Embodiment Construction
[0015] Such as figure 1 As shown, it is a structure diagram of a preferred embodiment of the lens shooting range determination system of the present invention.
[0016] The lens shooting range determination system 10 runs in a high-end video lens 1, which is a high-standard video lens that can be rotated left and right and adjusted up and down. The high-end video lens 1 is connected to one or more directional microphones 3 (only one is shown in the figure) through a cable 2 . When the directional microphone 3 is used by the speaker, the high-end video lens 1 is adjusted to the location of the speaker to shoot the speaker. The high-end video lens 1 can also capture the positioning point sent by the positioning device 4, and the positioning device 4 can be a remote control, a laser emitter or an infrared emitter or other devices. The high-end video camera 1 has an initial position, and after shooting all objects, the high-end video camera 1 will return to the initial position,...

A method for determining the shooting range of a lens, comprising: receiving position information of multiple positioning points sent by a positioning device; controlling the video lens to photograph each positioning point sequentially through a position adjustment module in the video lens, and obtaining the video lens when shooting each positioning point The up and down angle of vertical movement and the horizontal angle of horizontal movement, and at the same time obtain the positioning distance between each positioning point detected by the distance detection chip in the video lens and the video lens; according to the vertical angle, horizontal angle, Positioning distance and the anthropometric value corresponding to the lecturer, calculate the angle at which each lecturer needs to be rotated horizontally when the video camera is positioned; take out the horizontal rotation to the left from the angle at which each lecturer needs to rotate horizontally when the video camera is positioned The maximum angle of the camera and the maximum angle of horizontal rotation to the right determine the shooting range of the video lens. The invention also provides a lens shooting range determination system. The invention can determine the shooting range of the high-order video lens.
Description
technical field [0001] The present invention relates to a method and a system for determining a shooting range of a lens, in particular to a method and a system for determining a shooting range of a high-end video lens. Background technique [0002] Existing high-end video cameras can realize the adjustment of the up-down angle and the left-right horizontal angle, but the adjustment needs to be controlled by the remote control. The high-end video camera has a fast rotation speed (up to 300 degrees per second) and does not provide a positioning function, so when it is necessary to use the high-end video camera for shooting, it cannot provide real-time interaction. Contents of the invention [0003] In view of the above, it is necessary to provide a method for determining the shooting range of a lens to determine the shooting range of a high-end video lens. [0004] In view of the above, it is also necessary to provide a system for determining the shooting range of a lens t...
