Description
Technical field
The present invention relates to 3D technique for taking field, particularly a kind of single-lens bore hole 3D rendering filming apparatus.
Background technology
Owing to having certain distance between people's the eyes, when the people watched same target by right and left eyes, two angles of seeing were different, and left eye sees that the left surface of object is more, and right eye sees that the right flank of object is more.Thereby form incomplete same image at retina, when the image that this two width of cloth is had a parallax when brain merges mutually, just can produce stereoscopic sensation.Stereoscopic photograph is exactly to utilize this principle to preserve and represent a kind of method for imaging of scenery three-dimensional spatial information, namely take from different perspectives same object, when people's right and left eyes is seen respectively the photographic images of the different angles that have certain parallax, will form the stereo-picture with depth perception.Style of shooting has a variety ofly in stereoscopic photograph, and common mode comprises run-in index and convergence type, adopts only style of shooting under different photographed scenes, can give play to greatest extent its separately exclusive advantage.
Mainly there is two large problems in present stereoscopic photograph technology.First problem is the present Shortcomings of stereoscopic shooting device own.Current stereoscopic shooting device mainly is divided into two large classes, is respectively many lens shootings device and one-shot device.
Many lens shootings device refers to utilize two or many image acquisition units to simulate people's eyes, takes from different perspectives same scenery, thereby obtains the filming apparatus of anaglyph.Yet, when adopting this filming apparatus, be difficult to guarantee that the photocentre of many image acquisition units is in the same level line fully, and the optical axis of each image acquisition units is fully parallel or meet at a bit simultaneously, thereby has a strong impact on the quality of stereoscopic shooting image.Especially when shooting is closely neglected poor scenery, intrinsic image acquisition units size causes image acquisition units camera lens spacing can not be transferred to less numerical value and can't take the stereo-picture that obtains suitable parallax, thereby has limited the coverage of stereo-picture collecting unit and the performance of stereoeffect.And the cost of many lens shootings device is higher, is unfavorable for popularizing.
The one-shot device refers to only adopt an image acquisition units, takes from different perspectives same object by a mobile segment distance, thereby obtains the filming apparatus of anaglyph.Installation was complicated when it had well overcome many lens shootings, debugging difficulty is large, the image acquisition units spacing limits and the high in cost of production problems.Yet present one-shot device can only adopt single style of shooting, can only the parallel image acquisition units take or aim at all the time the reference object shooting, namely can only adopt run-in index to take or the convergence type shooting, there is not a kind of device can possess simultaneously this two kinds of styles of shooting, can't under corresponding photographed scene, immediately switch to only style of shooting, thereby can't reach best stereoscopic shooting effect.
Second largest problem is the in real time only acquisition parameters of calculative determination of present filming apparatus.For present stereoscopic shooting device, can only obtain disparity map and can't guarantee that its disparity map has best parallax, the most suitable human eye is watched.Acquisition parameters during stereoscopic shooting comprises the width of image acquisition units spacing, angle, focal length and imaging CCD.In the situation that imaging CCD width is definite, image acquisition units spacing, angle and image acquisition units focal length are determining the stereoeffect of photographic images during stereoscopic shooting.Stereoscopic photograph is clapped well with bad, catch up with state that the three calculates, adjusts whether direct relation accurately arranged.Along with the difference of photographed far and near distance, three's optimum value also becomes thereupon.This just requires stereoscopic shooting device can calculate in real time the best acquisition parameters that the change with photographed scene changes.And current stereoscopic shooting device all can't calculate and make filming apparatus automatically to make corresponding adjustment in real time, so that the stereo image quality of current shooting is uneven, seriously strengthen photographic images post-processed difficulty and workload, become the bottleneck that restriction stereoscopic shooting technology further develops.
