A method, device and system for moving object detection

Abstract

The invention discloses a moving object detection method, device and system. The method specifically includes the steps that light intensity change information of at least one ground area is obtained; whether a moving object exists in the ground area or not is determined according to the light intensity change information; if the moving object exists in the ground area, position information corresponding to the moving object is determined according to the coordinate of the ground area. By means of the method, an existing detection scheme can be optimized, so that the detection scheme is simpler and safer.

Description

technical field [0001] The present invention relates to the field of smart home technology, in particular to a method, device and system for moving object detection. Background technique [0002] Traditional human activity detection methods usually include camera detection methods and detection methods based on electronic ground sensors. Wherein, the camera detection method is to take pictures or videos of at least one moving object through the camera, so that the processor can determine the activity information of the at least one moving object according to the pictures and videos of the at least one moving object. The detection method based on the electronic ground sensor is to detect the magnitude of the pressure through the ground sensor based on electronic technology such as voltage, and then extract the activity information of the moving object. [0003] However, in some scenes, it is not necessary to know the exact activity information of the moving objects, but only...

Problems solved by technology

At this time, if the camera detection method is used, the acquired video and images need to be processed in real time, which requires a large communication bandwidth and calculation amount. At the same time, due to the influence of ambient light and obstacles, the calculation complexity is further increased. improve

If the detection method based on electronic ground sensors is used, due to the relatively large volume of the piezoelectric sensor, the existing scheme requires a large number of sensors, which makes it difficult to network the piezoelectric sensor and apply it in a large area. After the code of the conductive element array is determined, the The encoding is difficult to change, so the application scenarios of the above detection methods are limited

At the same time, when using piezoelectric sensors, it is necessary to always pay attention to the response of water leakage and leakage to piezoelectric sensors, which also limits the application of piezoelectric sensors.
