Embodiment Construction

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

[0026] The purpose of the present invention is to provide a three-dimensional scene acquisition device based on a plurality of plane mirrors 2, including a camera 1 and N plane mirrors 2; N is at least 4. The N plane mirrors 2 respectively image the three-dimensional object 4 to be photographed, and the formed virtual image is located in the field of view of the camera 1; the camera 1 photographs the virtual image, and the N images obtained are used to obtain a three-dimensional scene. To facilitate installation, the device of the present invention further 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 3D scene acquisition device, the device has fast scene acquisition speed and is not affected by the uneven illumination of th...

Abstract

The invention discloses a three-dimensional scene obtaining device based multiple plane mirrors, and the device employs a camera and a plurality of plane mirrors for obtaining a three-dimensional scene. Compared with an active three-dimensional scene obtaining device, the device is high in scene obtaining speed, and is not affected by the illumination nonuniformity of an environment. Compared with a light field obtaining system, the device employs the plurality of plane mirrors in a spatial coding process, and the plane mirrors do not introduce new optical aberration and do not reduce the light transmission, thereby causing no impact on an imaging effect. Meanwhile, the device provided by the invention is convenient to carry and machine, and a light field obtaining region is not limited by the size of an entrance pupil of a camera, thereby facilitating the adjustment of the light field obtaining region according to the specific needs. According to the device, the device can be used for man-machine interaction, the reconstruction of the three-dimensional scene, and the target recognition and tracking.

Description

technical field [0001] The present 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 the 3D scene. 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 structurally coded light to a 3D object and capturing an image deformed by its surface modulation, and ...
