The system of claim 1, wherein the control device is specifically configured to determine a first time period for light emitted by the fill-in light to reach the camera according to a first distance between the fill-in light and the monitored target and a second distance between the camera and the monitored target.
3. The system of claim 1, wherein the control device is further configured to determine a second time period during which light emitted by the fill-in light reaches the monitoring target according to a first distance between the fill-in light and the monitoring target, and control a duration of light emitted by the fill-in light in each period to be a third time period, where the third time period is less than or equal to the second time period.
4. The system of claim 3, wherein the control device is further configured to control the camera to capture an image during each cycle for a fourth length of time, wherein the fourth length of time is less than or equal to the third length of time.
5. A method of monitoring, the method comprising:
the method comprises the steps that control equipment sends a first starting instruction to a light supplementing lamp, so that the light supplementing lamp emits light, and the current first moment is recorded;
and sending a second starting instruction to the camera after a predetermined first time length that the light emitted by the light supplement lamp reaches the camera from the first moment so that the camera collects images.
6. The method of claim 5, wherein determining a first length of time for light emitted by the fill light to reach a camera comprises:
and determining a first time length for the light emitted by the light supplementing lamp to reach the camera according to a first distance between the light supplementing lamp and the monitored target and a second distance between the camera and the monitored target.
7. The method of claim 5, wherein the method further comprises:
according to the first distance between the light supplement lamp and the monitored target, determining a second time length when the light emitted by the light supplement lamp reaches the monitored target, and controlling the duration of the light emitted by the light supplement lamp in each period to be a third time length, wherein the third time length is less than or equal to the second time length.
8. The method of claim 7, wherein the method further comprises:
and controlling the duration of the image acquisition of the camera in each period to be a fourth time length, wherein the fourth time length is less than or equal to the third time length.
9. A monitoring device, the device comprising:
the first sending module is used for sending a first starting instruction to the light supplementing lamp, enabling the light supplementing lamp to emit light and recording the current first moment;
and the second sending module is used for sending a second starting instruction to the camera from the first moment through a predetermined first time length for the light emitted by the light supplement lamp to reach the camera, so that the camera collects images.
10. The control equipment is characterized by comprising a processor, a communication interface, a memory and a communication bus, wherein the processor and the communication interface are used for realizing mutual communication by the memory through the communication bus;
a memory for storing a computer program;
a processor for implementing the method steps of any one of claims 5 to 8 when executing a program stored in the memory.
11. A computer-readable storage medium, characterized in that a computer program is stored in the computer-readable storage medium, which computer program, when being executed by a processor, carries out the method steps of any one of claims 5 to 8.
