集成成像3D信息获取技术

集成成像作为一种新型裸眼三维(3D)显示技术,能够完整获取3D信息并还原再现,是目前最具发展前景的裸眼3D显示技术之一。其中,对3D信息的完整获取通过记录场景不同角度的视差信息,并以微图像阵列形式进行呈现,不仅能够为集成成像显示提供3D内容,更作为一种多维度信息获取手段,在被遮挡场景的探测成像、目标识别、2D/3D信息加密和显微3D成像等多个领域得到应用。文中对集成成像3D信息获取的基本原理、不同类型的集成成像3D信息获取技术以及集成成像3D信息实时获取技术进行综述,并讨论现存的一些问题以及未来发展趋势。

3D information acquisition technology of integral imaging

As a novel auto-stereoscopic three-dimensional (3D) display technology, integral imaging is able to acquire complete 3D information of the 3D scene and reconstruct it. Thus, integral imaging is one of the most promising technologies of the glasses-free 3D displays. In the integral imaging 3D information acquisition process, different perspectives of the 3D scene are recorded to generate the elemental image array to be the 3D content for the integral imaging display. On the other hand, the integral imaging 3D acquisition can be a multi-dimensional information pickup approach applied to the detection and imaging of occluded scenes, target recognition, two-dimensional (2D) / 3D information encryption and microscopic 3D imaging fields. The basic principles, different types of the integral imaging 3D information acquisition approaches, and real-time 3D information acquisition technologies were reviewed in this paper. Some challenging problems and future development trend of the technology were also discussed.
