Abstract

The invention discloses an automatic positioning projector and an automatic positioning method. The automatic positioning projector comprises a projector body, a lens, a lens adjusting mechanism, a photosensitive sensor and a communication module, wherein the lens is arranged on the lens adjusting mechanism, and the lens adjusting mechanism is arranged on the projector body; the lens is connected to the projector body; and the photosensitive sensor is connected to the communication module, and the communication module is wirelessly connected to the projector body. According to the automatic positioning projector and the automatic positioning method, the position of the projector can be automatically calibrated without manually adjusting the projector before each use, the projector is convenient and efficient to use, and automatic positioning is accurate and simple.

Description

technical field [0001] The invention relates to a projector, in particular to an automatic positioning projector and an automatic positioning method. Background technique [0002] Today, with the popularity of projection equipment, projectors have been introduced into all walks of life, such as school classes, company meetings, project defenses, and projectors are required in various occasions. However, the current projectors do not have a self-calibration function. Every time the projector or the screen is moved, it needs to be aligned manually, and the screen often appears skewed, which is cumbersome to use. Contents of the invention [0003] In view of the existing technical defects, the present invention provides an automatic positioning projector and an automatic positioning method. The projector relies on the photosensitive sensor on the projection screen to automatically correct the position of the projector, so that the picture can be completely and clearly project...
