1. What is Machine Vision? - ANSWER ✓ It is the automatic
acquisition and analysis of images to obtain desired data for
controlling or evaluating a specific part or activity
2. List some roles of the camera in a MV system - ANSWER ✓
Provide a physical enclosure with precise mounting and of the
sensor(s) and an appropriate lens mount precisely aligned to the
sensor
3. Provide the electronics that power, control, and interface with the
imaging sensor(s) to create an image and read‐ out the pixel values
4. Provide additional electronics to transfer the image to, and
communicate other data and signals with, a processor
5. Implement features that may be available on the sensor
6. Furnish convenient access from external devices via suitable
connections, and provide physical mounts for ease of integration
with and external structure
7. True/False - The numeric value of data relative to the sensor is
dependent on the final use of the image after processing. -
ANSWER ✓ FALSE:
, 8. regardless of the final use of the image after processing, the
numeric value of data relative to the sensor is always a single
number representing the amount of EM energy collected by that
pixel over a specific exposure duration.
9. How do filters work {to create a color image}?
10. (Bayer Pattern Filter) - ANSWER ✓ Incoming visible
illumination is filtered to allow only a specific broad color range
through to each pixel.
11. Each pixel contains a numeric value for that color range.
12. What is "de-Bayering"?
13. (also, describe how it works) - ANSWER ✓ A process in
which viewable images can be made from the data.
14. Neighboring pixels are processed ("de‐Bayering") and
combined so that each pixel has a calculated R, G, B value -
creating a color image.
15. True/False - Non‐visible imaging (Infrared ‐ IR) is NOT a
part of the electromagnetic spectrum. - ANSWER ✓ FALSE
16. see wavelength (EM) chart
17. What is the key difference for non‐visible imaging (Infrared ‐
IR) with regards to the SENSOR? - ANSWER ✓ These styles of
sensors are made with different types of material vs. standard
visible range sensors which use silicon.
18. TRUE/FALSE
