Question 1

Which lighting method has most of the light from the light source reflected away from the camera,with the light usually at an angle of less than 45 degrees or focused off the object?
A) Structured lighting
B) Backlighting
C) Dark field lighting
D) Diffuse dome lighting

Accepted Answer

Dark field lighting is characterized by most of the light being reflected away from the camera, often used at angles less than 45 degrees or focused off the object to enhance edge contrast or surface defects.

Question 2

Which part recognition method sorts data by finding elements that have similar values and grows outward from there?
A) Edge detection
B) Template matching
C) Clustering
D) Algorithm method

Accepted Answer

Clustering is the method that sorts data by finding elements that have similar values and grows outward from there, grouping data points into clusters based on similarity.

Question 3

Which part of the camera focuses the incoming light directly on the CCD or CMOS elements of the camera?
A) Imaging device
B) Processor
C) Lens
D) Light source

Accepted Answer

The lens of the camera is responsible for focusing the incoming light directly onto the CCD (Charge-Coupled Device) or CMOS (Complementary Metal-Oxide-Semiconductor) sensor elements, which are the imaging devices that capture the visual information.

Question 4

Accepted Answer

The answer of How can we take measurements using a...

Question 5

Which lighting system uses one or two light sources set at a greater-than-45 degree angle to the object so that most of the light transmitted is reflected into the camera lens?
A) Partial bright field lighting
B) Full bright field lighting
C) Axial diffuse lighting
D) Diffuse dome lighting

Accepted Answer

Partial bright field lighting is characterized by one or two light sources positioned at an angle greater than 45 degrees relative to the object, ensuring that a significant portion of the light is reflected directly into the camera lens, which is ideal for highlighting surface irregularities or features.

Question 6

The first camera type device was the ___________________.
A) daguerreotype camera
B) pinhole camera
C) CRT
D) image dissector

Accepted Answer

The first camera type device was the pinhole camera, an early form of camera where light passes through a small hole to project an inverted image on the opposite side. This principle has been known and used for centuries, predating more complex camera designs.

Question 7

Which of the following lighting types might explode if you touch the bulb?
A) Incandescent
B) Halogen
C) High-intensity discharge
D) Xenon

Accepted Answer

Halogen bulbs can explode if touched because the oils from your skin can create hot spots on the bulb, leading to uneven heating and potential explosion.

Question 8

Who invented the CCD,which was made up of pixels constructed of metal oxide semiconductor capacitors?
A) C.T.Sah and Frank Wanlass
B) James J.Gibson
C) Willard S.Boyle and George E.Smith
D) Larry Roberts

Accepted Answer

Willard S. Boyle and George E. Smith invented the Charge-Coupled Device (CCD), which is an important technology used in digital imaging.

Question 9

Who created the first industrial optical character recognition system?
A) Bryce E.Bayer
B) Robert J.Shillman
C) Thomas B.McCord and James A.Westphal
D) Stanley R.Sternberg

Accepted Answer

Robert J. Shillman is the founder of Cognex Corporation, which is known for creating the first industrial optical character recognition (OCR) system.

Question 10

Which of the following lighting types consists of a special type of semiconductor that emits light when current is applied via energy released as photons when electrons cross the boundary from between the n-type and p-type materials?
A) Xenon
B) Fluorescent
C) LED
D) Laser

Accepted Answer

LED (Light Emitting Diode) is a semiconductor device that emits light when an electric current passes through it, due to the recombination of electrons and holes at the junction of n-type and p-type materials, releasing energy in the form of photons.

Question 11

Which part recognition method sorts data by using a specific mathematical formula to analyze the sample part and then compare newly processed image data to this initial calculation result?
A) Edge detection
B) Template matching
C) Clustering
D) Algorithm method

Accepted Answer

The algorithm method involves using a specific mathematical formula to analyze and compare image data, which aligns with the description given.

Question 12

Which lighting system is good at looking for missing material?
A) Partial bright field lighting
B) Full bright field lighting
C) Axial diffuse lighting
D) Diffuse dome lighting

Accepted Answer

Axial diffuse lighting is effective for detecting missing material on surfaces because it provides even illumination, reducing shadows and reflections that can obscure details. This makes it easier to spot inconsistencies or missing parts.

Question 13

What is the difference between line scanning and area scanning?

Accepted Answer

The answer of What is the difference between line scanning...

Question 14

Which lighting method has a light source placed inside the surface of a partially reflective dome,with the camera focused on the object through a hole in the middle?
A) Structured lighting
B) Backlighting
C) Dark field lighting
D) Diffuse dome lighting

Accepted Answer

Diffuse dome lighting involves placing the light source inside a partially reflective dome, with the camera focusing on the object through a hole in the middle. This setup is designed to provide even, soft lighting that minimizes shadows and reflections, making it ideal for imaging objects with complex surfaces.

Question 15

Which part of the vision system takes the raw data from the sensors and converts it into a digital signal that other controllers can use one frame or picture at a time?
A) Imaging device
B) Processor
C) Lens
D) Communication

Accepted Answer

The processor takes the raw data from the sensors and converts it into a digital signal that other controllers can use one frame or picture at a time.
