Problems solved by technology

However, manual operation is very inconvenient, especially when the projector is placed incorrectly and unstable. After the manual adjustment is completed, the original adjustment will be invalidated if the projector is moved again, and manual adjustment is required again; With the increase of the use time of the instrument, the failure of the buttons, or the loss of the remote control and other accidents will lead to the inability to adjust, which will bring certain troubles to the user.

Embodiment Construction

[0014] see figure 1 , figure 1 It is a flow chart of the method for correcting the image distortion of the projector of the present invention.

[0015] The projector image distortion correction method includes the following innovative technologies: spatial three-axis positioning sensing, spatial three-axis data processing and spatial three-axis direction control. Specifically include the following steps:

[0016] Step S101, obtaining the position data of the projector relative to the three-axis space from the three-axis space positioning device provided on the projector;

[0017] The positioning of the projector relative to the three-axis space is obtained through a three-axis positioning device. This sensing device is essentially a sensor. The sensitive elements in it convert the three-axis positioning signal of the projector into a corresponding electrical signal, and enter the preamplifier circuit. After the signal is improved by the signal conditioning circuit, Analog-...

Abstract

The invention provides a method and a system for correcting a distorted projector image and a projector. The method comprises the following steps of: acquiring position data of the projector relative to a triaxial space from a locating device of the triaxial space arranged on the projector after the projector is switched on; comparing the detected position data with reference position data and acquiring position offset of the projector; calculating an adjustment position and an adjustment angle of a trapezoid optical correction device of the projector according to the position offset; and regulating the trapezoid optical correction device according to results. By the method and the system for correcting the distorted projector image and the projector, the distorted image caused by the position offset of the projector can be automatically, conveniently and accurately corrected.

Description

technical field [0001] The invention relates to the technical field of image distortion correction of projectors, in particular to a projector image distortion correction method and system thereof, and a projector with the image distortion correction system. Background technique [0002] At present, there are usually two methods for trapezoidal correction of known projectors: optical trapezoidal correction and digital keystone correction. For the purpose of digital keystone correction, another kind of digital keystone correction is to achieve keystone correction through software. Relatively speaking, optical keystone correction is widely used. [0003] In a projector that uses optical keystone correction, whether it is an LCD (liquid crystal) projector or a DLP (rear projection) projector, the optical keystone correction of the projector is adjusted by manually operating the buttons on the projector casing or the remote control. device, thereby correcting the conical light ...
