Abstract
The invention belongs to build auxiliary facility technical field.Propose the lift car overload detecting method based on image procossing, comprising the following steps: step 1: acquiring background image by camera, and establish background edge model；Step 2: extracting human body edge using the method for building background edge, to occupant's number and number is separated, be stored in different images respectively according to extracted edge contour area；Step 3: tracking using moving image to each occupant, and its direction of motion is judged, so that it is determined that the number of people entering of elevator occupant；Step 4: subtracting the occupant's number for walking out lift car with the occupant's number for entering lift car, occupant's number in current car is obtained；Step 5: issuing alarm signal when occupant's number is more than the maximum carrying capacity of elevator.The present invention carries out accurate judgement using occupant number of the image processing method to disengaging elevator, and compared to existing gravity sensor detection method, reliability is stronger, and installation is more convenient.
Description
Technical field
The invention belongs to build the overload of auxiliary facility technical field, especially elevator detection.
Background technique
Elevator is widely used in skyscraper, and the security performance of elevator should not be overlooked.Elevator overload alarm is elevator day
An often important content in maintenance.Elevator overload detection at present comes generally by gravity sensor to super in lift car
Load state is monitored alarm to ensure boarding safety.However due to elevator long-play, frequent operation, external environment
The a variety of causes such as factor, ageing equipment or maintenance personnel's maloperation, are likely to result in gravity sensor and go wrong, thus cause
Serious accident.
Summary of the invention
To solve problems of the prior art, the lift car overload based on image procossing that the present invention provides a kind of
Detection method has many advantages, such as detection accuracy height, convenient for installation and maintenance.
To achieve the above object, the technical solution adopted by the present invention are as follows: it is super to propose the lift car based on image procossing
Carry detection method, it is characterised in that: the following steps are included:
Step 1: acquiring background image by camera, and establish background edge model；
Step 2: human body edge is extracted using the method for building background edge, according to extracted edge contour area to occupant people
Number simultaneously separates number, is stored in different images respectively；
Step 3: tracking using moving image to each occupant, and judge its direction of motion, so that it is determined that elevator occupant
Number of people entering；
Step 4: subtracting the occupant's number for walking out lift car with the occupant's number for entering lift car, obtain in current car
Occupant's number；
Step 5: issuing alarm signal when occupant's number is more than the maximum carrying capacity of elevator.
Further, the camera uses low-light (level) camera, and the camera is being installed on lift car doorway just
At top position.
The beneficial effects of the present invention are embodied in: accurately sentenced using occupant number of the image processing method to disengaging elevator
It is disconnected, and overload early warning is carried out, gravity sensor detection method compared with the prior art, reliability is stronger, and installation is more convenient.
Specific embodiment
The present invention is described in detail below.
Embodiment one:
Lift car overload detecting method proposed by the present invention based on image procossing, comprising the following steps:
Step 1: acquiring background image by camera, and establish background edge model；
Step 2: human body edge is extracted using the method for building background edge, according to extracted edge contour area to occupant people
Number simultaneously separates number, is stored in different images respectively；
Step 3: tracking using moving image to each occupant, and judge its direction of motion, so that it is determined that elevator occupant
Number of people entering；
Step 4: subtracting the occupant's number for walking out lift car with the occupant's number for entering lift car, obtain in current car
Occupant's number；
Step 5: issuing alarm signal when occupant's number is more than the maximum carrying capacity of elevator.
Wherein, camera uses low-light (level) camera, and the camera is installed on the position directly above on lift car doorway
Place.
The present invention carries out accurate judgement using occupant number of the image processing method to disengaging elevator and carries out overload early warning,
Gravity sensor detection method compared with the prior art, reliability is stronger, and installation is more convenient.
