Embodiment 1

[0097] Embodiment 1: The scale factor restoration result of the ground data of a certain studio, by calculating the scale factors corresponding to the four side lengths, taking the average value as the scale factor of the entire scene. Because the coordinates output by the triangulation algorithm have no units, we define "m" (unit meter) in the scale factor. The experimental results are as follows:

[0098] side length 1 side length 2 side length 3 side length 4 average value Actual length 2.8m 2.8m 5.6m 5.6m reconstruction length 523.0 543.3 986 1124.2 scale factor 0.00535m 0.00515m 0.00567m 0.00498m 0.00528m

[0099] The reconstruction result of the present invention to a segment of video data is as follows: Figure 4 shown; among them, Figure 4 (a) is the input video sequence, Figure 4 (b) for the matching process, Figure 4 (c), (d) are reconstruction results from different angles.

Abstract

The invention provides a scale reduction method and system, a three-dimensional reconstruction method and system, a storage medium and equipment, and aims at solving the technical problem that compared with traditional monocular three-dimensional reconstruction, the development cost and the data processing complexity of the prior art are increased. The method comprises the steps: obtaining an i-thkey frame; obtaining a j-th key frame at the position with the translation vector Ti, j away from the i-th key frame; wherein each angular point coordinate of the i-th key frame is correspondingly matched with each angular point coordinate of the j-th key frame; according to the i-th key frame angular point coordinate and the j-th key frame angular point coordinate, obtaining a geometrical relationship between the i-th key frame and the j-th key frame, and obtaining a scale factor lambda for three-dimensional reconstruction.

Description

technical field [0001] The present application relates to the field of image processing, in particular, to a scale reduction and three-dimensional reconstruction method, system, storage medium and equipment. Background technique [0002] With the development of video technology, the application of AR (augmented reality), VR (virtual reality) and MR (mixed reality) is becoming more and more perfect. 3D reconstruction is a key technology in their interdisciplinary field. So far, there are mainly the following types of solutions: [0003] 1) In terms of equipment, the data that 3D reconstruction technology relies on can be obtained from monocular cameras, binocular cameras, and depth cameras. Of course, considering the cost of equipment, their costs increase sequentially, but analyzing the difficulty of data processing, it is the opposite relationship. [0004] 2) Related to the requirements of actual AR, VR or MR applications, some functions require online processing of vide...
