201. the light intensity of the environment where the three-source camera is located is detected through a photosensitive sensor.
In this embodiment, the three-source camera detects the light intensity of the surrounding environment through the photosensitive sensor, where the surrounding environment is the environment around the photosensitive sensor, the photosensitive sensor may be installed at any position outside the three-source camera as long as the function of detecting the light intensity is implemented, and the specific position of the photosensitive sensor on the three-source camera is not limited here.
202. And if the light intensity is less than the threshold value, the infrared lamp is started.
In this embodiment, if the acquired light intensity is less than the threshold, it is proved that the environment is dark, and an infrared lamp needs to be turned on to assist imaging, where the light intensity may be represented by a photosensitive value.
If the light intensity is not less than the threshold value, the environment is brighter at the moment, and the infrared lamp does not need to be turned on.
203. And carrying out movement detection according to the images acquired by the three-source camera to obtain a movement detection result.
In this embodiment, the motion detection is performed according to the images acquired by the three-source camera to obtain a motion detection result, specifically, the images of the two frames obtained by the three-source camera are compared, if it is known from the comparison result that there is a difference in partial regions in the images of the two frames, it is proved that there is a moving object in the image at this time, and if the images of the two frames are consistent, it is proved that there is no moving object in the image at this time.
204. And performing living body detection according to the PIR to obtain a living body result.
In this embodiment, whether or not living bodies are present in the surroundings is detected by the PIR, and since the human body has a constant body temperature, generally 37 degrees, infrared rays having a specific wavelength of about 10 μm are emitted, and the PIR attached to the three-source camera operates with infrared rays having a wavelength of about 10 μm emitted from the human body, and specifically, infrared rays having a wavelength of about 10 μm emitted from the human body are concentrated on the infrared sensor source after being intensified by the fresnel filter. The infrared induction source usually adopts a pyroelectric element, the pyroelectric element loses charge balance when receiving the change of the infrared radiation temperature of a human body, charges are released outwards, a subsequent circuit can generate an alarm signal after being checked, and the generation of the alarm signal indicates the existence of a living body.
The specific position times of the PIR on the three-source camera are not limited.
It should be noted that step 204 may also be executed before step 203, and the execution order of step 203 and step 204 is not limited herein.
205. And judging whether to start the lighting function according to the mobile detection result and the living body result.

If no moving object exists in the acquired image according to the movement detection result or no living body exists in the environment where the three-source camera is located according to the living body result, the lighting function does not need to be started at the moment.
This step can be implemented on the main control unit 101 in the three-source camera.
206. And if the lighting function is started, the white light lamp or the warm light lamp is selected to be started according to the preset mode.
If it is found that there is a moving object in the image at this time and there is a living object in the environment where the three-source camera is located according to step 205, then a white light lamp or a warm light lamp is turned on according to a preset mode, wherein the preset mode includes a arming mode or a non-arming mode.
Specifically, the method comprises the following steps: when the motion detection and the PIR are triggered simultaneously (namely, when a moving object exists in an acquired image according to a motion detection result and a living body exists in the environment where the three-source camera is located according to a living body result), the warning white light lamp is normally turned on until an alarm is turned off.
If the preset mode is the defense deploying mode, the white light lamp is started;
wherein, when the motion detection and the PIR are triggered simultaneously, the warm light is on. And 5s after the trigger source is released, the warm light lamp is turned off.
And if the preset mode is the non-defense mode, starting the warm light lamp.
It should be noted that, a user may set a preset mode on an Application (App, Application) of the terminal, that is, whether the three-source camera is in the defense deployment mode or not, which may be determined by the user according to a specific environment condition, and if the environment or the time period in which the three-source camera is located is unsafe, the preset mode needs to be set as the defense deployment mode, so that the white light lamp is turned on when the three-source camera has a moving living body, which may not only serve as an illumination function, but also serve as a warning function. If the environment or the time period of the three-source camera is safe, the preset mode is set to be the non-defense mode, so that the three-source camera can start the warm light when a moving living body exists, the illumination function can be achieved at the moment, the warm light is not dazzling, and the use experience of the camera product in a dark light environment is not influenced. In the scheme of the invention, the warm light lamp and the white light lamp with the alarm function can be effectively separated, and the user experience is good.
Specifically, the three-source camera receives a defense setting instruction sent by a terminal, and the defense setting instruction is used for indicating that the three-source camera is set to be in a defense setting mode or a non-defense setting mode.
It should be noted that, in an embodiment, the three-source camera may receive a switch instruction of the warm light of the terminal, and then determine the on-off state of the warm light according to the switch instruction, that is, at this time, the warm light may be directly turned on or turned off through the APP end of the mobile phone, without considering the environmental factors around the three-source camera.
