The light control method is used on one side of a handle (such as the handle 20 shown in fig. 1) of a virtual reality device, and as can be seen in fig. 2, the light control method comprises the following steps:
and step S101, receiving a closing instruction.
When using a virtual reality device (e.g., the virtual reality device 100 shown in fig. 1), a user first turns on a helmet (e.g., the helmet 10 shown in fig. 1) and a handle; after the helmet is turned on, the image pickup device (e.g., the image pickup device 101 shown in fig. 1), the first processor (e.g., the first processor 102 shown in fig. 1), the first RTC unit (e.g., the first RTC unit 103 shown in fig. 1), and the first wireless communication unit (e.g., the first wireless communication unit 104 shown in fig. 1) of the helmet all enter an operating state; after the handle is turned on, the light source (for example, the light source 201 shown in fig. 1) of the handle is turned on, and the second processor (for example, the second processor 202 shown in fig. 2), the second RTC unit (for example, the second RTC unit 203 shown in fig. 1) and the second wireless communication unit (for example, the second wireless communication unit 204 shown in fig. 1) of the handle all enter an operating state.
And after the camera device enters a working state, shooting the light source according to a certain exposure period, and sending the image shot by each exposure to the first processor. The exposure period refers to the duration of an interval from the beginning of the exposure to the beginning of the next exposure. Each exposure period comprises an exposure duration and a processing duration, wherein the exposure duration refers to the duration of exposure duration in the exposure period, and the processing duration refers to the duration of processing the image shot by the current exposure.
The first processor determines that light of the light source can be shot according to an image shot by the camera device, then controls the helmet to send a closing instruction for closing the light source to the handle, and records time recorded in the first RTC unit at the current moment. The closing instruction includes the first time, an exposure period of the image pickup device, and an exposure duration of each exposure.

After the handle receives the closing instruction, the second processor of the handle responds to the closing instruction, controls the light source to be closed, and sets the reference time of the current time of the second RTC unit as the first time for timing.
And S103, adjusting the on-off state of the light source until the light source is turned off after a synchronous instruction is received, and recording the turn-on times of the light source.
After the first processor controls the helmet to send a closing instruction for closing the light source to the handle, when the fact that the light source is closed is determined to be shot by the camera device for the first time according to the image shot by the camera device is determined, a first target frame number of the camera device which shoots the light source to be closed at present is recorded; then, when it is determined that the light source is in an on state when the image pickup device shoots for the first time according to the image shot by the image pickup device, recording a second target frame number of the light source in the on state when the image pickup device shoots for the first time, and recording time recorded in the first RTC unit at the current time, in this embodiment of the present application, the time is recorded as a second time, that is, the second time is time when the image pickup device recorded in the helmet shoots for the first time and the light source is on after the helmet detects that the light source is off for the first time; then, determining the exposure times of the camera device according to the first target frame number and the second target frame number, wherein the exposure times refer to the total times of exposure of the camera device within the time length from the first detection that the helmet detects that the light source is turned off after the light source is turned off for the first time to the first detection that the light source is turned on later.
Further, the following formula may be used: and M2-M1+1, wherein M represents the exposure times, M1 represents the first target frame number, and M2 represents the second target frame number.
In addition, after the first processor controls the helmet to send a turn-off instruction for turning off the light source to the handle, when the light source is detected to be turned on for the first time after the light source is detected to be turned off for the first time according to an image shot by the camera device, the helmet is controlled to send a synchronous instruction to the handle, and the synchronous instruction comprises the exposure times and the second time.
After the second processor turns off the light source, the on-off state of the light source can be adjusted as follows: keeping the light source in a closed state, continuously presetting a first time length, and then starting the light source; keeping the light source in an opening state, continuously presetting a second time length, and then closing the light source; keeping the light source in a closed state, continuously presetting a third time length, and then starting the light source; and then, repeatedly executing the steps of keeping the light source in an opening state, continuously presetting a second time length, and then closing the light source until the light source is closed after a synchronous instruction is received. And the second processor records the turn-on times of the light source in the interval duration from the turning-off of the light source after the receiving of the turn-off instruction to the receiving of the synchronous instruction. Optionally, the turn-on times of the light source may be recorded as N, where N is a positive integer.
The first preset time length, the second preset time length and the third preset time length can be set according to actual needs. For example, the first preset time period may be set to 3Te + Tc, the second preset time period may be set to 2Tc, and the third preset time period may be set to Te — Tc, where Te represents the exposure period and Tc represents the exposure time period.
And step S104, determining timing delay between the helmet and the handle according to the first time, the exposure period, the exposure duration, the synchronous instruction and the opening times.

The obtaining of the exposure times and the second time included in the synchronization instruction may be implemented as follows: and the second processor of the handle analyzes the synchronous instruction and acquires the exposure times and the second time contained in the synchronous instruction.
Determining the timing time of the handle at the moment corresponding to the second time according to the first time, the exposure period, the exposure duration, the exposure times and the opening times, and can be realized according to the following modes: the following formula is used: and T is T1+ MTe + NTc, and the timing time of the handle is calculated and generated, wherein the timing time refers to the moment corresponding to the second time, and the time currently recorded by the second RTC unit in the handle, and the timing time cannot be read from the second RTC unit due to the communication delay between the helmet and the handle, and can be generated through calculation. Wherein T represents the timing time of the handle, T1 represents the first time, M represents the number of exposures, Te represents the exposure period, Tc represents the exposure time length, and N represents the number of opening times.
Determining a timing delay between the helmet and the handle according to the second time and the timing time can be realized by calculating and generating the timing delay between the helmet and the handle by using the following formula of △ T-T2-T, wherein △ T represents the timing delay, T2 represents the second time, and T represents the timing time.
And S105, synchronizing the timing of the helmet and the timing of the handle according to the timing delay.

And S106, adjusting the on-off state of the light source so that the light source is in an on state when the camera device is exposed and the light source is in an off state when the camera device is not exposed.
Referring to fig. 3, fig. 3 is a flowchart illustrating an implementation method of step S106 according to an embodiment of the present invention. As can be seen from fig. 3, in a specific implementation, step S106 may be implemented according to the method shown in fig. 3:
and step S201, acquiring target timing time in the handle.
The target timing time refers to any time recorded in the handle after the timing of the helmet and the timing of the handle are completed synchronously.
Step S202, determining a target timing duration according to the target timing time, the first time and the timing delay.
In a specific implementation, the step S202 may be implemented by calculating and generating the target timing duration by using the following formula T3-T4-T1- △ T, where T3 represents the target timing duration, T4 represents the target timing duration, T1 represents the first time, and △ T represents the timing delay.
Step S203, performing modular operation on the target timing duration and the exposure period to generate a remainder.
And step S204, calculating the difference value between the exposure period and the remainder.
Step S205, if the difference is greater than or equal to one-half of the exposure duration, turning on the light source at a first time corresponding to each exposure period, and turning off the light source at a second time corresponding to the exposure period.
The first time is the time before the exposure corresponding to any one exposure period starts and the time when the current exposure starts is separated by one half of the exposure time; the second time is a time separated by one half of the exposure time from the exposure ending time after the exposure corresponding to any one exposure period is ended.
