New Description: [New Technology Field] This creation is about the structure design of a background gantry used for photography, especially a background that makes the three-dimensional ring photography have a beautiful and flat image when shooting at different angles of view. Instead of shooting a background stand with a messy background. This can save the post-production of the ring photography to remove the background work, even if you still want to completely remove the background, it will get a good background picture because of the use of this creation, which makes the background removal work much easier, and greatly reduces the difficulty of the ring photography work. And the production time cost, and the original image quality is less likely to produce possible image quality loss. [Prior Art] The characteristics of three-dimensional toroidal photography are to shoot images of many different angles of view for the same object (see section -®). After the software is combined into an interactive three-dimensional object film (oily movie) It allows viewers to flip through the different views of the objects through the human-machine interaction device such as the electric image and the mouse. Because it is analog stereo, and can be viewed by the viewers themselves, the three-dimensional object photography is very different from the one-view-only plane photography. General object (commodity) flat photography One lens is arranged only for one or a few angles of view. 'The background is easier to set up' so that the captured image can avoid the environment and the poorly arranged place. However, three-dimensional toroidal photography is to shoot a large number of images of different perspectives in sequence for the same object. At the same time, it is difficult to avoid ingesting the environment background of different perspectives of the objects. These environmental background images sometimes photograph the machine and the floor. Wires, sometimes photographed with obvious optical and optical differences between the turntable and the background cloth; flat, the picture is not beautiful. The method of visual processing is to manually perform digital image post-production to remove background and image synthesis. This kind of post-production work that removes the background of different viewing angles of the same M353390 object is quite difficult and heavy, and its workload is often many times larger than the shooting operation, which makes the cost of ring photography production high and the process of back-synthesis in a large number of images. In the case of digital or procedural errors, the possibility of image realism is impaired. There is a certain degree of quality risk in the digital collection work that attaches great importance to image quality and authenticity. This creation can greatly reduce the difficulty of three-dimensional ring photography background layout processing, shorten the overall production time and cost' and improve image quality and true reliability. ^ [New Content] In the process of three-dimensional ring photography, the two main processes of shooting and post-production to remove the background are generally required. The ring photography takes dozens to hundreds of photos to make high-quality Removing the background is a very difficult and arduous task. 'This creation provides a background gantry design that is specifically designed to work with three-dimensional toroidal photographic frames. This allows for a simple and beautiful background when shooting, which can greatly reduce the difficulty and burden. The removal of background post-production work reduces the cost of production. The gantry design body is a background platform that can adjust the height of the support foot (2) (d, the front end of the background platform (1) is slightly narrower and the rear end is slightly wider than the T-shape, so that the ring photographic frame (D) arm struts It can operate normally, because the photography principle is that the foreground is smaller, the rear view is larger, and at the same time it can maintain a larger background area. The background platform (1) has a three-dimensional ring photography frame ( D) The cargo turntable (E) is a hole with a diameter of 1 cm and precisely cut. The support foot (2) of the background platform (1) can be adjusted according to the height of the load carousel (E). Mainly according to the background platform (1) size plus the facade Background highly tailored - sheet background cloth (or photographic background paper) (3), background cloth (3) in the background platform (1) round hole position is also precisely cut - round hole 'but the circle radius must be smaller than the platform The radius of the round hole is about 15 cm' to make the gap between the carrier turntable (E) and the background platform (1) well shielded. The background fabric (3) has a round hole-end alignment with the background platform (1) round end and the other side extends Hanging on the background frame, and paying attention to the circular fox shape when the façade turns to the plane, it can form a The flat background of the cargo turntable (8), and the need to replace the pure color back M353390. The main features of this creation are: 1. Matching the ring photography frame (D) the carousel (E) Background platform (1) round hole and flat background cloth pad (3) structure design, dirty and smooth, can cover the inevitable messy environment background in the shooting range, so that any shooting angle of the ring photography is beautiful 2. The background platform (1) T-shaped design can match the ring photography frame 〇>) the arm struts operate normally, while maintaining a large background shielding area. 3. The support platform (2) of the background platform (1) can be used with the ring photography camera (D) to turn the height of the carousel (the sleek and fine-tuning height, so that the background platform (1) can adapt to the work surface or the desktop that is not completely flat. In case of hindering the rotation of the cargo turntable (E), it should be as close as possible to the edge of the loader (£) to form a simple and beautiful shooting background. 4. The background platform (1) and the support foot (2) can be easily disassembled. Assembly, easy to belt and collect. [Embodiment] Please refer to the third, fourth, fifth and sixth figures. This creation provides a background structure design for three-dimensional ring photography. One of the photography work equipment. The following is a brief description of the implementation of this creation in the process of three-dimensional ring photography: L erected three-dimensional ring photography (D) and digital camera (C). 2 erect background platform (1) ' Screw the support foot (2) screw into the background platform (1). The boring is assembled so that the carrier turntable (E) is located at the center of the background platform (1), and the background platform (1) is wide and backward. The front is facing. 3. Adjust the background platform (1) support the foot (2) 'to make the background flat The height of the table (1) is lower than the lower edge of the edge of the M353390 disk. 1~2 cm. 4. Lay the background cloth (3) so that the cloth surface is flat, the edge is aligned with the background platform (1), and the center of the circle is aligned with the center of the platform hole. Background cloth pad (3) Around the round hole than the background platform (1) The outer edge of the round hole is located under the turntable (Ε), and after completion, the number of clips is clamped at the aligned edge of the background platform (1) and the back view cloth cushion (3). 5. Fix the background frame (8) and place the background fabric (3) rear façade on the façade background frame (Β). 6. Adjust the background platform (1) Support the chat seat (2), raise the height of the table to approximately cut At the lower edge of the edge of the pinch turntable (Ε), the principle is as close as possible but does not hinder the smooth rotation of the plant turntable (ε). 7. Adjust the background cloth pad (3) to make the façade and the plane junction neatly arc Shape, the entire background must be smooth and tidy. 8·Set up photography lighting 'Preliminary inspection of the background after lighting effect, if necessary, should continue to adjust the background cloth or lighting, so that the overall fit to achieve the desired effect. 9. Set the object to be photographed, and Fine-tune the object, camera, and then the object The photography workflow is completed.
