Problems solved by technology

When playing stereoscopic images in 3D mode, if you only switch to 2D mode from the hardware in real time, and only play stereoscopic images in 2D mode, it will not have a clear effect; Switch to 3D mode in real time from the hardware, just play flat images in 3D mode, and there will be no stereoscopic effect

Embodiment Construction

[0021] The present invention will be further described below in conjunction with drawings and embodiments.

[0022] Use DirectShow technology to build a Filter Graph that can play ordinary files, change the processing process of image data according to the display mode of the stereoscopic display device, perform 2D or 3D processing on the decoded original video image in the Filter Graph, and then submit it to Display device display. The specific implementation has the following steps:

[0023] Step 1. Build 2D Filter and 3D Filter

[0024] Switching between 2D and 3D is essentially to display different image content on the display device. The original image data needs to be processed in different ways inside the Filter Graph, and then submitted to the display device for display. This requires the construction of the 2D Filter required for the 2D display mode and the 3D Filter required for the 3D display mode. 2DFilter function: perform data processing on each frame of origi...

Abstract

The invention relates to a 2D and 3D software switching method based on DirectShow technology, comprising the following steps of: constructing 2D Filter and 3D Filter, establishing a link capable of playing back common video files by DirectShow technology in order to construct a complete broadcast link that is adaptive to the current display mode, processing content of each frame got through decoding a resource file before submitting an image to display according the display mode of a display device, submitting the generated data to the display device to display, and switching 2D and 3D in software corresponding to the switching in hardware. The method has the advantages that plane images or stereo images can be adjusted in real time in software according to the display mode, 2D and 3D can be switched quickly and in real time without being re-broadcast, and effects of 2D and 3D can be conveniently compared.

Description

technical field [0001] The invention relates to a method for switching between 2D and 3D software, in particular to a method for switching between 2D and 3D software when DirectShow plays stereoscopic video. Background technique [0002] DirectShow is an application system completely based on COM (Component Object Model, that is, Component Object Model). Its component module is a COM component called Filter (filter). Features. The original intention of its design is to free application developers from complex data transmission, hardware differences, audio and video stream synchronization, etc. The overall application framework and underlying work are completed by the various functional filters of DirectShow. What programmers need to do is to design The function of the entire application, determine the Filter to be used, and then correctly connect each functional module and control the processing of the entire data flow through the management model of Filter Graph. [0003]...
