Abstract
A method of navigating an autonomous vehicle includes receiving pulsed illumination from an object in the vehicle environment and decoding the pulsed illumination. The object is identified using the decoded pulsed illumination of the pulsed illumination, and the autonomous vehicle navigated through the vehicle environment based on the identification of the object. Obstacle avoidance methods and navigation systems for autonomous vehicles are also described.
Claims19
A method of navigating an autonomous vehicle, comprising:
- receiving pulsed illumination from an object in the vehicle environment;
- generating pulse data from the pulsed illumination;
- decoding the pulse data;
- identifying the object using the decoded pulsed illumination;
- receiving non-pulsed illumination from the vehicle environment;
- generating image data of the vehicle environment using the non-pulsed illumination, wherein the image data is generated coincidentally with the pulse data;
- and
- navigating the autonomous vehicle through the vehicle environment based on the identification of the object.
A method of controlling an autonomous vehicle, comprising:
- receiving non-pulsed illumination from the vehicle environment;
- generating image data of the vehicle environment using the non-pulsed illumination;
- receiving pulsed illumination from an object in the vehicle environment, wherein the pulsed illumination and non-pulsed illumination are in a common visible, short-wavelength infrared, a mid-wavelength infrared, or long-wavelength infrared waveband;
- generating pulse data from the pulsed illumination, wherein the image data is generated coincidentally with the pulse data;
- decoding the pulse data;
- identifying the object using frequency of the decoded pulsed illumination, wherein identifying the object includes selecting an identity associated with the object based on the decoded pulsed illumination;
- enhancing the image data by inserting the object identity into the image data;
- analyzing the enhanced image data with a machine vision algorithm;
- and
- navigating the autonomous vehicle through the vehicle environment based on the identification of the object.
A navigation system for navigating an autonomous vehicle through an external vehicle environment having objects external to the autonomous vehicle, comprising:
- a sensor for receiving pulsed illumination from the object the in vehicle environment and generating pulse data and for receiving non-pulsed illumination from the vehicle environment and generating image data, wherein the image data is generated coincidentally with the pulse data;
- a decoder in communication with the sensor for decoding the pulse data;
- an object identifier in communication with the decoder for identifying the object using the decoded pulsed illumination;
- and
- a controller in communication with the object identifier and operatively connected to the autonomous vehicle for navigating the autonomous vehicle through the vehicle environment based on the identification of the object.
