Abstract
A system for enhanced object detection and identification is disclosed. The system provides new capabilities in object detection and identification. The system can be used with a variety of vehicles, such as autonomous cars, human-driven motor vehicles, robots, drones, and aircraft and can detect objects in adverse operating conditions such as heavy rain, snow, or sun glare. Enhanced object detection can also be used to detect objects in the environment around a stationary object. Additionally, such systems can rapidly identify and classify objects based on the encoded information in the emitted or reflected signals from the materials.
Claims20
A platform for an enhanced object detection system, comprising:
- a source of electromagnetic radiation, the source of electromagnetic radiation comprising characteristics that include at least one of a source polarization state, a source wavelength, a source phase, a source intensity, and a source direction;
- a first modulator in communication with the source of electromagnetic radiation;
- a detector module communicatively coupled to the enhanced object detection system, the detector module comprising:
- a first filter in communication with a first electromagnetic radiation detector;
- and
- a second filter in communication with a second electromagnetic radiation detector;
- and
- a computing system comprising non-transitory computer readable media and communicatively coupled to the source of electromagnetic radiation and to the detector module;
- the platform operable in a detection mode wherein:
- the source of electromagnetic radiation emits a source signal that includes at least a source polarization state and a source direction;
- the first modulator transforms the source signal into a first returned signal, wherein the first returned signal comprises a first polarization state different from the source polarization state and a first direction different from the source direction;
- the first modulator emits the first returned signal;
- the first filter transmits at least a first portion of the returned signal to the first electromagnetic radiation detector;
- and
- the second filter transmits at least a second portion of the returned signal to the second electromagnetic radiation detector;
- wherein the first portion and the second portion are different;
- and
- the computing system:
- makes a first comparison between the source signal and the first portion of returned signal;
- makes a second comparison between the source signal and the second portion of the returned signal;
- and
- uses the first comparison, and the second comparison to generate a characterization of the modification and to provide an identification of the first modulator based on the characterization.
