Arrangement and method for the recording and display of images of a scene and/or an object

Abstract

The invention relates to an arrangement and a method for capturing and displaying images of a scene and / or an object. Said arrangement and method are particularly suited to display the captured images in a three-dimensionally perceptible manner. The aim of the invention is to create a new possibility to take images of real scenes and / or objects with as little effort as possible and then autostereoscopically display the same in a three-dimensional fashion from two or more perspectives. Said aim is achieved by providing at least one main camera of a first camera type for recording images, at least one satellite camera of a second camera type for recording images, an image converting device which is mounted behind the cameras, and a 3D image display device, the two camera types differing from each other in at least one parameter. A total of at least three cameras is provided. Also disclosed is a method for transmitting 3D data.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a national phase application of International Application No. PCT / DE2007 / 001965, filed Oct. 29, 2007, which claims priority of German Application No. 10 2006 055 641.0, filed Nov. 22, 2006, the complete disclosures of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]a) Field of the Invention[0003]The invention relates to an arrangement and a method for the recording and display of images of a scene and / or an object, suitable especially for the display of the recorded images for spatial perception. The invention further relates to a method of transmitting images for spatial perception.[0004]b) Description of the Related Art[0005]At present there exist essentially three basically different methods, and the appertaining arrangements, for recording 3D image information:[0006](1) The classical stereo camera, consisting of two like cameras, one each for a left and right image. For a highly resolved display, hi...

AI Technical Summary

Benefits of technology

[0017]Essentially, the advantage of the invention is that, besides the classical stereo camera system, here consisting essentially of two identical high-resolution cameras, a three-camera system is used, preferably consisting of a central high-quality camera and two additional cameras of lower resolution, arranged to the left and right, respectively, of the main camera. Thus, the main camera is arranged between the satellite cameras, for example.

[0018]Preferably then, the main camera is arranged between the satellite cameras. The distances between the cameras and their alignment (either in parallel or pointed at a common focus) are variable within customary limits. The use of further satellite cameras may be of advantage, as this enables a further reduction of misinterpretations especially during the subsequent processing of the image data.

[0019]According to the embodiment of the invention, it may thus be of advantage that

[0020]exactly one main camera and two satellite cameras are provided (“version 1+2”);

[0021]exactly one main camera and three satellite cameras are provided (“version 1+3”); or

[0022]exactly one main camera and five satellite cameras are provided (“version 1+5”).

Problems solved by technology

A disadvantage is the great effort needed to implement exact alignment of the—e.g., eight—cameras with each other.

Another disadvantage is the increased cost involved in the use of several cameras, which in addition entail further problems such as differing white levels, tonal values and / or geometry characteristics, which have to be balanced accordingly.

The high data rate to be handled with this method is also a drawback.

(3) The use of a depth camera. Here, use is made of a color camera jointly with a depth sensor, which registers the—as a rule, cyclopean—depth information of the scene to be recorded. Apart from the fact that depth sensors are relatively expensive, their drawback is that they often do not work very exactly, and / or that no acceptable compromise between accuracy and speed is achieved. The method requires a general extrapolation, in which artefacts, especially in the outer views, cannot be excluded and, generally, occluding artefacts cannot be covered up.
