Brief introduction of 3D stereo photography technology

At present, most of the three-dimensional film production still stays in the virtual drawing state of computer 3D. Real shooting requires several people to work at the same time because of synchronous focusing, synchronous zooming and synchronous angle adjustment of two cameras, which is very difficult to coordinate, which brings a lot of trouble to the previous 3D shooting. This problem has been effectively solved. If there are minor errors in 3D data, they can be corrected in later editing. Based on my long-term experience in stereo photography, two relatively movable cameras are installed on two metal slide rails, and each camera can be adjusted manually and automatically, such as rotation, pitch and roll. The head uses electronic ranging to drive the focal length of the camera and the angle between the two cameras, and at the same time adjusts the angle between the two machines to an absolutely equal position corresponding to the scale on the head, which is an isosceles triangle. In this way, the screen effect can be adjusted at any time through the stereoscopic display. You can even use multiple cameras to automatically track dynamic people or objects to adjust the distance and included angle of multiple cameras. At present, there is no similar product with synchronous adjustment of pan/tilt in China. Please refer to my design drawing for the product structure, which is the introduction of the three-dimensional film shot by dv. After the motor drive signal is given by electronic ranging, the two pan/tilt will move, rotate and pitch in opposite or opposite directions. The driving motor is a DC servo motor or a stepping motor, and the signal source can be a manual pulse signal generator or a wireless focusing driving motor. The rotating structure adopts turbine scroll bar structure and the linear slider adopts lead screw structure.
