Description

Technical Field

[0001] The present invention relates to the technical field of data collection and processing, and in particular to an image data processing method and system. Background Art

[0002] The scenes seen by the left and right eyes are different, which is the main reason why people can perceive three-dimensional space. In modern terms, it is binocular parallax, which is also the basic principle of stereoscopic images. Stereoscopic imaging can be divided into two categories: static scene shooting and dynamic scene shooting. To shoot static scenes, you only need to use a camera to take a photo at a certain position and angle, and then move the camera parallel to a distance and take another photo, so that you can get a set of stereoscopic photos with parallax. To shoot dynamic scenes, you need to use a special stereo camera (such as a dual-lens camera), or two cameras to take two photos at the same time, that is, to get a set of stereoscopic photos with parallax. However, the lenses of current stereo cameras are on the same side. Due to the occlusion effect of the object being photographed, the stereo camera cannot record all the image information of the object being photographed, and it is difficult to generate complete three-dimensional image information in the future.

[0003] The document with application number 20110329 proposes that a stereo camera that obtains a set of images through a single shot shoots the object multiple times from different angles and synthesizes the set of images into a three-dimensional model. However, in the actual shooting process, the different angles and positions during the multiple shots are necessary data for the three-dimensional model construction process. Therefore, recording the angle and position of each image in a set of images relative to the reference system has become a tedious but indispensable part of the modeling process. The tedious data recording process also restricts the promotion of this three-dimensional modeling technology. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an image data processing method and system with a fixed reference system and convenient for calculating the shooting angle and position.

During the period, that is, to determine the order position of a single frame of image in all image data, the shooting angle and position of this frame of photo relative to the photographed object can be known, reducing the image loss caused by the occlusion of the photographed object, simplifying the shooting process, and facilitating subsequent image processing.
