Method and system for determining shooting range of lens

In a method for determining a field of view of a camera device, a location device sends position information to establish anchor points. The camera device captures images of the anchor points, and obtains vertical angles of the anchor points, horizontal angles of the anchor points, and distances bet...

Zusammenfassung:	In a method for determining a field of view of a camera device, a location device sends position information to establish anchor points. The camera device captures images of the anchor points, and obtains vertical angles of the anchor points, horizontal angles of the anchor points, and distances between the camera device and the anchor points. Each anchor point corresponds to one or more speakers. The method calculates rotation angles of speakers according to the vertical angles, the horizontal angles, the distances and anthropometric values of the speakers. The method further determines the field of view of the camera device according to the rotation angles.
