Embodiment 1

[0037] Please refer to figure 1 , is a flow chart of the steps of a dust detection method based on motion detection provided by an embodiment of the present invention, including steps 101 to 103, and each step is specifically as follows:

[0038] In step 101, a binary image is generated by background modeling, and an object detection is performed on the binary image to obtain an object detection frame.

[0039] Specifically, please refer to figure 2 , is a principle flowchart of a dust detection method based on motion detection provided by an embodiment of the present invention. In order to judge whether there is dust in the picture, it is necessary to use the remaining two image processing technologies: background modeling and target detection, as follows: 1. Background modeling can maintain a long-term stable background image. When there are moving objects in the picture , you only need to compare the pixel difference between the moving object and the background image at ...

Embodiment 2

[0051] Accordingly, please refer to image 3 , is a schematic structural diagram of a dust detection device based on motion detection provided by another embodiment of the present invention, including a target detection module, a motion state module and a target determination module. The functions of each module are as follows:

[0052] The target detection module is configured to generate a binary image through background modeling, and perform target detection on the binary image to obtain a target detection frame.

[0053] The motion state module is used to judge the motion state of each object detection frame to obtain the motion object detection frame.

[0054] In this embodiment, this step includes: counting the number of moving pixels of each object detection frame, and determining that the object detection frame is a moving object detection frame when the number of moving pixels of the object detection frame reaches a preset number threshold.

[0055] The target determ...

Embodiment 3

[0058] An embodiment of the present invention also provides a computer-readable storage medium, the computer-readable storage medium includes a stored computer program; wherein, when running, the computer program controls the device where the computer-readable storage medium is located to execute the above-mentioned The dust detection method based on motion detection described in any embodiment.

Abstract

The invention discloses a dust detection method based on movement detection. The method comprises the steps: generating a binary image through background modeling, carrying out the target detection ofthe binary image, and obtaining a target detection frame; judging the motion state of each target detection frame to obtain a motion target detection frame; judging the attribute of the moving targetdetection box, and determining whether the target is dust or not; according to the technical scheme, under the condition that a machine learning method is not used, the background modeling and targetdetection technology is used for generating the target detection box, image processing is completed without being affected by resource occupation and the detection effect, then analysis is conductedaccording to the attribute of the moving object, and therefore whether the target is dust or not is judged.

Description

technical field [0001] The present invention relates to the technical field of video image processing, in particular to a dust detection method, device, medium and terminal equipment based on motion detection. Background technique [0002] At present, the intelligent IPC has played a pivotal role in the field of monitoring, especially in the late night monitoring, which has greatly liberated manpower. In the smart IPC, motion detection is one of the important functions. This algorithm can capture the changed part of the screen. If the area of ​​the changed part is large enough, an alarm will be triggered, so as to link sound alarm, light alarm or video recording and other follow-up Function. However, in the night vision scene, due to the reflection of infrared light on the dust, a small moving object will be formed in the picture. When the dust area is slightly larger or several dusts appear at the same time, the motion detection algorithm itself may It is impossible to ju...
