Subjective visual angle posture capturing and real-time image system integral connection introduction: firstly, a signal marking tree is installed at the top end of a visual effect controller, and a data transmission line is used for connecting the signal marking tree and the visual effect controller, and then the visual effect controller is installed at the head position of a keel frame and is fixed by using a buckle and a bolt clamp. And then the two controllers are arranged on the left and right grips of the keel frame, the two controllers are fixed by using the buckle bolts, and simultaneously the transmitter end and the receiver end of the image sensor are respectively arranged on the work and the central region of the keel frame. The image sensor transmitter is connected with the workstation by using an HDMI (High Definition Multimedia Interface ) transmission line, one end of the transmission line is connected with the transmitter, and the other end of the transmission line is inserted into a HDMI female port of the workstation. The image sensor receiver is then mounted and secured to the keel in a centered position using monster hands and clips.
The whole working principle of the subjective visual angle posture capturing and real-time image system is introduced: the signal mark tree receives optical dynamic capturing data through the terminal collector, and meanwhile codes and solves the captured dynamic capturing data to form computer binary language data, and the computer binary language data is transmitted to a workstation and is added to a virtual camera in the three-dimensional manufacturing software MotionBuild. The workstation picture is transmitted to the picture transmitter receiver end by the picture transmitter base station transmitting end through the stream code compression technology, and the picture is resolved into video data by the video stream soft decoding H264 and transmitted to the visual effect controller through the HDMI transmission line. The controller is mainly used for controlling a virtual camera built in the three-dimensional manufacturing software MotionBuild on the workstation and performing related operations such as azimuth control, pushing, pulling, shaking, moving and the like.
The signal mark tree is used for receiving dynamic capture data signals, and comprises the following components: the device comprises a receiving terminal ball, a signal transmission framework and a signal processor.
The receiving terminal ball is a sphere with the diameter of 1.2cm made of a special pc material, and the receiving terminal ball is used for receiving an infrared light signal emitted by the dynamic capture system, and the dynamic capture system emits an invisible infrared light signal of 850nm outwards through a specific capture machine. The infrared light signals are irradiated on the receiving terminal balls of the signal mark tree, the receiving terminal balls reflect the infrared light signals to the dynamic capturing system, so that infrared light signal interaction is carried out between the receiving terminal balls and the capturing machine, and the dynamic capturing system obtains the position information of the receiving terminal balls according to the infrared light signals reflected by the receiving terminal balls. The spherical receiving terminal ball is made to enlarge the infrared light signal sent and fed back by the dynamic capturing machine, and even if part of the spherical receiving terminal ball is covered, the infrared light signal sent by the dynamic capturing system cannot be received completely.
The signal transmission skeleton is made of titanium alloy, the hardness of the titanium alloy is very strong and the titanium alloy is not easy to damage, and meanwhile, the high-efficiency signal transmission medium is formed through special manufacturing and processing of optical fibers, insulating layers, flame-retardant layers, titanium alloy net layers and the like from inside to outside. In order to better and efficiently match the receiving terminal ball, the signal transmission frameworks all adopt titanium alloy frameworks with different lengths, wherein the diameter of the titanium alloy frameworks is 3mm, and the length of the titanium alloy frameworks is 10cm-25 cm. The number of the signal transmission frameworks is the same as that of the receiving terminal balls, and the signal transmission frameworks are in one-to-one correspondence with the receiving terminal balls. The signal transmission skeleton transmits the infrared light signal received by the receiving terminal ball to the signal processor.
The signal processor comprises an IC bidirectional intelligent chip, a rheostat, a miniature circuit board and a rigid body outer box. The signal processor is used for processing the infrared light signals, the infrared light signals received by the receiving terminal ball in all directions are intelligently analyzed, calculated and compiled through the IC bidirectional chip, and data signals which can be identified and used by the three-dimensional manufacturing engine in the workstation are regenerated.
The signal mark tree comprises the following components: the bottom of the receiving terminal ball is welded by using soldering tin, the soldering tin has a conducting function, and then the spring buckle at the bottom of the receiving terminal ball and one section of the signal transmission framework are buckled with each other. And then, one ends of all signal transmission frameworks connected with the receiving terminal balls are connected to reserved hole sites on the signal processor one by one and are firmly fixed by soldering tin. The other ends of all the signal transmission frameworks connected with the receiving terminal balls are arranged on the signal receiving hole positions above the visual effect controller 4 and are firmly fixed by soldering tin.
The position of the handheld device (the subjective visual angle gesture capturing and real-time imaging system) of the user is determined by receiving the terminal ball, movement state information of the device such as X-axis movement, Y-axis movement, Z-axis movement and the like is determined, the position of the handheld device of the user and the movement state information are transmitted to the signal processor together, and the position and the movement state information are uniformly transmitted to the workstation by the signal processor to be bound with the virtual camera.
The controller is used for controlling the virtual camera in the three-dimensional making engine in the workstation and performing a series of directional position operations on the virtual camera and image capturing of the virtual camera. The controller includes: a controller receiver and a controller transmitter.
The controller and the signal marking tree are two independent modules, and are respectively responsible for respective work, wherein the controller refers to: controlling the camera in the three-dimensional software on the workstation, such as controlling the position movement (up, down, left, right, panning) of the camera, and controlling the lens of the camera, such as: aperture, focal length. The controller does not move the device held by the user when the controller instructs the virtual camera. The virtual camera is moved, and the pictures obtained by moving in real time are transmitted to the visual effect controller and the cloud end through the signal processing module and the image transmission module. The controller, when controlling the camera, controls the virtual camera created in the three-dimensional engine, not the device that our user holds.
The controller receiver is used for transmitting the operation command signals received through the receiver terminal to the three-dimensional manufacturing virtual engine in the workstation, and performing transmitting end command operation on the virtual camera.
The controller transmitter is configured to transmit operation instruction signals of push, pull, shake, shift, and image pickup to a receiver terminal of the controller receiver through a transmitter terminal thereof.
When the user presses the push button, the virtual camera lens picture in the three-dimensional production engine of the workstation can be relatively pushed forward.
