Embodiment 1

[0065] An implementable embodiment 1, based on the first implementable mode in step 201, the first information in this step is the channel state information sent by the WiFi module; wherein, the channel state information indicates the subcarrier carrying a specific message The rate of change of amplitude.

[0066] Therefore, the specific implementation of step 203 may be: according to the channel state information, it is determined that the rate of change of the amplitude of at least one subcarrier exceeds the first threshold, and when the pyroelectric infrared information is received, it is determined that there is a person in front of the camera.

[0067] Compared with the state when there is no person in front of the camera, when there is a person in front of the camera, according to the channel state information, it can be determined that at least one subcarrier has severe jitter (that is, the rate of change of the subcarrier amplitude exceeds the first threshold), image ...

Embodiment 2

[0074] A second implementable embodiment, based on the second implementable manner in step 201, the first information in this step is wireless signal strength information, where the wireless signal strength information indicates the Changes in correlation.

[0075] Therefore, step 203 refers to determining the correlation between the feature vectors within the set time range, and when the correlation between the first feature vector and a certain feature vector exceeds the second threshold, it is determined that there is a person in front of the camera.

[0076] In the above scheme, the scheme of determining whether there are people present through the information collected by the WiFi module can also be realized in the following ways:

[0077]For step 201, the WiFi module can also be set to receive WiFi information from a mobile device terminal (such as a mobile phone). When the MCU receives the WiFi information from a mobile device terminal (such as a mobile phone), it can b...

Abstract

The invention discloses a method and a device for improving camera wake-up accuracy and a readable storage medium, which are used for solving the problem of unnecessary energy consumption caused by false wake-up of a camera. The camera comprises a WiFi module, a pyroelectric infrared sensing module, a central processing unit and a control module. The method comprises the following steps: the control module receives first information; wherein the first information is sent by the WiFi module and is used for indicating whether a person appears in a set range or not; the control module receives pyroelectric infrared information; wherein the pyroelectric infrared information is sent by the pyroelectric infrared sensing module, and is used for indicating that the pyroelectric infrared sensing module detects that a person appears; within a set time range, when the control module receives the first information and the pyroelectric infrared information and the first information is matched with the pyroelectric infrared information, determining that a person appears in front of the camera; if so, sending second information to the central processing unit to wake up the camera.

Description

technical field [0001] The present application relates to the field of cameras, in particular to a method, device and readable storage medium for improving the accuracy of camera wake-up. Background technique [0002] Along with the rapid development of network technology, cameras including pyroelectric infrared sensors have entered people's lives. This kind of cameras can determine the presence of people through pyroelectric infrared sensors and start the cameras. In nature, any object higher than the absolute temperature (-273°C) will produce an infrared spectrum. The wavelength of the infrared energy spectrum released by different objects is different. The human body generally emits infrared rays with a specific wavelength of about 10um. Therefore, when a person appears in front of the camera, the pyroelectric infrared sensor (PIR) detects a thermal infrared spectrum different from the environment where the camera is located, and the spectrum is a specific wavelength arou...
