For a large camera, the camera angle needs to be set during installation. Therefore, the large camera is usually installed on a bracket that can adjust the camera camera angle.

如图1所示，现有大型摄像机多采用如图所示的安装支架进行安装角度的调节。其中，安装支架的底座01固定在龙门架或其他安装支撑面上，垂直调节板02上安装摄像机。水平调节板03通过左右两套水平转轴和水平固定螺钉与底座01的弧形孔连接；垂直调节板02通过左右两套垂直转轴和垂直固定螺钉与水平调节板的弧形孔连接。As shown in FIG. 1 , most existing large-scale cameras use the installation bracket as shown in the figure to adjust the installation angle. Wherein, the base 01 of the installation bracket is fixed on the gantry or other installation support surface, and the camera is installed on the vertical adjustment plate 02 . The horizontal adjustment plate 03 is connected with the arc-shaped hole of the base 01 through two sets of left and right horizontal shafts and horizontal fixing screws; the vertical adjustment plate 02 is connected with the arc-shaped hole of the horizontal adjustment plate through two sets of left and right vertical shafts and vertical fixing screws.

调节方式：调节水平角度时，需要分别旋松两侧的水平固定螺钉，然后调整角度，角度调节完成后再旋紧两颗水平固定螺钉，同理，调节垂直角度时，也需要分别旋松两侧的垂直固定螺钉。Adjustment method: When adjusting the horizontal angle, you need to loosen the horizontal fixing screws on both sides respectively, and then adjust the angle. After the angle adjustment is completed, tighten the two horizontal fixing screws. Similarly, when adjusting the vertical angle, you also need to loosen the two horizontal fixing screws respectively. side vertical set screw.

现有技术中，调节摄像机摄像角度时，水平调节板和垂直调节板均需要调节两侧的螺钉，即需要调节摄像机安装支架周侧四个方向的螺钉，因此，在调节时，操作人员需要调整自己与调节摄像机安装支架的位置关系，对于大型的摄像机来讲，操作人员的操作不方便，有些高空作业的场景，施工难度更大。In the prior art, when adjusting the shooting angle of the camera, both the horizontal adjustment plate and the vertical adjustment plate need to adjust the screws on both sides, that is, the screws in four directions around the camera mounting bracket need to be adjusted. Therefore, when adjusting, the operator needs to adjust It is inconvenient for operators to operate large-scale cameras, and the construction is more difficult in some scenes of high-altitude operations.
