Subjective visual angle posture capturing and real-time image system integral connection introduction: firstly, the signal marking tree is installed at the top end of the visual effect controller, and the visual effect controller is installed at the head of the keel frame by using a buckle and a bolt clamp to fix the visual effect controller after the signal marking tree and the visual effect controller are connected by using a transmission line. Then install two controllers on keel frame left and right sides handle, use the buckle bolt to fix it, install the transmitter end and the receiver end of picture transmitter respectively on work and keel frame maincenter region simultaneously. The map 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 the HDMI female port of the workstation. And then the map transmitter receiver is installed and fixed on the central position of the keel frame by using a strange hand and a clamp.
Subjective visual angle posture capturing and real-time image system integral working principle introduction: the signal mark tree receives the optical dynamic capture data through the terminal collector, and simultaneously codes and calculates the dynamic capture data collected by the signal mark tree to form computer binary language data which is transmitted to a workstation and is attached to a virtual camera in three-dimensional manufacturing software motionon build. The work station 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 mainly controls a virtual camera established in three-dimensional manufacturing software motionbuilt on a workstation and performs related operations such as azimuth control, pushing, pulling, shaking, moving and the like on the virtual camera.
The signal tag tree is used for receiving a dynamic capture data signal, and comprises: the device comprises a receiving terminal ball, a signal transmission framework and a signal processor.
The receiving terminal ball is a spheroid which is made of special pc material and has the diameter of 1.2cm, the receiving terminal ball is used for receiving infrared light signals emitted by the dynamic capture system, and the dynamic capture system emits out invisible infrared light signals of 850nm through a specific capture machine. The infrared light signals are irradiated on the receiving terminal ball of the signal marking tree, the receiving terminal ball reflects the infrared light signals to the moving capture system, so that infrared light signal interaction is carried out between the receiving terminal ball and the capture machine, and the moving capture system obtains position information of the receiving terminal ball according to the infrared light signals reflected by the receiving terminal ball. The receiving terminal ball is made into a spherical shape so as to enlarge infrared signals which are received by the terminal ball and sent out and fed back by the dynamic catching machine, and even if part of the spherical surface of the receiving terminal ball is shielded, the infrared signals sent out by the dynamic catching system cannot be completely received.
The signal transmission framework is made of titanium alloy, the titanium alloy is strong in hardness and not easy to damage, and meanwhile, a high-efficiency signal transmission medium is formed through special manufacturing and processing of the optical fiber, the insulating layer, the flame-retardant layer, the titanium alloy mesh layer and the like from inside to outside. In order to match the receiving terminal ball more efficiently, the signal transmission frameworks of the invention all adopt titanium alloy frameworks with different lengths, the diameters of which are 3mm and the lengths of which are 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 correspond to the receiving terminal balls one to one. The signal transmission framework transmits the infrared light signals 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 outer box. The signal processor is used for processing the infrared light signals, intelligently analyzing, calculating and compiling the infrared light signals received by the receiving terminal balls in all directions through the IC bidirectional chip, and regenerating data signals which can be identified and used by the three-dimensional manufacturing engine in the workstation.
The signal mark tree is composed by the following steps: the bottom of the receiving terminal ball is welded by using soldering tin, the soldering tin has a conduction function, and then the spring buckle at the bottom of the receiving terminal ball is buckled with one section of the signal transmission framework. Then, one ends of the signal transmission frameworks connected with the receiving terminal balls are connected to reserved hole positions on the signal processor one by one and are firmly welded and fixed by soldering tin. And the other ends of the signal transmission frameworks connected with the receiving terminal balls are arranged at the signal receiving hole positions above the visual effect controller 4 and are firmly welded and fixed by soldering tin.
The position of a user handheld device (a subjective visual angle posture capturing and real-time image system) is determined through a receiving terminal sub-ball, motion state information of the device is determined, such as X-axis movement, Y-axis movement, Z-axis movement and the like, the position and the motion state information of the user handheld device are transmitted to a signal processor together, and the signal processor is sent to a workstation in a unified mode and is bound with a virtual camera.
The controller is used for controlling the virtual camera in the three-dimensional production engine in the workstation and carrying out a series of direction position operations and virtual camera shooting on the virtual camera. The controller includes: a controller receiver and a controller transmitter.
The controller and the signal label tree are two independent modules and are respectively responsible for respective work, wherein the controller refers to: controlling the position of the camera in the three-dimensional software on the workstation, such as controlling the camera to move (up, down, left, right and swing), and simultaneously 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 performs the command operation on the virtual camera. The moving part is a virtual camera and transmits pictures obtained by real-time movement to the visual effect controller and the cloud through the signal processing module and the image transmission module. The controller controls the camera, and controls a virtual camera created in the three-dimensional engine, and is not equipment held by a user.
The controller receiver is used for transmitting the operation instruction signal received by the receiver terminal to the three-dimensional production virtual engine in the workstation and carrying out transmitting end instruction operation on the virtual camera.
The controller transmitter is used for sending operation command signals of pushing, pulling, shaking, moving and shooting to a receiver terminal of the controller receiver through a transmitter terminal of the controller transmitter.
When the user presses the push button, the virtual camera lens picture in the three-dimensional production engine of the workstation is pushed forward relatively. When the pull button is pressed, the virtual camera lens in the engine is pulled far. The push button and the remote button have two working modes, one is click type, and the other is long-press type: the long-time pressing mode means that a user presses the push button all the time, and the virtual camera can push the picture all the time until the focal length of the virtual camera is maximum; and the pull key is pressed all the time, and the virtual camera can zoom out the picture all the time until the focal length of the virtual camera is minimum.
