Which wearable sensor could provide data to estimate the rumination time in cattle?
Accelerometer (or a dedicated rumination sensor).
What type of behavioral information can be derived from analyzing accelerometer data? Mention at least one specific phenotype.
Standing time, lying time, standing bouts, rumination time, feeding time, ...
How could you estimate bodyweight or body condition score without direct physical contact with the animal?
3D/depth cameras
In a depth camera, each pixel stores what information?
Distance of the object from the camera
What type of sensor commonly mounted on drones can capture information about vegetation health through different light wavelengths?
Multispectral or hyperspectral cameras
How does GreenFeed try to keep the animal engaged?
Rewards/pellets
Under what circumstances it could make sense to use a leg band rather than a collar?
When monitoring strictly behavioral monitoring
What determines how we see the color of an object?
Absorbed and reflected wavelengths
Mention one limitation of RGB.
Lighting
What type of drone typically allows for vertical takeoff and landing?

What type of drone is capable of hovering and carrying payload?
Multirotor/hexacopter/quadcopter.
What type of positive reinforcement do cows receive when trained to use virtual fencing collars?
Mineral lick or portable trough (with rewards)
When could you potentially need to use both UWB and GPS?
If tracking location is really important for animals that move between indoor and outdoor spaces.
Name at least 2 types of computer vision tasks
Image classification, object detection, instance segmentation, keypoint detection, ...
In the infrared spectrum we have night vision (near infrared), thermal vision (far infrared), and what other type of imaging?
hyper/multi-spectral
What is a fixed-wing drone better at compared to multirotor?
Covering long distances (efficiency).
What component in an RGB camera is analogous to the photoreceptor cells in the human eye and is arranged in a specific color pattern?
Accepted answers: bayer filter and photodiodes
