Example Embodiment

[0036] Embodiment 1, an automatic detection system for elevator leftovers.

[0037] The automatic detection system of this embodiment is used to detect whether there are any leftovers in the elevator. The automatic detection system includes a video acquisition unit, a human body signal acquisition unit, a button signal acquisition unit, a leftover analysis unit and an alarm logic analysis unit, and video acquisition The unit can use image collection equipment such as surveillance cameras and industrial cameras. The human body signal collection unit can use PIR (Passive Infrared) sensors, microblog sensors and other human body sensing devices. The button signal collection unit includes the button control panel and button touch screen in the elevator car. , Or a trigger signal acquisition device connected to the button control board and the button touch screen, used to collect button trigger information, thereby obtaining the floor information corresponding to the button. When the b...

Example Embodiment

[0039] Embodiment 2, an automatic detection method of elevator leftovers.

[0040] Such as figure 1 As shown, the automatic detection method of this embodiment applies the detection system in embodiment 1, and includes the following steps:

[0041] (1) The human body signal acquisition unit collects the signal of whether there is anyone in the elevator car and sends it to the leftover analysis unit;

[0042] (2) The video acquisition unit collects the door status information of the elevator car and the overall picture information in the elevator car, and sends it to the leftover analysis unit;

[0043] The full-image information refers to the image information in all the field of view shot down from the perspective of the video capture unit.

[0044] (3) The button signal collection unit collects the button trigger information on the button panel in the elevator car and the corresponding floor in real time, and sends the information to the alarm logic analysis unit;

[0045] (4) The left...

Abstract

The invention provides an automatic detection system for elevator left objects. The automatic detection system comprises a video collection unit, a human body signal collection unit, a button signal collection unit, a left object analysis unit and an alarming logic analysis unit. The video collection unit and the human body signal collection unit are connected to the left object analysis unit andsend the collected information to the left object analysis unit. The left object analysis unit is connected with the alarming logic analysis unit, the button signal collection unit is connected with the alarming logic analysis unit, and the alarming logic analysis unit sends alarm signals to the property management department. The invention further provides an automatic detection method for the elevator left objects. By means of the automatic detection system and method for the elevator left objects, the left object detection accuracy rate is improved, the state that people are in an elevatorcar is excluded in the detection range, unnecessary detection is avoided, the resource is saved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of video detection in an elevator car, in particular to the detection technology of elevator leftovers. Background technique [0002] Taking the elevator is something that many people have to experience every day. Some people will leave things in the elevator due to carelessness. Since the elevator is a public tool and is running at any time, the leftovers may be picked up by others, causing unnecessary damage to the owner. property damage. [0003] There are also some schemes about object detection in elevators in the prior art. For example, Chinese patent CN2006800281691 discloses an object detection device for elevators. The object detection device has: an image acquisition unit, which acquires the current image captured by the photography department and a background image captured when there is no detection object in the monitoring area; a background contour line information extraction unit that extract...
