Title
(EN) Camera control method and display equipment
(ZH) 一种摄像头的控制方法及显示设备
Abstract
(EN) The invention discloses a camera control method and display equipment, and the method comprises the steps: enabling a controller to carry out the recognition of a specified image collected by a camera, ing a portrait region position, and calculating the azimuth distance between the region center of the portrait region position and the image center of the specified image; if the azimuth distance exceeds an azimuth set threshold, calculating a target adjustment angle of the camera according to the azimuth distance and shooting parameters of the camera; and adjusting the shooting angle of the camera based on the target adjustment angle of the camera, so as to enable the portrait of the person to be located in the central area of the specified image acquired by the camera. Visibly, according to the method and the display equipment, character position information is accurately recognized through camera image detection, the portrait position is automatically focused and positioned, the shooting angle of the camera is finely adjusted from the horizontal direction and the vertical direction, the portrait of the character is located in the center of the image shot by the camera, and therefore it is guaranteed that the character in the displayer image is centered.
(ZH) 本申请公开了一种摄像头的控制方法及显示设备,控制器对摄像头采集的指定图像进行识别处理,得到人像区域位置,计算人像区域位置的区域中心与指定图像的图像中心的方位距离;如果方位距离超过方位设定阈值,则根据方位距离和摄像头的拍摄参数,计算摄像头的目标调整角度;基于摄像头的目标调整角度,调整摄像头的拍摄角度,以使人物的人像位于摄像头采集的指定图像的中心区域。可见,本发明实施例提供的方法及显示设备,通过摄像头图像检测精准识别人物位置信息,自动聚焦定位人像位置,以对摄像头的拍摄角度从水平方向和垂直方向进行微调整,使得人物的人像处于摄像头拍摄图像的中心,从而保证显示器图像人物居中。
