The embodiment of the invention provides an angle adjusting device for projection screen display equipment and the projection screen display equipment. The angle adjusting device comprises a box body, at least two telescopic adjusting mechanisms fixed in the box body, an adjusting plate which is in spherical hinge connection with the ends, away from the bottom wall of the box body, of the at least two telescopic adjusting mechanisms and can be driven by the at least two telescopic adjusting mechanisms to move within six degrees of freedom, a rotating mechanism which is fixed at the side, far away from the at least two telescopic adjusting mechanisms, of the adjusting plate, a rotating plate which is fixedly connected with the side, far away from the adjusting plate, of the rotating mechanism and is used for fixing a host of the projection screen display equipment; a camera shooting module which is fixed to the box body, comprises a camera exposed out of the surface of the box body and is used for collecting a projection screen image of the host, and a controller which is electrically connected with the at least two telescopic adjusting mechanisms, the rotating mechanism and the camera shooting module, and is used for controlling the at least two telescopic adjusting mechanisms and the rotating mechanism to act according to the screen projection image of the host to correct the host to a target placement posture.
Description
technical field [0001] The present disclosure relates to the technical field of screen projection display equipment, and in particular, to an angle adjustment device for screen projection display equipment and the screen projection display equipment. Background technique [0002] Laser TVs are widely welcomed by consumers due to their features such as high safety, large display screens and long service life. The laser TV includes a host and a screen. The laser TV emits a beam through the host, and the beam enters the human eye for imaging through the reflection of the screen. Since the placement angle of the host can be flexibly set, when the placement angle of the host changes, the image displayed on the screen will be tilted. In the related art, whenever the image is tilted, the user needs to manually adjust the placement angle of the host, and the adjustment process is cumbersome and time-consuming. Contents of the invention [0003] The purpose of the embodiments of ...
