Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the treatment scheme schematic diagram of first embodiment of the invention;
Fig. 2 is the structural representation of second embodiment of the invention.
Embodiment
In order to make those skilled in the art person understand better the present invention program, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
The invention provides a kind of three-dimensional display method based on real scene, comprise the client of server and several connection servers.The invention provides 2 kinds of embodiment and implement method of the present invention: mobile terminal and Wearable equipment.
In the first embodiment, while adopting mobile terminal, its treatment scheme as shown in Figure 1:
1) take the digital picture at the whole visual angles centered by finding a view a little;
Its concrete step is:
1.1) select scene, formulate roaming route;
1.2) fixed tripod, regulates tripod level;
1.3) set up The Cloud Terrace, regulate The Cloud Terrace level;
1.4) camera is installed, is adopted fish-eye camera, fish eye lens contributes to increase takes visual angle, in image is synthetic, obtains more overlapping region, improves fusion mass;
1.5) determine the first visual angle, take first photo; Clockwise rotate, every 90 degree are taken a photo, last flip vertical 90 degree, photo directly over shooting;
1.6) along roaming route, take the digital photos of next scene, repeat above-mentioned action;
1.7) by scene order and shooting order, photo is input to server and carries out Digital image synthesis operation; Above-mentioned steps is simple, easy to operate, is adapted to common user.
2) Digital image synthesis, server carries out fusion treatment by whole digital pictures of finding a view a little, builds to take the spherical panorama photo of finding a view a little as the centre of sphere; This technology is ripe at present, as disclosed method in patent 2009102425467; In this process, can carry out certain compression to digital picture, to reduce the volume of image; The present invention adopts and in order whole described digital pictures to be projected on sphere, and the edge between described digital picture is carried out to characteristic matching and image co-registration, and final acquisition be take the method acquisition spherical panorama photo of finding a view a little as the spherical panorama photo of the centre of sphere.
3) spherical panorama photo is compressed, and adopt HTML5 fabrication techniques webpage, on webpage, show the distant view photograph of specified view angle;
4) output webpage is to client;
5) customer end adopted WEBGL technology is played up the distant view photograph showing on webpage, to improve the display quality of distant view photograph, makes up the image impairment causing because of compression of images;
6) by the variation at sensor identify customer end visual angle, adjust the visual angle of the distant view photograph showing, to obtain impression on the spot in person, this sensor can adopt and be widely used in the gyroscope of mobile phone, panel computer or other can realize the sensor of this function arbitrarily; It can also increase acceleration transducer etc. further, obtains direction and distance that client moves, thereby along roaming route, represents gradually the distant view photograph that difference is found a view a little, the impression of moving in real scene to obtain people.
By above step, can realize cross-platform exhibiting panoramagram, anyone can utilize digital camera (especially slr camera) to take the comprehensive photo of anywhere as requested, uploads onto the server; Server merges picture automatically, the panoramic pictures of synthesizing spherical, and be made into webpage; Client is to this webpage, because browser is standard configuration, so do not need that any other support software is installed or parts can be opened this webpage, browses the panoramic pictures obtaining.Panoramic pictures is before transferring to client, first through overcompression, to reduce the data volume of transmission; Client, when showing, is utilized the technology such as WEBGL, picture is played up, significantly to improve the quality of picture.The present invention has adapted to mobile Internet age well, and the demand of " sharing " whenever and wherever possible, has market outlook.
As shown in Figure 2, the client of the second embodiment is Wearable display device, it comprises a shell 10, shell 10 is interior arranges two displays 12 that correspond respectively to two eyes of wearer, the gyroscope (not shown) that one monitoring shell 10 angles change is also set in shell 10, server (not shown) connects display to carry video and the picture signal of high definition by video line 14, and by USB connecting line 16 connection servers, the angle with conveying shell 10 changes gyroscope.
Its treatment step is slightly different from the first embodiment, at server, panoramic pictures is played up, and so just can simplify the requirement to Wearable display device, and any one has the Wearable equipment of Presentation Function all can realize this method.
In addition, server calculates the real visual angle deviation of left and right eyes according to people's interpupillary distance, make the webpage of the distant view photograph at eyes visual angle, two corresponding left and right of difference, and two webpages are flowed to respectively to a display.Like this, can avoid the different distortions that cause in visual angle because of two eyes.
On shell 10, be also provided with the knob 18 that regulates interpupillary distance, spacing and the angle of 18 two displays of knob regulate.Thereby, make different people wear this Wearable display device and can obtain the very high sense of reality.
The above is only the specific embodiment of the present invention.Protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses, and the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
