The Panorama PTZ Camera, Also Known As The Panorama Gaze Camera
Jun 13, 2017

  The Panorama PTZ camera, also known as the Panorama Gaze Camera, is a combination of panoramic cameras and high speed dome cameras (ie, PTZ cameras), which is a high-definition network camera with both wide panoramic viewing advantages and high speed dome camera close-up gaze. Therefore, the panoramic PTZ camera with "both see wide, but also see the clear" comprehensive advantages.

  First, summary

  Panorama PTZ camera has a panoramic function, but also has a gaze function, is a panoramic camera and high speed dome camera combination.

  The panorama camera has a "wide" advantage that can be observed in a 360 degree or 180 degree field of view, but the disadvantage is that it can not be optically variable, resulting in insufficient clarity of interest to the user. On the contrary, the high speed dome camera can freely turn to the region of interest, and through the optical zoom to see the details of the region of interest, but the drawback is limited field of view, resulting in easy "Trek".

  Panorama PTZ camera combines the advantages of panoramic cameras and high-speed dome cameras and effectively overcomes their shortcomings, and thus has the advantages of a "panoramic view" of the panorama camera and the "seeable" speed of the high speed dome camera.

  Second, the working principle

  Panorama The working principle of the PTZ camera consists of two core processes, namely, calibration and linkage, as follows:

  Before the application, the relationship between the panoramic coordinate system of the panoramic camera and the polar coordinate system of the high speed dome camera is established. The process is often referred to as "point-to-surface calibration".

  In the process of application, according to the relationship between the panoramic camera and the high-speed dome camera space, the pixel coordinates of the region of interest of the panoramic picture are converted into the pitch angle and the zoom factor of the high speed dome camera, and the high speed dome camera is rotated and scaled to the corresponding The pitch angle and the zoom factor. The process is often referred to as "point-to-face linkage".
