Embodiment 1
[0064] Please refer to figure 1 Shown, a kind of social distance keeps reminding method, comprises:
[0065] Obtain the ambient temperature signal and the surface temperature signal of the detection object;
[0066] judging whether the detection object is a human body according to the surface temperature signal and the ambient temperature signal of the detection object;
[0067] Acquiring a distance signal of the detected object;
[0068] Judging whether the social distance of the detected object is less than a distance threshold (such as 1 meter) according to the distance signal;
[0069] If it is judged that the detected object is a human body and the social distance is smaller than a distance threshold, a reminder message that the social distance is too small is output.
[0070] Wherein, the above-mentioned acquisition of the temperature signal and the acquisition of the distance signal are performed in no particular order.
[0071] Wherein, the determining whether the ...
Embodiment 2
[0079] Please refer to figure 2 Shown, a kind of social distance keeps reminding device, comprises:
[0080] The temperature detection module is used to obtain the surface temperature signal and the ambient temperature signal of the detection object;
[0081] a distance detection module, configured to obtain a distance signal of the detection object;
[0082] The condition judging module is used to judge whether the detection object is a human body, and whether the social distance of the detection object is less than a distance threshold;
[0083] The reminder alarm module, when the detected object is judged to be a human body and the social distance is less than the distance threshold, then outputs a reminder alarm message that the social distance is too small.
[0084] Wherein, also comprise sound and / or vibration output unit and light and / or laser output unit, described sound and / or vibration output unit and light and / or laser output unit are initial state of standby, wh...
Embodiment 3
[0091] The difference between this embodiment and Embodiment 2 is that it further includes a peripheral contour detection module, and the peripheral contour detection module is used to obtain the peripheral contour of the detection object;
[0092] The condition judging module is also used for judging whether the outer contour of the detected object is a human body.
[0093] Preferably, the outer contour detection module is an infrared camera, and according to the acquired detection image of the infrared camera, combined with a human body contour detection algorithm, it can be judged whether it is a human body.
[0094] For example, the temperature detection module is equipped with a multi-point lattice temperature sensor and an infraredtemperature measurement sensor. The multi-point lattice temperature sensor is also used as a peripheral contour detection module, and the infrared temperature measurement sensor is used to read the current ambient temperature. The temperature ...

Abstract
The invention relates to a social distance keeping reminding method. The method comprises the following steps: acquiring an environment temperature signal and a surface temperature signal of a detection object; judging whether the detected object is a human body or not according to the surface temperature signal and the environment temperature signal of the detected object; acquiring a distance signal of the detected object; judging whether the social distance of the detection object is smaller than a distance threshold according to the distance signal; if it is judged that the detection object is the human body and the social distance is smaller than the distance threshold value, reminding information that the social distance is too small is output. According to the technical scheme provided by the invention, the reminding information that the social distance is too small is output only when the detection object is judged to be the human body and the social distance is smaller than the distance threshold value, so that the scheme is relatively good in stability and cannot give an alarm against the object. Besides, the user only needs to wear the device of the scheme, the device can be used in all dense crowds, all users do not need to wear the same sensor to calculate the distance between the users, and therefore the popularization cost of the scheme is extremely low.
Description
technical field [0001] The present invention relates to the field of social technology, in particular to a social distance maintenance reminder method, device and medium. Background technique [0002] Maintaining a reasonable social distance between people can not only effectively prevent the occurrence of stampede accidents, but also prevent the close-range droplet transmission of the virus during the epidemic, thereby reducing the risk of respiratory infectious diseases. [0003] At present, there are many social distance detection methods and alarm technologies, but the existing social distance detection and alarm methods require all detected users to wear a sensor, and the social distance is calculated by electromagnetic wave signals sent between the sensors worn by each user; The application cost of this type of method is too high, and all users in the application scenario must wear the sensor before it can be popularized. [0004] Therefore, how to design a low-cost s...
