120 Coreel technologies Interview Questions and Answers

20 common asked question in every interview

Ques:- What is bundle adjustment? When is it used in 3D reconstruction?

Asked In :- Hidden Brains InfoTech, Lucid Imaging, Creative Capsule, LLC, SPB, Christie Digital, Amagi Media, ProtoTech Solutions, Juego Studio, Cadmaxx Solutions, Vconstruct (India),

Right Answer:
Bundle adjustment is an optimization technique used in 3D reconstruction to refine the 3D coordinates of points and the camera parameters simultaneously. It minimizes the re-projection error between observed image points and projected 3D points, ensuring a more accurate and consistent 3D model. It is typically used after initial structure-from-motion processes to improve the quality of the reconstruction.

Ques:- Explain disparity and how it’s related to depth.

Asked In :- Appiness Interactive, Creative Capsule, LLC, Agi Glaspac, Lenskart Solutions, Wildcraft, ProtoTech Solutions, Juego Studio, Bentley Motors, Smart TV Broadcasting, Tekno Point Multimedia,

Right Answer:
Disparity refers to the difference in the position of an object in the left and right images captured by our two eyes. It is related to depth because greater disparity indicates that an object is closer to the observer, while smaller disparity suggests that the object is farther away.

Ques:- What is 3D vision and how is it different from 2D computer vision?

Asked In :- Hidden Brains InfoTech, Appiness Interactive, Muvi Entertainment, IMAGINATION TECHNOLOGIES LIMITED, AroDek, SPB, Dassault Systemes, Wildcraft, Vconstruct (India), Mechlin Technologies,

Right Answer:
3D vision refers to the ability of a system to perceive depth and spatial relationships in a three-dimensional space, allowing it to understand the shape, size, and position of objects. In contrast, 2D computer vision processes images as flat, two-dimensional representations, lacking depth information.

Ques:- What is epipolar geometry? Why is it important in stereo vision?

Asked In :- AroDek, Lucid Imaging, INNOART TECHNOLOGIES, Agi Glaspac, B Braun, SPB, ProtoTech Solutions, ARI Simulation, Vconstruct (India), Gameopedia,

Right Answer:
Epipolar geometry is the geometric relationship between two views of the same scene captured by two cameras. It defines the epipolar plane, epipoles, and epipolar lines, which help in constraining the search for corresponding points in stereo images. It is important in stereo vision because it reduces the 2D correspondence problem to a 1D search along epipolar lines, making it easier and more efficient to find matching points between the two images.

Ques:- How does SLAM (Simultaneous Localization and Mapping) work in 3D vision systems?

Asked In :- AroDek, Lucid Imaging, ANSYS Software, Graebert India Software, Agi Glaspac, B Braun, Dassault Systemes, TATA Advanced Materials, AMI Tech India, Cadmaxx Solutions,

Right Answer:
SLAM (Simultaneous Localization and Mapping) in 3D vision systems works by using sensors to gather data about the environment while simultaneously tracking the position of the sensor itself. It creates a map of the surroundings by identifying features in the 3D space, such as points, lines, or surfaces, and updates the sensor's location based on the movement and changes in the environment. This process involves algorithms that fuse data from various sources, like cameras and LiDAR, to ensure accurate mapping and localization in real-time.

Graphic Design

Ques:- Explain about Lasso tools in Photoshop?

Asked In :- iB Arts Pvt. ltd, AroDek, Lucid Software, Creative Capsule, LLC, CAP Digisoft Solutions, Befree, Innodata, SDL, Conde Nast, Siam Computing,

Right Answer:
The Lasso Tool in Photoshop is used for making freehand selections. It allows you to draw a selection around an area of an image by clicking and dragging the cursor. There are three types of Lasso Tools: the standard Lasso Tool for freehand selections, the Polygonal Lasso Tool for straight-edged selections, and the Magnetic Lasso Tool that automatically snaps to the edges of objects in the image.
