Because the display time of the display screen is less than the effective time of the control signal of the active shutter type 3D glasses, the shutter conduction of the 3D glasses is a gradually-increasing process, and therefore, a grid phenomenon can often occur, and poor user experience is caused.
In view of the above, the invention provides a 3D glasses control method, device, system, terminal and medium suitable for an LED display device, which cooperate with an LED display screen to effectively alleviate the grille phenomenon occurring in the existing 3D glasses control, and promote the user experience. In order to make the objects, technical solutions and advantages of the present invention more apparent, further detailed description of the technical solutions in the embodiments of the present invention will be given by the following examples with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Embodiment one:
as shown in fig. 2, a schematic structural diagram of a 3D glasses control system suitable for an LED display device according to an embodiment of the present invention is shown. The 3D glasses control system of the present embodiment includes a transmission box 21, an LED display device 22, a wireless transmission device 23, and a 3D vision device 24.
The transmitting box 21 acquires a video source from an external device, transmits video data to the LED display device 22, phase-shifts a control signal, and transmits the control signal to the wireless transmitting device 23, and the wireless transmitting device 23 forwards the control signal to the 3D vision device 24. The external device may be, for example, a computer device or a server device; the LED display device 22 is, for example, an LED display screen; the wireless transmitting device 23 includes, but is not limited to, a WI-FI module, a ZigBee module, an NB-IoT module, a ZigBee module, a 3G/4G/5G module, a Bluetooth module, and the like; the 3D vision device 24 is, for example, active shutter type 3D glasses, and the present embodiment is not particularly limited.
The sending box 21 calculates a first path delay time t1 of the video data from the sending box 21 to the LED display device 22, and calculates a second path delay time t1 of the control signal from the sending box 21 to the 3D vision device 24. It should be understood that the path delay time is generated when the video data or the control signal is transmitted, and the path delay time may be calculated based on a time difference between a signal arrival time stamp and a signal emission time stamp, or may be estimated according to a transmission speed and a transmission distance, which is not limited in this embodiment.
In this embodiment, in addition to the influence factor of the path delay time, the phase shift time t3 required for the shutter control signal of the 3D vision apparatus 24 is also considered to be suitable for the dynamic scanning of the LED display apparatus 22, so as to avoid the occurrence of the grille phenomenon. Taking the active shutter type 3D glasses as the 3D vision device for example, because the display time of the display screen is smaller than the effective time of the control signal of the active shutter type 3D glasses (i.e. the time corresponding to a complete control signal waveform), the shutter of the glasses is conducted and gradually changed, so that in order to relieve the occurrence of the grille phenomenon, the phase shift time t3 is calculated according to the waveform diagram of the conduction of the active shutter type 3D glasses and the complete dynamic scanning time of the LED display screen (as shown in fig. 3), so that the dynamic scanning time of the LED display screen is changed from being identical with the waveform time of the front part in the conduction waveform of the 3D glasses to being identical with the waveform time of the rear part in the conduction waveform of the 3D glasses, and the serious grille phenomenon caused by the gradual change of the conduction waveform is effectively overcome.
After the first path delay time t1, the second path delay time t1, and the phase shift time t3 are calculated, the phase shift t=t1-t2+t3 to be performed by the control signal sent by the sending box 21 is obtained. That is, the total phase shift to be performed by the control signal considers not only the influence of the path delay time (the time difference between the first path delay time t1 and the second path delay time t 1) but also the phase shift time t3 obtained based on the waveform pattern of the glasses shutter conduction and one complete dynamic scan time of the LED display screen.
The sending box 21 performs phase shift t processing on the control signal and then transmits the control signal to the wireless transmitting device 23, and the wireless transmitting device 23 transmits the control signal to the 3D vision device 24.
It should be noted that, some existing solutions only adjust the control signal by measuring the opening time of the 3D glasses shutter, and some existing solutions send the video data and the control signal from the sending box synchronously, which do not consider the problem of path delay, and these existing solutions have obvious disadvantages and still cause the occurrence of the grid phenomenon. The phase shift t of the sending box provided by the invention for the control signal considers not only the path delay of video data and the control signal, but also the phase shift of the control signal of the 3D glasses shutter for adapting to the dynamic scanning of the LED display screen, thereby avoiding the occurrence of the grating phenomenon and fundamentally relieving the occurrence of the grating phenomenon.
