Embodiment Construction

[0029] In order to make the present invention more comprehensible, preferred embodiments are described in detail as follows.

[0030] Such as figure 1 As shown, the system for automatically adjusting the flatness of the projection surface provided by the present invention is composed of an image preprocessing module, a controller, a memory, a projection module, and an image sensor. The image preprocessing module preprocesses the image, and adjusts the distortion and color of each part of the image. The controller controls the operation of the entire system, recognizes the image, corrects the image by comparing it with the standard, and controls the image preprocessing module to preprocess the image. The memory stores standard correction images. The projection module is responsible for projecting the image. The image sensor is the camera, which is used to collect the projected images and feed them back to the controller for processing.

[0031] The way the user uses it is: ...

Abstract

The invention provides a system and a method for automatically adjusting smoothness of a projection surface. The system is characterized in that the system comprises a storage unit for storing a standard corrected image; and a control unit which reads the standard corrected image from the storage unit and projects the standard corrected image on a random projection surface through a projection unit; the method comprises the steps of acquiring the corrected projection image of the standard corrected image on the projection surface through an image sensing unit; correcting the corrected projection image so that the corrected projection image is similar with the standard corrected image, thereby obtaining a correction parameter; correcting the to-be-projected image according to the correction parameter; and projecting the corrected image on the projection surface through the projection unit. The other technical solution of the invention provides a projection surface evenness automatic adjustment method based on the system. The system and the method provided by the invention can realize no distortion of the image which is projected out of the projection system without the projection surface.

Description

technical field [0001] The present invention relates to a system for enabling projected images to be correctly reflected on any projection surface and a method adopted by the system. Background technique [0002] For a projection system, the projection surface is one of the important factors that affect the projection effect. Conventional projectors, because their placement is relatively fixed, can use a retractable white curtain or a flat wall as the projection surface, so that the projected image has a better effect and is less likely to be distorted. [0003] With the rapid development of intelligent mobile terminals, mobile projection systems are born, such as mobile phone projection. For the mobile projection system, its selling point is that it is portable, so users can use it in various occasions. Therefore, the projection surface of the mobile projection system cannot always use a curtain or a flat wall, and often projects on the ground, uneven walls and other plac...
