OAK Thermal

The OAK-T (OAK Thermal) is our first camera with a thermal sensor and a color image sensor.

When fusing thermal frames, color frames, and AI models, you can create a wide variety of applications in different fields, such as:

• Agriculture: Health crop, detect irrigation issues, detect pests, livestock health monitoring, etc.
• Industrial: Detect overheating, detect leaks, detect fires, etc.
• Security: Detect intruders (night vision), detect fires, etc.
• Transportation: Detect pedestrians, vehicles, bicycles for analytics and traffic optimization.

It leverages our OAK-SoM-Pro to make an overall compact design. The use of the SoM reduces the design's scale, making it easier to mount or fit anywhere seamlessly. The design will also be open-source when we verify the hardware design.

• IMU: BMI270
• Dimension: 80x52x46mm
• Weight: 297g (with enclosure)

Thermal perception: 

Thermal cameras detect infrared radiation, which is emitted by all objects based on their temperature. We use a special IR-capable lens to focus the infrared light emitted by all of the objects/scene in view, which is then scanned by an array of infrared-detector elements ("pixels") in the camera.

Power consumption:

Most of the power is consumed by the RVC2, so the power consumption mostly depends on the workload of the chip:

• Base consumption + PoE circuitry + camera streaming: 3W - 3.5W
• Thermal sensor: ≤1W
• AI subsystem consumption: ≤1W
• Stereo depth pipeline subsystem: ≤0.5W
• Video Encoder subsystem: ≤0.5W

The total power consumption can be ≤ ~6.5W if you are using all the features at 100% at the same time. To reduce the power consumption,
you can reduce FPS of the whole pipeline - that way, subsystems won't be utilized at 100% and will consume less power.
