[0046] Reference Figure 1 , Figure 1 This is an optional flowchart of a camera control method provided in an embodiment of the present application. The method may include but is not limited to steps S101 to S104:

[0047] Step S101, controlling the first camera to monitor the target area and identify abnormal events, and receiving abnormal event perception signals and corresponding abnormal event video data fed back by the first camera;

[0048] Step S102, in response to the abnormal event sensing signal, waking up the second camera, wherein the first camera and the second camera are integrated in the same multi-core heterogeneous system;

[0049] Step S103, controlling the awakened second camera to dynamically collect target area video data, receiving the target area video data, analyzing the target area video data and abnormal event video data, and generating abnormal event analysis results and abnormal event processing completion signals;

[0050] Step S104, controlling the second camera to enter a sleep state according to the abnormal event processing completion signal.

[0051] In some embodiments, before executing the above step S101, the first camera and the second camera are initialized, the first camera is put into working state, and the second camera is put into sleep state, wherein the first camera is an infrared shortwave camera or other type of sensor, and the second camera is a visible light camera. Specifically, a first camera control instruction is received, the first camera is powered, and the first camera is put into working state, a second camera control instruction is received, power supply to the second camera is stopped, and the second camera is put into sleep state.

[0052] Optionally, the wavelength of infrared shortwave can bypass fine particles in smoke, fog and haze. Compared with infrared medium wave and infrared long wave, infrared shortwave has better detail resolution and analysis capabilities, and can well identify objects in the target area, so that infrared shortwave can still achieve clear imaging of objects in the case of haze and heavy smoke, thereby effectively coping with image acquisition scenarios under various environmental conditions (including bad weather, insufficient lighting conditions, dust and smoke, etc.).

[0053] In the prior art, the control of multiple cameras is usually completed using multiple chips, and the chips are usually homogeneous chips. Each camera is controlled by an independent chip and a supporting hardware system, which is costly, complex in structure, and has low control efficiency. Based on this, the embodiment of the present application integrates the first camera and the second camera into the same multi-core heterogeneous system. The multi-core heterogeneous system includes a multi-core heterogeneous chip and a supporting hardware system. The multi-core heterogeneous system uses a single multi-core heterogeneous chip to achieve independent power supply for hardware domains and can independently run different operating systems in different domains. It is simple, efficient, and reduces costs.

[0054] In some embodiments, the first camera and the second camera are integrated into the same multi-core heterogeneous system. Specifically, the first camera is integrated into a low-power domain in the multi-core heterogeneous system, and the second camera is integrated into a high-power domain in the multi-core heterogeneous system. The low-power domain runs continuously, and when no abnormal event perception signal is received, the high-power domain is controlled to stop running, that is, power supply to the high-power domain is stopped, thereby controlling the second camera to enter a sleep state. When an abnormal event perception signal is received, the high-power domain is controlled to run and wake up the second camera.

[0055] In some embodiments, step S101 may include but is not limited to steps S201 to S203:

[0056] Step S201, when the first camera captures a dynamic living body in the target area, the first camera dynamically collects corresponding first abnormal video data and generates a first abnormal perception signal;

[0057] Step S202, when the first camera recognizes a preset chemical reagent in the target area, the first camera dynamically collects corresponding second abnormal video data and generates a second abnormal perception signal;

[0058] Step S203, when the first camera monitors that the current ambient temperature change value corresponding to the target area is greater than a given threshold, the first camera dynamically collects corresponding third abnormal video data and generates a third abnormal perception signal.

[0059] In some embodiments, the first camera can be used to detect colorless and odorless chemical reagents, dynamic living organisms, and ambient temperature. For example, the first camera is used to perform dynamic living organism detection on the target area. When it is determined that there is a living organism in the target area, a first abnormal perception signal is generated, wherein the living organism may include but is not limited to animals, human bodies and their tissues. When colorless and odorless chemical reagents appear in the target area, the first camera can capture the chemical reagents and image them. Different chemical reagents have different colors in the image, and then a corresponding second abnormal perception signal is generated. In addition, the first camera can continuously monitor the changes in ambient temperature of the target area, dynamically collect the ambient temperature according to a preset time interval, and when the ambient temperature of the target area is detected to be abnormal, it is determined that an abnormal event has occurred, and a corresponding third abnormal perception signal is generated. The ambient temperature abnormality includes an ambient temperature change value greater than a given threshold and a current ambient temperature greater than a given temperature threshold.

[0060] In step S102 of some embodiments, in response to the abnormal event perception signal, a camera wake-up instruction is dynamically generated, and the second camera is woken up according to the camera wake-up instruction.

[0061] In some embodiments, when the first camera generates an abnormal perception signal, the second camera is awakened, and the second camera is controlled to shoot the target area and collect corresponding target area video data.

[0062] In some embodiments, step S103 may include but is not limited to steps S301 to S303:

[0063] Step S301, controlling the awakened second camera to dynamically collect the target area video data, and transmitting the target area video data and the abnormal event video data to the intelligent analysis model;

[0064] Step S302, using an intelligent analysis model to perform event analysis based on the abnormal event video data and the target area video data to determine the abnormal event type and abnormal hazard level;

[0065] Step S303, binding the abnormal event type, abnormal hazard level, abnormal event video data and target area video data, generating abnormal event monitoring information and generating an abnormal event processing completion signal.

[0066] In some embodiments, after receiving the abnormal perception signal, the abnormal event video data dynamically uploaded by the first camera and the target area video data dynamically uploaded by the second camera are received. Optionally, the high power consumption domain in the above-mentioned multi-core heterogeneous system includes a neural processing unit (NPU, Neural Processing Unit), and the intelligent analysis model is integrated in the neural processing unit. The target area video data and the abnormal event video data are analyzed by the intelligent analysis model, and the abnormal event type and abnormal hazard level are output. The abnormal event type may include but is not limited to dynamic living bodies, temperature abnormalities, and reagent detection abnormalities.

[0067] In some embodiments, when the abnormal event processing completion signal is generated, the high power consumption domain is stopped from being powered, the second camera is put back into sleep mode, and the low power consumption domain is kept powered, so that the first camera remains in working state and continues to operate with low power consumption.

[0068] In some embodiments, the above method may further include steps S401 to S402:

[0069] Step S401, when the abnormal hazard level is greater than a preset level threshold, an abnormal alarm signal is generated;

[0070] Step S402, uploading abnormal event monitoring information and abnormal alarm signals to the monitoring platform.

[0071] In some embodiments, when the abnormal hazard level is greater than a preset level threshold, the abnormal event monitoring information and the abnormal alarm signal are reported to the monitoring platform, and the monitoring platform performs a secondary determination.
