A device for adjusting the camera angle of a physical projector

Abstract

The invention discloses a device for adjusting the angle of a camera of a real object projector. A clamping cavity of a clamping apparatus is used for clamping the top of an arm lever of the real object projector; a steering engine is fixed at the root segment of the clamping apparatus at the upper part of the clamping cavity; a rotating shaft of the steering engine is connected with a driving gear; the driving gear is meshed with a driven gear under the driving gear; the right lower end of a Z-shaped rod is sleeved with the left half part of an axle center hole in the driven gear; the left upper end of the Z-shaped rod is fixedly connected with the right side of a slide track; the right half part of the axle center hole in the driven gear is fixedly connected with the left end part of a short horizontal rod; the right end part of the short horizontal rod is fixedly connected with the middle of a vertical rod; the center line of a hinge shaft between the camera of the real object projector and the arm lever is reclosed with the axis of the right lower end of the Z-shaped rod; the upper end part of the vertical rod is fixedly connected with the bottom of a slide block; the lower end part is fixedly connected with a balance weight; a horizontal rod is sleeved with a horizontal through hole of the slide block; the left end part of the horizontal rod is fixedly connected with a fixing frame; the camera is sleeved with the fixing frame; bolts tightly propping the camera are arranged on the fixing frame; the angle signal input end of the steering engine is connected with the angle signal output end of a steering engine controller.

Description

technical field [0001] The invention relates to a device for adjusting the camera angle of a physical projector. Background technique [0002] Physical projectors are widely used in business presentations and teaching presentations. It includes parts such as a camera, a boom and a demonstration platform, and the camera is hinged with the boom, and the boom is hinged with the demonstration platform. During the demonstration, the object to be displayed is placed on the demonstration platform, and the hinge angle between the camera and the arm is manually adjusted to make the camera rotate in a plane perpendicular to the demonstration platform. Aim the camera at the displayed object, and transmit the captured image signal of the displayed object to the display device for output. The existing problem is that the hinge angle between the camera and the arm can only be adjusted manually, which is inconvenient to operate and low in efficiency. In particular, when the physical pro...

Problems solved by technology

The problem is that the hinge angle between the camera and the arm can only be adjusted manually, which is inconvenient to operate and low in efficiency

In particular, when the physical projector is used to read the view of the displayed object at a specific angle or read the details of the displayed object at a specific angle such as the scale of the experimental instrument, the camera needs to be aligned with the displayed object at a precise angle, and it is difficult to adjust it manually. Control the angle of the camera to affect the demonstration and teaching effect
