Concept
Carbon capture and storage (CCS) is a technology aimed at reducing greenhouse gas emissions by capturing carbon dioxide (CO2) from sources like power plants and storing it underground to prevent it from entering the atmosphere. It is considered a critical tool in the global effort to mitigate climate change, especially in industries that are hard to decarbonize.
Relevant Fields:
Concept
Homogeneous coordinates are a system used in projective geometry to represent points in space, allowing for the representation of points at infinity and facilitating transformations such as translation, rotation, and scaling within a single mathematical framework. By adding an extra dimension, Homogeneous coordinates enable the use of matrix operations for geometric transformations, making them essential in computer graphics and vision applications.
Concept
Intrinsic parameters are the internal characteristics of a camera that affect how images are captured, such as focal length, optical center, and lens distortion. These parameters are crucial for tasks like camera calibration and 3D reconstruction, as they help in accurately mapping the 3D world onto a 2D image plane.
Concept
Extrinsic parameters are used in computer vision to describe the position and orientation of a camera in relation to a world coordinate system. They are crucial for tasks such as 3D reconstruction and scene understanding, as they allow for the transformation of points from the world coordinate system to the camera coordinate system.
Concept
Perspective projection is a technique used in computer graphics and art to simulate the way objects appear smaller as they get further away from the viewer, mimicking human eye perception. It is crucial for creating realistic three-dimensional scenes on two-dimensional surfaces, as it maintains the depth and scale of objects relative to the viewer's point of view.
Concept
The image plane is a virtual two-dimensional surface where a camera or imaging system focuses light to form an image, typically located at the sensor or film in a camera. It is crucial in determining the field of view and the quality of the captured image, as any misalignment or distortion can lead to image aberrations or blurriness.
Concept
The optical center of a lens or optical system is the point where light rays entering the lens parallel to the optical axis converge after refraction. It is a critical reference point in optics, often used in the design and alignment of lenses and optical instruments to ensure accurate image formation.
Concept
Camera calibration is the process of estimating the parameters of a camera to correct distortions and achieve accurate image measurements. It involves determining the intrinsic and extrinsic parameters of the camera to map the 3D world onto a 2D image plane accurately.
Concept
A rotation matrix is a mathematical tool used to perform a rotation in Euclidean space, preserving the object's size and shape while changing its orientation. It is an orthogonal matrix with a determinant of 1, ensuring that the transformation is both linear and reversible.
Concept
A translation vector is a mathematical tool used to move every point of a shape or object in a specific direction and distance within a coordinate system, without altering its orientation or size. It is fundamental in fields like geometry, physics, and computer graphics for operations involving shifting objects in space.
Concept
The World Coordinate System (WCS) is a standardized framework used in computer graphics and geographic information systems to represent the spatial location of objects in a three-dimensional environment. It provides a universal reference for positioning and orienting objects, facilitating interoperability and consistency across different systems and applications.
Concept
The Model-View Matrix is a crucial component in computer graphics that combines model transformations and view transformations into a single matrix, enabling the efficient rendering of 3D scenes onto a 2D screen. It allows for the positioning and orientation of objects in a scene relative to a camera's viewpoint, facilitating the seamless transition from object space to camera space.
