Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0030] The terms "first" and "second" are used for descr...

Abstract

The embodiment of the invention provides projection equipment and a control method thereof, relates to the technical field of projection, and is used for automatically correcting a to-be-projected image after the projection equipment moves so as to prevent the to-be-projected image from being mismatched with a projection screen, thereby ensuring the watching experience of a user. The projection equipment comprises a projection assembly used for projecting a to-be-projected image to a projection screen; a first distance measuring sensor used for detecting a first distance between the first distance measuring sensor and the projection screen; a second distance measuring sensor used for detecting a second distance between the second distance measuring sensor and the projection screen; a controller connected with the projection assembly, the first distance measuring sensor and the second distance measuring sensor, wherein the controller is configured to obtain a first distance and a second distance, and when the first distance is different from the initial distance and / or the second distance is different from the initial distance, and the to-be-projected image is corrected.

Description

technical field [0001] The present application relates to the field of projection technology, and in particular to a projection device and a control method thereof. Background technique [0002] With the development of electronic technology, projection equipment is used more and more widely, and its main working scenarios are teaching, demonstration, entertainment, work, etc. During daily use of the projection device, the projection device usually projects a projection image onto a matching projection screen. When the projection device is moved, the projected image will change, which will cause a mismatch between the projected image and the projected screen, affecting the viewing effect. Therefore, the existing projection equipment has a geometric correction function, which can perform geometric correction on the projected image when the projected image is shifted, so as to ensure the projection effect. [0003] However, for the existing projection device, the user can inp...