Embodiment two:
fig. 4 is a schematic flow chart of a method for controlling 3D glasses suitable for an LED display device according to an embodiment of the present invention, which mainly includes the following steps.
Step S41, obtaining a video source.
Step S42, the video data is sent to the LED display device.
Step S43, transmitting the control signal after phase shift to the 3D vision equipment; it should be noted that, the sending of the control signal to the 3D vision device according to the present embodiment may refer to directly sending the control signal to the 3D vision device, or may refer to forwarding the control signal to the 3D vision device after passing through other devices (such as a wireless transmitter), which is not limited in this embodiment.
In this embodiment, the phase shift time is associated with the path delay time, the shutter-on waveform of the 3D vision device, and the dynamic scan time of the LED display device, and the calculation process is as follows:
step S431, calculating a first path delay time generated by transmitting video data to the LED display device; let the first path delay time be t1.
Step S432, calculating a second path delay time generated by transmitting the control signal to the 3D vision device; let the second path delay time be t2.
It should be understood that the path delay time is generated when the video data or the control signal is transmitted, and the path delay time may be calculated based on a time difference between a signal arrival time stamp and a signal emission time stamp, or may be estimated according to a transmission speed and a transmission distance, which is not limited in this embodiment.
Step S433, calculating a first phase shift time according to the shutter conduction waveform of the 3D vision device and a complete dynamic scanning time of the LED display device; let the first phase shift time be t3.
Step S444, calculating a second phase shift time for performing a phase shift process on the control signal; the second phase shift time is configured as a sum of a time difference of the first path delay time and a second path delay time and the first phase shift time; let the second phase shift time be t, then the calculation formula of t can be expressed as t=t1-t2+t3.
In this embodiment, in addition to the influence factor of the path delay time, the phase shift time t3 required for the shutter control signal of the 3D vision apparatus is also considered to be suitable for the dynamic scanning of the LED display apparatus, so as to avoid the occurrence of the grille phenomenon. Taking the active shutter type 3D glasses as the 3D vision device for example, because the display time of the display screen is smaller than the effective time of the control signal of the active shutter type 3D glasses (i.e. the time corresponding to a complete control signal waveform), the shutter of the glasses is conducted and gradually changed, so that in order to relieve the occurrence of the grille phenomenon, the phase shift time t3 (as shown in fig. 3) is calculated according to the waveform diagram of the conduction of the active shutter type 3D glasses and the complete dynamic scanning time of the LED display screen, so that the dynamic scanning time of the LED display screen is changed from being identical with the waveform time of the front part in the conduction waveform of the 3D glasses to being identical with the waveform time of the rear part in the conduction waveform of the 3D glasses, and the serious grille phenomenon caused by gradual change of the conduction waveform is effectively overcome.
It should be understood that the 3D glasses control method provided in this embodiment may be applied to the transmitting box in the above 3D glasses control system, and is used to transmit video data to the LED display device, calculate the phase shift t, perform the phase shift processing on the control signal, and then transmit the control signal to the wireless transmitter, and finally forward the control signal to the 3D glasses. In other implementations of this embodiment, the 3D glasses control method may also be applied to an intelligent device that establishes a communication connection with the sending box, where the intelligent device may be, for example, a ARM (Advanced RISC Machines) controller, FPGA (Field Programmable Gate Array) controller, soC (System on Chip) controller, DSP (Digital Signal Processing) controller, or MCU (Micorcontroller Unit) controller, or may be a desktop computer, a notebook computer, a tablet computer, a smart phone, a smart television, a personal digital assistant (Personal Digital Assistant, abbreviated as PDA), or other personal computers; the intelligent device calculates the phase shift t and then sends the phase shift t to the sending box, the sending box sends video data to the LED display device, the control signal is subjected to phase shift processing according to the phase shift t calculated by the intelligent device and then sent to the wireless transmitter, and the wireless transmitter forwards the control signal to the 3D glasses.
