On December 2nd, the 7th Beijing International Advanced Image Exhibition (ICEVE) continued. At this conference, experts and scholars from home and abroad introduced foreign advanced virtual reality imaging technology. In addition, some domestic and overseas panoramic camera brands also appeared at the exhibition, and today I will take you for an inventory.
First, OmniCam
OmniCam, a panoramic camera produced by the Fraunhofer Institute in Germany, according to the staff, the principle of this device is to use mirror refraction to make the lens distortion into a regular rectangle. The image output of each lens is easier to assemble, and it is convenient to support the expansion of the camera. Today, a panoramic camera consisting of 10 industrial cameras is displayed. The horizontal angle of view of each camera is 36 degrees, and 360-degree panoramic shooting can be achieved by intra-machine stitching.
The picture shown above shows the machine placed on the spot and the real-time output. The biggest advantage of this camera is that the real-time stitching process is better and the safety distance is also close. Several visitors tried to put their hands closest to the fuselage, and the adjacent screen did not show obvious seams.
According to the official introduction, the resolution of this camera can reach 10000*2000 pixels. With the support of Fraunhofer development stitching algorithm, it can be spliced ​​in real time, with a safe distance of less than 1 meter and a vertical field of view of 60 degrees. In addition, this camera also supports 3D shooting, by adding 10 cameras next to the original 10 cameras to form 10 groups, you can shoot 3D effects.
Second, strong oxygen technology
The Oxygen Technology brought three sets of cameras this time, from the right to the left, the 3D camera, the nine-eye panoramic camera and the three-eye panoramic camera.
The strong oxygen technology has always been an important partner of LeTV Sports VR live broadcast. The on-site staff introduced more than half of the sports VR live content of LeTV Sports. The live broadcast is usually used with a trinocular camera and a nine-eye camera (mostly three eyes), while the left 3D camera is their new product, which will be officially released in the near future.
Third, IDEALOEYE
IDEALOEYE, a panoramic camera brand of Chengdu IDEALSEE GROUP, has brought 21-purpose professional-level panoramic camera IDEALOEYE P21. This camera can currently support 4K*2K, 30FPS live broadcast and 8K*4K, 60FPS recording. According to the staff of IDEALOEYE, the splicing process is completed in the machine and can be transferred to the all-in-one machine of the brother brand IDEALENS through WI-FI.
Qingting.com has tried this product on the spot. The performance and the stitching effect of the picture are very good. However, there will be a delay of about 3s and a problem of stuck from time to time. The staff said that this is mainly due to the optimization of the App and the poor quality of the live WIFI. They had previously tried live broadcasts with this device at Tan Weiwei's concert (because the VR live broadcast rights were won by Seven-dimensional technology, IDEALOEYE did not play at the end), even in the relatively dark environment of the concert, the playback effect was not bad.
IDEALOEYE will begin mass production in the near future. Although there is no final pricing, the staff revealed that the current price is about 300,000. Previously, a content team had rented the equipment and the daily rent was as high as 20,000 yuan. In addition, IDEALOEYE also brought two other products targeting different user groups, namely consumer-grade device IDEALOEYE C2 and professional-grade device IDEALOEYE C4.
Fourth, Upano & SightPano
Interactive SightPano and Polaro Technology Upano also participated. The interactive vision itself does not do hardware solutions, but provides an integrated shooting solution. Although Upano is mainly based on content production, but he has made a panoramic camera X1, and now the series of VR TV series "Urban Freak" is being produced by this camera.
Five, DK VISION
DK VISION also brought their panoramic camera, DK AURA. However, the more you look at it, the more familiar you are.
Ok……
Sixth, the times
In addition to the VR camera, this exhibition also features the Beijing Times Turing Company, which focuses on panoramic sound recording. Time Turing just held a press conference in Beijing and released a complete set of panoramic sound solutions. This time, Turing brings a professional-grade recorder based on sound field technology.
At the scene, Time Turing also placed a set of equipment to show the recording effect. Wearing a Vive helmet will enter a virtual space with four light balls representing the playing of different popular music. Rotate left and right in the scene to feel the sound of the four singers coming from different directions.
It is reported that this recording device generates a wav file that records the location information of the support. It can be applied to VR games and VR videos through the playback plug-in developed by Time Turing.
