Problems solved by technology

The disadvantage of this scheme is that this scheme mainly relies on the background difference to detect the contour lines of objects that may exist in the car, and then further uses the contour line information to analyze whether there are objects in the car
The disadvantage of this scheme is that the detected objects cannot distinguish whether they are human bodies or other objects, so it is impossible to identify whether there are left objects in the elevator

Embodiment 1

[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 left objects in the elevator. The unit can use monitoring cameras, industrial cameras and other image acquisition equipment. The human body signal acquisition unit can use PIR (Passive Infrared) sensors, micro-blog sensors and other human body sensing devices. The button signal acquisition 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, so as to obtain the floor information corresponding to the button. When the button signal acquisition unit is directly integrated on the button control board, it only needs to A transmitter that can send button trigger signals to the outside can be added to the control board. The transmitter c...

Embodiment 2

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

[0040] like figure 1 As shown, the automatic detection method of the present 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 a person in the elevator car, and sends it to the leftover object analysis unit;

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

[0043] The full image information refers to the image information in all field of view captured downward from the angle of the video acquisition unit.

[0044] (3) The button signal acquisition 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 a...

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...
