Because the display time of display screen is less than the control signal valid period of initiative shutter-type 3D glasses, the shutter of 3D glasses switches on the process that becomes gradually again moreover, consequently can appear the grid phenomenon often, leads to user experience not good.
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 are used in cooperation with an LED display screen to effectively alleviate a grid phenomenon occurring in the existing 3D glasses control, and improve user experience. In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention are further described in detail by the following embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
fig. 2 is a schematic structural diagram of a 3D glasses control system suitable for an LED display device according to an embodiment of the present invention. 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 obtains 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. Note that 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, etc.; the 3D vision device 24 is, for example, active shutter type 3D glasses, and the embodiment is not particularly limited.
The transmitting box 21 calculates a first path delay time t1 of the video data from the transmitting box 21 to the LED display device 22, and calculates a second path delay time t1 of the control signal from the transmitting box 21 to the 3D vision device 24. It should be understood that the transmission of both video data and control signals will generate a path delay time, which can be calculated based on the time difference between the signal arrival time stamp and the signal emission time stamp, or can be estimated according to the transmission speed and the transmission distance, which is not limited in this embodiment.
In the present embodiment, in addition to the influence of the path delay time, the phase shift time t3 required by the shutter control signal of the 3D vision device 24 to adapt to the dynamic scanning of the LED display device 22 and avoid the grid phenomenon is also considered. Taking the active shutter type 3D glasses as the 3D vision device as an example, 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 (i.e. the time corresponding to a complete control signal waveform), and the conduction of the glasses shutter is a gradual change process, in order to alleviate the occurrence of the grid 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 shutter and the one-time complete dynamic scanning time of the LED display screen, so that the dynamic scanning time of the LED display screen is changed from the original waveform time which is matched with the front part in the conduction waveform of the 3D glasses shutter to the waveform time which is matched with the rear part in the conduction waveform of the 3D glasses shutter, thereby effectively overcoming the serious grid phenomenon caused by the gradual change of the conduction waveform.
After the first path delay time t1, the second path delay time t1 and the phase shift time t3 are respectively calculated, the phase shift t to be performed by the control signal sent by the sender box 21 is obtained as t1-t2+ t 3. That is, the total phase shift to be performed by the control signal not only takes into account 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 takes into account the phase shift time t3 obtained based on the waveform diagram of the glasses shutter conduction and one complete dynamic scanning time of the LED display screen.
The transmitting box 21 performs phase shift t processing on the control signal and 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 technical solutions adjust the control signal only by measuring the opening time of the 3D glasses shutter, and some existing technical solutions send the video data and the control signal from the sending box synchronously without considering the problem of path delay, and these existing technical solutions all have obvious disadvantages and still cause the occurrence of the grid phenomenon. The phase shift t of the sending box to the control signal not only considers the path delay of the video data and the control signal, but also considers the phase shift of the control signal of the 3D glasses shutter to adapt to the dynamic scanning of the LED display screen, thereby avoiding the grid phenomenon and fundamentally relieving the grid phenomenon.
Example two:
as shown in fig. 4, a flowchart of a 3D glasses control method suitable for an LED display device in an embodiment of the present invention is shown, and the method mainly includes the following steps.
In step S41, a video source is acquired.
Step S42, sending the video data to the LED display device.
Step S43, sending the phase-shifted control signal to the 3D vision equipment; it should be noted that, the sending of the control signal to the 3D vision device in this embodiment may refer to sending the control signal directly to the 3D vision device, or may refer to forwarding the control signal to the 3D vision device after passing through another device (such as a wireless transmitter), which is not limited in this embodiment.
In the present 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 the video data to the LED display device; let the first path delay time be t 1.
Step S432 of calculating a second path delay time generated by transmitting the control signal to the 3D vision device; let the second path delay time be t 2.
It should be understood that the transmission of both video data and control signals will generate a path delay time, which can be calculated based on the time difference between the signal arrival time stamp and the signal emission time stamp, or can be estimated according to the transmission speed and the 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 visual device and one-time complete dynamic scanning time of the LED display device; let the first phase shift time be t 3.
Step S444 of 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 and second path delay times and the first phase shift time; let the second phase shift time be t, then the calculation formula for t can be expressed as t1-t2+ t 3.
In this embodiment, in addition to the influence of the path delay time, the phase shift time t3 required by the shutter control signal of the 3D vision device to adapt to the dynamic scanning of the LED display device and avoid the grid phenomenon is also considered. Taking active shutter type 3D glasses as an example of 3D vision equipment, 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 (i.e. the time corresponding to a complete control signal waveform), and the conduction of the glasses shutter is a gradual change process, in order to alleviate the occurrence of the grid phenomenon, a 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 shutter and one complete dynamic scanning time of the LED display screen, so that the dynamic scanning time of the LED display screen is changed from the original time matched with the waveform time of the front part in the conduction waveform of the 3D glasses shutter to the time matched with the waveform time of the rear part in the conduction waveform of the 3D glasses shutter, thereby effectively overcoming the serious grid phenomenon caused by the gradual change of the conduction waveform.
It should be understood that the 3D glasses control method provided by 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 phase shift processing on the control signal, transmit the control signal to the wireless transmitter, and finally forward the control signal to the 3D glasses. In some other embodiments of this embodiment, the 3D glasses control method may also be applied to an intelligent device that establishes a communication connection relationship with the sender box, where the intelligent device may be, for example, an arm (advanced RISC machines) controller, an fpga (field Programmable Gate array) controller, an soc (system on chip) controller, a dsp (Digital Signal processing) controller, or an mcu (micro controller unit) controller, or a Personal computer such as a desktop computer, a notebook computer, a tablet computer, a smart phone, a smart television, and a Personal Digital Assistant (PDA); 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 sender, and then the wireless sender forwards the control signal to the 3D glasses.
