimated trajectory profile for controlling the device in response to estimated movement of the maneuverable object.

14. The system as claimed in claim 11 wherein the control circuit is configured to determine the detected information using the device corresponding to an autonomous-device status for representing the device maneuvering without real-time control from an operator.

15. The system as claimed in claim 11 further comprising a surroundings detector coupled to the control circuit, the surroundings detector including a camera set, a distance detector, or a combination thereof configured to determine the detected information.

16. A non-transitory computer readable medium including instructions for a navigation system comprising:
determining detected information for representing a maneuverable object capable of self-propelled physical movement or displacement, detected using a device;
identifying a directional portion based on the detected information for representing directional portion controlling an object travel vector of the maneuverable object; and
calculating an estimated trajectory profile based on the directional portion for predicting movement of the maneuverable object, wherein the estimated trajectory profile includes a reference measurement, and wherein the reference measurement is calculated based on an angle relative to a surface of the maneuverable object.

17. The non-transitory computer readable medium including the instructions as claimed in claim 16 further comprising:
