The processing module is used as a core computing module, and specifically can adopt an A64 microprocessor based on ARM Cortex-A53, wherein the maximum working frequency of the microprocessor is 1.15GHz, and the memory is 1G. The human shape detection model can be pre-stored in the processing module and can be obtained by training through a deep learning method based on a convolutional neural network, the logarithmic mean omission factor of the deep learning method is as low as 7%, the anti-interference capability is high, shielding and background can be well distinguished, the detection precision is high, the specific learning training method can be realized by referring to the prior art, and limitation is not required.

When convolution calculation is carried out, a multi-core parallel algorithm and acceleration of an instruction set can be utilized, and a fast convolution algorithm is adopted, so that the time complexity of a convolution process is reduced. Because the convolution calculations are independent from each other, the multi-core parallel operation and the fast convolution operation can be performed on the convolution operations by using a pthreadpool thread pool technology and an nnpack library function of a Facebook fast convolution calculation library. In addition, the A64 microprocessor supports the NEON instruction set, and therefore can perform single-core parallel operations on single instruction multiple data streams, thereby further speeding up the computation.
With further reference to fig. 2, the human-shaped detection module specifically includes an infrared pyroelectric sensor, and the infrared pyroelectric sensor is connected to the processing module; the infrared pyroelectric sensor is used for detecting human shape in a space range to be detected by detecting infrared rays emitted by a human body.

For example, if the human shape in the human shape detection result is far, or the occupation ratio in the whole image is small, the focus of the infrared camera can be shortened through the focusing module, so that the visual field can be expanded, and the human shape target in the image is clearer. Through the focusing module, the localized real-time high-precision human shape detection can be realized, so that the situations of false alarm and missed alarm can be reduced when the focusing module is applied to an alarm function, and the monitoring of security and protection is facilitated.

Wherein, the first resolution is lower than the second resolution, the power consumption of the first stage is the lowest, the resolution of the second stage is lower than the third stage, but the detection speed is higher than the third stage.
With further reference to fig. 3, assuming that the humanoid detection control device is initially in stage one, the preset conditions for the device to perform state transition among three stages are specifically:

and 7, when no human is detected by using high resolution in the space range to be detected, the human-shaped detection device enters a first stage, namely the infrared camera is closed.
