Problems solved by technology

[0003] In the process of computer-aided artificial 2D video to 3D video conversion, the operator needs to manually mark the object and use the image segmentation method to segment the complete outline of the object, which requires a lot of manual operations and high labor costs.
The manual cost of converting 2D video to 3D video of the movie "Titanic" is as high as 18 million US dollars

Abstract

An image processing method for converting 2D (2-dimensional) video into 3D (3-dimensional) video comprises the steps of taking images, shot from different angles, of a target object as sample images, calculating color invariable images of the sample images and a to-be-identified image, extracting feature points from the color invariable images, matching the feature points in the color invariable image of the to-be-identified image with the feature points in the color invariable images of the sample images, judging whether the target object exists in the to-be-identified image according to distribution of the feature points matched successfully, if the target object exists in the to-be-identified image, dividing a target object outline based on the feature points matched successfully. The method can identify the target object when the 2D video is converted into the 3D video, precisely divides the object outline, and greatly reduces the workload of manual operation.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to an image processing method for converting 2D video to 3D video. Background technique [0002] Object recognition needs to recognize the target object from the complex environment, so that the computer has a preliminary cognitive ability. If the objects in the image can be recognized, part of the three-dimensional information in the image can be restored. Both image analysis and object tracking require a good performance object recognition algorithm as the basis. In image retrieval, security monitoring, medical imaging, robot vision and other fields, object recognition has important applications. The advancement of object recognition technology can further promote the development of related fields in the direction of intelligence and automation. [0003] In the process of computer-aided artificial 2D video to 3D video conversion, the operator needs to manually mark the ...
