Problems solved by technology

[0003] Real-time transmission and reconstruction of 3D images puts forward higher requirements for the system's processing capability. Because the viewer needs to change the viewing content, the system is required to quickly switch between image acquisition, processing, and projection, which brings great challenges to the system. At the same time, the collection place of the target object will limit the image collection effect to a certain extent, and the shape and size of the target object also put forward higher requirements for the collection method and projection method

Embodiment 1

[0066] A 3D image reconstruction system, such as figure 1 Shown, including in turn the data connection's:

[0067] 1. An image acquisition unit, used to acquire the panoramic image data of the target object;

[0068] Such as image 3 As shown, the image acquisition unit includes a guide rail, a camera, and a slider, the camera is mounted on the slider, and the slider moves along the guide rail; the types of the camera include but are not limited to a monocular camera, a binocular camera, and a depth camera .

[0069] Such as Figure 6-7 As shown, the slider includes a loading platform and three pulleys that drive the loading platform to slide;

[0070] The guide rail is a circular guide rail composed of four smoothly connected arcs, such as Figure 5 As shown, each arc includes a first groove on the side close to the target object and a second groove on the side away from the target object, so that the cross section of the arc is approximately in the shape of a "mountain...

Embodiment 2

[0084] A three-dimensional image reconstruction method, such as figure 2 shown, including steps:

[0085] Plan the shooting points according to the size of the target object and the shape of the guide rail to ensure that the 360° panoramic image of the target object can be obtained. The target object in this embodiment is relatively regular, so it is planned to shoot in four directions: front, back, left, and right;

[0086] Collect the panoramic image data of the target object, and use the stereo vision processing technology to calculate and synthesize the three-dimensional model of the object;

[0087] Render the 3D model and generate several perspective views Figure II dimensional image;

[0088] Based on the principle of Pepper's illusion, the two-dimensional image is projected, reflected, and formed into a holographic three-dimensional image.

[0089] When the user command signal is received, the user's gesture signal and voice signal are obtained and analyzed and pro...

Abstract

The invention discloses a three-dimensional image reconstruction system, which comprises: an image acquisition unit used for acquiring panoramic image data of a target object; an image processing unitwhich is used for planning a collection path, controlling the image collection unit to collect the panoramic image data and processing the panoramic image data to obtain an object three-dimensional model; and a holographic projection unit which is used for projecting and reflecting the two-dimensional image to form a holographic image. The image acquisition unit, the image processing unit and theholographic projection unit are sequentially connected. The image acquisition part and the holographic display system part of the three-dimensional image reconstruction system disclosed by the invention can adopt different implementation schemes according to the space size and capital amount of a scene; the three-dimensional image reconstruction system m is high in flexibility, strong in expansibility, diversified in interaction form, good in experience effect, mature and stable in adopted holographic projection scheme, vivid in three-dimensional display effect and capable of being widely applied to various scenes such as exhibition halls, meeting rooms and laboratories.

Description

technical field [0001] The invention belongs to the field of stereoscopic imaging and interactive applications, in particular to a three-dimensional image reconstruction system and method. Background technique [0002] In recent years, with the continuous development of computer rendering technology and display technology, users have continuously improved the stereoscopic display effect and quality of images, and at the same time are eager to interact with images. The traditional remote image reconstruction scheme is to directly transmit the image of the object. Although real-time performance can be guaranteed, due to the original two-dimensional image transmitted, there is no stereoscopic display effect and it cannot be interacted with. In addition, although popular virtual reality devices can interact and have a certain stereoscopic display effect, they cannot be viewed with naked eyes due to the need to wear specific devices in advance, which is troublesome, expensive, an...
