Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0021] Such as figure 1 As shown, the device of the present invention includes an interactive device 1, an infrared sensor 2 and a camera 3; the infrared sensor 2 is arranged on the interactive device 1 and forms a fan-shaped infrared sensing area with a radius of half a meter in front of the interactive device 1; The camera 3 is set directly above the interactive device 1 to monitor the image in front of the device; the shooting angle of the camera 3 coincides with the infrared sensor 2 . The signal output end of the infrared sensor 2 is connected to the signal input end of the camera 3, and the signal output end of the camera 3 is connected to and controls the control end of the interactive device 1, which is a digital signage.

[0022] Such as figure 2 As shown, in this scene, in order to detect people passing by in front of the digital ...

Abstract

The invention discloses a short-distance motion detection device and method. The device comprises interactive equipment, an infrared sensor and a camera; the infrared sensor is arranged on the interactive equipment; furthermore, a fan-shaped infrared sensing area is formed in the front of the interactive equipment; the camera is right above the interactive equipment and used for monitoring an image in the front of the equipment; the signal output end of the infrared sensor is connected to the signal input end of the camera; and the signal output end of the camera is connected to and controls the control end of the interactive equipment. The device disclosed by the invention is simple in structure; the method for detecting motion in a short-distance range is provided; therefore, disturbance of a background in the distance can be effectively removed; the false alarm rate can be reduced; and the method can be used in a digital name plate system and used as a triggering condition of entering an operation interface or cutting in a prior advertisement.

Description

technical field [0001] The invention relates to a motion detection method, in particular to a motion detection method suitable for close-range operation equipment. Background technique [0002] With the development of science and technology, the application range of motion detection is becoming wider and wider, and it has relatively mature applications in intelligent monitoring and intrusion detection. In recent years, with the rise of smart homes and digital signage, motion detection has been applied to these short-range interactive devices to wake up the devices and achieve interaction. [0003] At present, motion detection mainly uses two kinds of detection equipment, infrared sensor and camera. The infrared sensor is easy to use and low in cost, but its detection range is limited, and it is impossible to identify whether the moving object is a human body; the camera mainly uses image analysis to determine whether there is an object in motion. , three methods are mainly ...
