Abstract

The invention relates to a projector automation trapezoid correction system. The system comprises a projector shell, a PCB, a switch component, a gyroscope sensor, a main chip, a register chip, a display screen and a projector lens. The projector shell is horizontally arranged. The PCB is arranged on a bottom end surface of the projector shell. The projector lens is arranged on one side of the projector shell in an embedded mode. The gyroscope sensor, the main chip, the register chip and the display screen are successively arranged on the PCB. The switch component is arranged at an inner corner of the projector shell. The switch component is arranged on the PCB. By using the projector automation trapezoid correction system, a projector trapezoid distortion phenomenon can be rapidly adjusted and usage and maintenance cost is reduced so that an application of the projector is humanized and idealized.

Description

technical field [0001] The invention relates to the technical field of correction systems, in particular to an automatic keystone correction system for projectors. Background technique [0002] As a large-screen technology, projectors are widely used in concerts, business, conferences, home theaters, etc. A projector is a precision instrument that integrates optical, mechanical, and electrical complex systems. In the process of use, the screen often fails to achieve the desired effect due to improper operation by the operator. The structure of the projector is complicated, and it needs professionals to carry out the general installation and debugging. It is very inconvenient to operate and cannot be widely used. When using a projector, its horizontal and vertical directions need to be perpendicular to the screen in order to project a completely normal image. But in the actual use process, the left and right directions are relatively easy to meet the requirements, but in t...
