Three-dimensional reconstruction and related interaction and measurement methods and related devices and equipment

Abstract

The invention discloses a three-dimensional reconstruction and related interaction and measurement method, a related device and equipment, and the method comprises the steps of obtaining a plurality of to-be-processed images obtained by scanning a to-be-reconstructed target through a camera device; determining target pixel points and camera pose parameters of each frame of to-be-processed image belonging to the to-be-reconstructed target by using each frame of to-be-processed image and the calibration parameters of the camera device; dividing the image data of each frame of to-be-processed image into a corresponding data set in sequence; determining a pose optimization parameter of the data set by using the image data of the data set and the image data and pose optimization parameters of the data set of which the time sequence is located before the image data of the data set; adjusting a camera pose parameter of the to-be-processed image to which the image data contained in the data set belongs by using the pose optimization parameter of the data set; and performing reconstruction processing on the image data of the to-be-processed image to obtain a three-dimensional model of the to-be-reconstructed target. According to the scheme, the three-dimensional reconstruction effect can be improved, and the calculation load of three-dimensional reconstruction is reduced.

Description

technical field [0001] The present application relates to the technical field of computer vision, in particular to a three-dimensional reconstruction and related interaction, measurement method and related devices and equipment. Background technique [0002] With the development of information technology and the improvement of electronic technology, people are more and more fond of using mobile terminals such as mobile phones and tablet computers integrated with camera devices to perform 3D reconstruction of objects in real scenes, so that the 3D images obtained by 3D reconstruction The model implements augmented reality (Augmented Reality, AR), games and other applications on mobile terminals.

Problems solved by technology

[0003] However, when the camera device scans and shoots objects in the real scene, the images obtained from the camera device have different degrees of noise, and the current mainstream camera pose parameter solution method will inevitably introduce some errors. Errors accumulate with scanning and shooting, which affects the effect of the 3D model. In addition, as the field of view of scanning and shooting expands during the entire 3D reconstruction process, newly captured images are continuously integrated, and the calculation load is gradually increasing.
