US 2021/0004609 A1 · OBJECT RECOGNITION BY FAR INFRARED CAMERA

Abstract

Example implementations described herein are directed to integration of far infrared cameras in a vehicle system to detect objects based on relative temperature of objects. Such implementations can improve accuracy when paired, for example, with classification systems that classify objects based on the shape of the object, as both the shape and relative temperature can be used to ensure that the classification is accurate. Further, example implementations can synchronize far infrared cameras with other sensor systems to determine distance, energy, and absolute temperature of an object, which can also be used to enhance classification. Such classifications can then be provided to an advanced driver assistance systems (ADAS), which can control the vehicle system in accordance with the object classification.

Claims15

Dependent claims

A vehicle system, comprising:

one or more far infrared (FIR) cameras;
and
a processor, configured to:
classify a first object detected from one or more images of the one or more FIR cameras;
and
for a second object detected from the one or more images of the one or more FIR cameras having a relative temperature range coinciding with the first object, recognize the second object as having the classification of the first object.

3 more elements

A non-transitory computer readable medium, storing instructions for executing a process for a vehicle system comprising one or more far infrared (FIR) cameras, the instructions comprising:

classifying a first object detected from one or more images of the one or more FIR cameras;
and
for a second object detected from the one or more images of the one or more FIR cameras having a relative temperature range coinciding with the first object, recognizing the second object as having the classification of the first object.

Dependencies are inferred from the claim text.
