referring to fig. 1-2, an embodiment of the invention provides a laser night vision imaging device, which uses laser as a light source of the night vision imaging device to obtain image information of a deep sea environment or other areas with poor illumination environment. The laser night vision imaging device comprises a processor 100, a memory 200, a plurality of laser light source channels 700, a beam splitter 600, and a seed source laser 500, and further comprises a network interface (not shown) and a communication bus 300. The processor 100 and the memory 200 are connected by a communication bus 300. The memory 200 stores a laser light source control program configured to be executed by the processor 100, and the processor 100 executes the laser light source control program to implement the laser light source control method. The laser night vision imaging device takes laser as a night vision light source, and image information in a monitoring range is acquired through a plurality of imaging channels.

Specifically, the laser night vision imaging device comprises a plurality of laser light source channels 700, optical splitters 600, seed source lasers 500, an event triggering module 800 and a central control module 400, wherein the number of the optical splitters 600 is matched with that of the laser light source channels 700; the seed source laser 500 is connected with the central control module 400, and the seed source laser 500 is controlled by the central control module 400; the optical splitter 600 is connected with the seed source laser 500 to obtain a light source transmitted and input by the seed source laser 500; the optical splitter 600 is respectively connected to the laser light source channels 700 to transmit the light source obtained from the seed source laser 500 to the laser light source channels 700; the central control module 400 is connected to the event trigger module 800 and the laser light source channel 700, and the central control module 400 changes the working mode according to the feedback signals of the event trigger module 800 and the laser light source channel 700. The laser of the laser source channel 700 in the laser night vision imaging device is input into the beam splitter 600 by the seed laser source laser 500 and then transmitted to the laser source channel 700 to provide the seed light source. The laser light source channel 700 sends laser light through a built-in laser channel as a light supplement source for imaging of the channel, and an imaging unit (not shown) of the channel receives a spot echo optical signal reflected by the laser light to perform image processing, so as to obtain an image. Specifically, the laser night vision imaging device detects whether the central control module 400 has the laser light source channel 700 in the non-sleep state; if the laser source channel 700 in the non-sleep state exists, the seed source laser 500 is turned on.

referring to fig. 3, an embodiment of the present invention provides a laser light source control method, which is applied to the laser night vision imaging device, and the laser light source control method includes:

Step S101: acquiring detection signals of the plurality of laser light source channels;

step S103: judging whether a detection target exists in the monitoring range corresponding to the detection signal or not according to the detection signal; if there is no detection target signal, executing step S105; otherwise, go to step S109;

step S105: setting a laser light source channel corresponding to the monitoring range as a standby channel;

Step S107: controlling the standby channel to maintain a sleep mode; in addition, the method can be used for producing a composite material

Step S109: setting the channel as a first imaging channel;

step S111: and starting a laser light source of the first imaging channel to emit a light supplementing laser beam.

In this embodiment, the standby channel is the laser source channel 700 in which the detection target is not detected in the detection range, and the first imaging channel is the laser source channel 700 in which the detection target is detected. The laser light source channels 700 are all provided with laser channels for emitting light supplementing laser beams, and the light supplementing laser beams are light supplementing light sources of the laser night vision imaging device in the imaging process. Specifically, the supplementary light laser beam is emitted from a laser channel of the first imaging channel. The detection signal is obtained by detecting the environmental condition in the monitoring range by a detector arranged in the laser light source channel 700. The detector sends the detection signal to the central control module 400 of the laser night vision imaging device for processing and judgment. Specifically, when the detector does not detect that the detection target exists in the monitoring range, the laser light source channel 700 is kept in a sleep state, and power consumption is reduced. When the detector detects that a detection target exists in the monitoring range, the laser light source channel 700 is released from the sleep state, the laser light source channel 700 with the detection target in the monitoring range is set as a first imaging channel, and a light source of the first imaging channel is started to emit a light supplementing laser beam so as to provide a laser beam required by the first imaging channel.

further, referring to fig. 4, step S109 further includes:

step S201: the first imaging channel emits a light supplementing laser beam;

step S203: calculating the intensity of a light spot echo light signal returned by the emitted supplementary lighting laser beam of the first imaging channel from the detection target;

Step S205: detecting whether the intensity of the light spot echo light signal reaches a preset intensity; if the intensity of the light spot echo light signal cannot reach the preset intensity, executing step S207; otherwise, step S209 is executed

step S207: controlling the first imaging channel to set the laser light source channel as a standby channel; and controls the standby channel to enter a sleep mode.

step S209: and continuing to send the supplementary lighting laser beam.

in this embodiment, the light spot echo optical signal is an optical signal that is reflected back to the detector of the first imaging channel by the detection target irradiated by the supplementary light laser beam. It can be understood that, when a detection target exists in the monitoring range, the intensity of the reflected light spot echo light signal changes accordingly, and the detection target is stronger than the non-detection target. When the intensity of the spot echo optical signal is less than the preset intensity, the central control module 400 sets the laser light source channel 700 to continue the sleep state, so as to save the electric energy.

preferably, referring to fig. 5, the laser light source control method further includes:

Step S301: acquiring state information of the laser light source channels;

Step S303: judging whether the first imaging channel exists or not; if the first imaging channel does not exist, step S305 is executed: otherwise, continuing to execute step S303;

step S305: the laser night vision imaging device enters a global sleep mode.

Specifically, the global sleep mode is that the central control module 400, the seed source laser 500 and the laser source channel 700 of the laser night vision imaging device all maintain a low energy consumption state, and the state of the acquisition function of the laser source channel 700 for receiving the detection signal is maintained. It can be understood that, when the plurality of light source laser channels 700 are all in the sleep mode, in order to further reduce the energy consumption of the central control module 400 and the seed source laser 500, the central control module 400 and the seed source laser 500 are controlled to enter the sleep state, so as to achieve the global sleep state of the laser night vision imaging device.

Preferably, the laser light source control method further includes; and judging whether the detection target exists in the monitoring range of the trigger signal or the plurality of laser source channels 700, and if the detection target exists in the monitoring range of the trigger signal or the plurality of laser source channels 700, removing the global sleep mode by the laser night vision imaging device.

In this embodiment, the event triggering module 800 may be a hydrophone, an optical fiber sensing float device, or the like, to acquire a detection signal within a preset range of the laser night vision imaging device, so as to determine whether a detection target exists. Judging whether a trigger signal is detected; and generating the trigger signal, and then the laser night vision imaging device releases the global sleep mode. By receiving the trigger signal, the imaging dead angle of the laser light source channel 700 can be monitored. If the target appears at the dead angle position of the detection signal of the laser light source channel 700, the laser night vision imaging device is awakened, and image information in the monitoring range is obtained in real time. Specifically, the triggering manner of the triggering signal and the existence of the detection target in the monitoring range of the plurality of laser light source channels 700 may be one or a combination of level triggering and edge triggering, but is not limited to the two triggering manners.

In this embodiment, according to the detection signal of the channel, the laser night vision imaging device enters the whole full sleep state or the sleep state of the channel, so that the laser energy consumption can be controlled more flexibly, the laser energy consumption can be reduced, and the cruising ability of the laser night vision imaging device can be improved.
