[0031] figure 1 It is the flow chart of the first embodiment of the dynamic image recognition control method, including:

[0032] 101. Acquire a dynamic image in an image data buffer.

[0033] It should be noted that the dynamic images are sequentially stored in the image data buffer in the form of frames, wherein the dynamic image collected in real time is set as the current dynamic image, and the previous dynamic image of the current dynamic image is set as the current dynamic image. The image is set as the front dynamic image.

[0034] 102. Extract a moving target in the current dynamic image.

[0035] The current dynamic image includes a moving target and a background image, wherein the background image does not change in the short term, while the moving target moves in real time, so the moving target can be separated from the background image to effectively extract the The moving target in the current dynamic image.

[0036] 103. Track the moving object and determine ...

[0041] figure 2 It is a flow chart of the second embodiment of the dynamic image recognition control method, including:

[0042] 201. Acquire a dynamic image in an image data buffer.

[0043] Wherein, the dynamic image collected in real time is set as the current dynamic image, and the previous dynamic image of the current dynamic image is set as the preceding dynamic image.

[0044] 202. Determine a foreground object according to the current dynamic image and the background image.

[0045] During the working process, the pixel of the current dynamic image is subtracted from the corresponding pixel in the background image, and when the absolute value of the obtained difference is greater than the preset pixel, it is judged as the pixel of the foreground object.

[0046] It should be noted that the current dynamic image includes a foreground object and a background image, wherein the background image does not change in a short period of time, and the foreground object may be...

[0061] image 3 It is the flow chart of the third embodiment of the dynamic image recognition control method, including:

[0062] 301. Acquire a dynamic image in an image data buffer.

[0063] 302. Perform brightness normalization processing on the current dynamic image.

[0064] It should be noted that the current dynamic image stored in the image data buffer is a grayscale image, therefore, the current dynamic image needs to be processed to normalize the brightness, and each part of the current dynamic image is equalized and normalized to The same brightness state, so that the light intensity does not affect future judgments.

[0065] 303. Determine a foreground object according to the current dynamic image and the background image.

[0066] 304. Perform binarization processing on the foreground object and determine connected regions.

[0067] Through binarization processing, the foreground object presents an obvious black and white effect, effectively highlights the out...

Abstract

The invention discloses a dynamic image recognition control method, which comprises the following steps of: acquiring a dynamic image in an image data register; extracting a moving target in the current dynamic image; and tracking the moving target and judging whether the moving target has the tendency of moving toward an elevator door, if so, generating control information of opening the elevator door. The invention also discloses a dynamic image recognition control device and a dynamic image recognition control device. The dynamic image recognition control method is easy to operate and convenient to use, any external equipment is not required, a dynamic image in a certain area outside the elevator sedan can be detected, the moving target in the dynamic image is extracted, analyzed and tracked, and whether the moving target has the tendency of moving toward the elevator door is judged according to the motion trail of the moving target so as to control delayed closing or reopening of the elevator door, so that the opening and closing of the elevator door are intelligent, and the user requirements are met.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a dynamic image recognition control method, device and system. Background technique [0002] The basic control of the elevator includes the control finger box in the car and the call finger box outside the hall. The floor control box in the car is used to send instructions in the car, command the elevator to start and stop at the floor, and display the running direction and location of the elevator; the hall call floor box is a call for people who are preparing to take the elevator outside the hall. The device of the elevator, which has up and down buttons, can also display the current position and running direction of the elevator. In addition, there is generally a near-door protection device on the elevator door. The elevator door safety touch panel drives the interlock switch or photoelectric sensor, and the inductive near-door sensor controls the door opening and closing m...
