Camera- based sensors are essential contrients in robotic systems, enabling robots to perfeive their environment. A key aspect of these sensors is their field of view (FOV), which determinas he empt of te observable area. Unterstanding how to calculate and interpret thes FOV helps in designing effective robotic vision systems.

Co je to za Field of View?

Te field of view refs to to te the angular extent of the observable scéne captured by a camera sensor. It is usually expressed in differens and definites how wide the camera can see in horizontal and vertical directions. A larger FOV allows those robot to perceive more of its controundings at once.

Calculating thee Field of View

Te FOV can be calculated using the camera 's focal length and sensor size. Te basic formula for horizonthal FOV is:

CLAS1; CLAS1; CLAS3; CLAS3; FOV = 2 × arctangent (sensor width / (2 × focal length)) CLAS1; CLAS1; CLAS3; CLAS3; CLAS33; CLAS3CCAS3CLAS3CLAS3CLASPERATION;

Programové, vertical FOV uses sensor hiigt instead of width. Accurate calculations require knowing thee sensor dimensions and thee focal lens.

When selecting a camera for a robot, appror the desired FOV based on then thee application. A wide- angle lens provides a freeer view but may introde distortion. Conversely, a narrow FOV offers more detail but less coverage.
