a)

Imaginea camera whose configuration is as follows:

An object at a distance of 1m from the pupil of the camera is focused on a camera sensor at a distance of 1cm from the pupil of the camera.
If we assume that the camera lens is very thin, then what is the focal length of the lens ([75% of this question mark])? What would be the size of a 1.6m-tall in- focus object on the camera sensor ([25% of this question mark])? Show your work.                                  [10 marks]

c) 计算机视觉和成像代写

Apple’s iPhone and iPad implement Face ID, a face recognition system. The FaceID system uses a structured light-based camera to collect depth information and integrates it with a 2D image collected from the front camera to build the complete 3D image.

i. Explain how the structured light-depth imaging works [20% of this questionmark]

ii. Among the various depth measuring techniques taught, suggest why Applechose the structured light camera for use on mobile devices. List at least four required conditions for the depth imaging camera to be used on mobile devices for Face ID. Describe which features of the structured light method is more suitable for each of the listed conditions by comparing them with the other  [80% of this question mark]                                  [10 marks] 

 

d)  计算机视觉和成像代写

Arobot is put into the nuclear power plant accident site with a mission of cleaning the area, which is too dangerous for  The site is severely contaminated with radiation which limits communication and means that the robot must act semi- autonomously.

i. As time goes on, the strong radiation causes the failure of individual camerasensor pixels randomly. These pixels are either stuck in the off (black) state or the on (white) state. Give three image noise removal methods. Select one of these methods to use in this situation, and explain why it is most appropriate  [20% of this question mark]  计算机视觉和成像代写

ii. Therobot will navigate using knowledge of the edges of the walls, floor, and  Describe and explain the steps in the Canny edge detection algorithm. Explain why it is useful to apply the Hough transform to the output of the Canny edge detection algorithm. [40% of this question mark]

iii. In addition to the cleaning, the robot has another mission which is finding aspecific object. The robot has an image of the target object that it must  What are the challenges involved in this mission? Design and explain a process by which it can find the object autonomously. Justify the purpose and importance of each step. [40% of this question mark]                                  [20 marks]
