Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0026] The purpose of the present invention is to provide a three-dimensional scene acquisition device based on multiple plane mirrors 2, including a camera 1 and N plane mirrors 2; N is at least 4. The N plane mirrors 2 form images of the three-dimensional objects 4 to be photographed respectively, and the formed virtual images are located in the field of view of the camera 1; the camera 1 shoots the virtual images, and the obtained N images are used to obtain a three-dimensional scene. For the convenience of installation, the device of the present invention also includes a support structure 3 for fixing the N plane mirrors 2 , and the plane mirrors 2 are compactly spliced ​​on the support structure 3 .

[0027] Compared with the active three-dimensional scene acquisition device, the device has fast scene acquisition speed and is not affected by the uneve...

Abstract

The invention discloses a three-dimensional scene acquisition device based on a plurality of plane mirrors, which can obtain a three-dimensional scene by using one camera and a plurality of plane mirrors. Compared with the active three-dimensional scene acquisition device, the scene acquisition speed is fast, and it is not affected by the uneven illumination of the environment; compared with the light field acquisition system, since multiple plane mirrors are used in the spatial encoding process, the plane mirror does not Introducing new optical aberrations without reducing the light transmittance, so as not to affect the imaging effect; at the same time, the device provided by the invention is easy to carry and process, and the area of ​​the light field acquired is not limited by the size of the entrance pupil of the camera, which is convenient according to specific needs. Adjusts the area that the light field acquires. The device for acquiring a 3D scene according to the present invention can be applied to human-computer interaction, 3D scene reconstruction, target recognition and tracking.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, in particular to a portable three-dimensional scene acquisition device based on a plurality of plane mirrors. Background technique [0002] The 3D scene acquisition device used for human-computer interaction, 3D scene reconstruction, target recognition and tracking has become a popular product in recent years because it provides depth information of 3D scenes. The 3D scene display device can be applied to entertainment applications such as somatosensory games and movie special effects production, as well as high-end applications such as scientific research, medical / business training, flight training, and immersive entertainment. [0003] The 3D scene information acquisition method can be realized by using active 3D measurement. This method utilizes projecting structured coded light to a 3D object and taking images deformed by its surface modulation, and calculates the sha...
