Description

Technical Field

[0001] The present invention relates to the field of data analysis, and in particular to a visual monitoring data acquisition and analysis device. Background Art

[0002] The beach is formed by the accumulation of sand on the land along the waterside or the flat land above the water surface in the water. The formation of the beach is due to the erosion of the rocks on the land by seawater. The components in the rocks that are more soluble in water, such as limestone, are lost with the seawater, while the sand, which is very hard quartz, will be retained. Due to the impact of seawater and weathering, over a long period of time, large pieces of quartz will gradually break into small pieces, and finally become small grains of sand; secondly, the soil on the seabed is exposed to the sea surface during the movement of the earth's crust, and some coral reefs and shells are also exposed. Under the impact and grinding of the waves, they become tiny particles, which are carried to the vicinity of the land by the waves. Due to the exhaustion of kinetic energy, they are deposited as beaches.

[0003] Visual monitoring of beaches is mainly used to identify safety accidents on the beach, so that response personnel can take quick measures to deal with them. However, the most realistic picture of the beach scene is the sensed image of the image sensor unit when the shooting mechanism is shooting. However, due to compression convenience or image quality optimization, the sensed image will be processed during the image transmission process, resulting in the actual image being different from the original sensed image, which can easily cause deviations in the identification of safety accidents on the beach. Summary of the invention

[0004] In order to solve the technical problems in the prior art, the present invention provides a visual monitoring data acquisition and analysis device, which can obtain an unprocessed image obtained by a data acquisition component for a certain shooting of a beach scene, perform preset image processing on the unprocessed image to obtain a corresponding representative processed image, the unprocessed image obtained by the data acquisition component for a certain shooting of the beach scene is a sensing image of a CCD sensor unit of the data acquisition component during a certain shooting before the data acquisition component outputs a scene captured image, obtain each gradient value corresponding to each pixel point of a foreground imaging area representing the processed image, and obtain each gradient value corresponding to each pixel point of a foreground imaging area representing the scene captured image. value, taking the arithmetic mean of each gradient value corresponding to each pixel point of the foreground imaging area of ​​the processed image as the first reference gradient value, taking the arithmetic mean of each gradient value corresponding to each pixel point of the foreground imaging area of ​​the scene captured image as the second reference gradient value, and when the difference obtained by subtracting the first reference gradient value from the second reference gradient value is less than the set gradient difference limit, it is identified that the scene captured image is obtained by the unprocessed image corresponding to the scene captured image through preset image processing in the data acquisition component, thereby utilizing the characteristic that the image content after the same image processing has the same image value regularity to complete the image source analysis of the scene captured image.

[0005] According to the present invention, a visual monitoring data collection and analysis device is provided, the device comprising: A data acquisition component, arranged at a beach location to perform capture of image data of the beach coverage area, for acquiring and outputting corresponding on-site captured images; A first acquisition component is connected to the data acquisition component and is used to obtain an unprocessed image obtained by the data acquisition component at a certain time of shooting the beach scene, and perform preset image processing on the unprocessed image to obtain a corresponding representative processed image, wherein the unprocessed image obtained by the data acquisition component at a certain time of shooting the beach scene is a sensing image of the CCD sensor unit of the data acquisition component at a certain time of shooting before the data acquisition component outputs the captured image on the scene; A second acquisition component, connected to the first acquisition component, for acquiring each gradient value corresponding to each pixel point of the foreground imaging area representing the processed image, and acquiring each gradient value corresponding to each pixel point of the foreground imaging area of ​​the live captured image; a signal identification mechanism connected to the second acquisition component, for taking the arithmetic mean of the gradient values ​​corresponding to the pixels of the foreground imaging area representing the processed image as the first reference gradient value, and taking the arithmetic mean of the gradient values ​​corresponding to the pixels of the foreground imaging area representing the scene captured image as the second reference gradient value, and when the difference obtained by subtracting the first reference gradient value from the second reference gradient value is less than a set gradient difference limit, identifying that the scene captured image is obtained by the unprocessed image corresponding to the scene captured image in the data acquisition component after the preset image processing, and issuing a first identification signal; otherwise, identifying that the scene captured image is not obtained by the unprocessed image corresponding to the scene captured image in the data acquisition component after the preset image processing, and issuing a second identification signal; A message notification mechanism, connected to the signal identification mechanism, for sending a notification message corresponding to the preset image processing of the on-site captured image in the data acquisition component to a remote cloud management node via a two-way communication link upon receiving the first identification signal; Wherein, the message notification mechanism is also used to send a notification message corresponding to the on-site captured image being an unprocessed image to a remote cloud management node through a two-way communication link when receiving the second identification signal.

[0006] It can be seen that the present invention has at least the following three significant substantive features: First, an unprocessed image obtained by a certain shooting of a beach scene by a data acquisition component is obtained, and a preset image processing is performed on the unprocessed image to obtain a corresponding representative processed image, wherein the unprocessed image obtained by a certain shooting of a beach scene by the data acquisition component is a sensing image of a CCD sensor unit of the data acquisition component during a certain shooting before the data acquisition component outputs a captured image on site; Second step: obtaining each gradient value corresponding to each pixel point of the foreground imaging area representing the processed image, and obtaining each gradient value corresponding to each pixel point of the foreground imaging area of ​​the live captured image; Thirdly, the arithmetic mean of the gradient values ​​corresponding to the pixels in the foreground imaging area of ​​the processed image is taken as the first reference gradient value, and the arithmetic mean of the gradient values ​​corresponding to the pixels in the foreground imaging area of ​​the scene-captured image is taken as the second reference gradient value. When the difference between the first reference gradient value and the second reference gradient value is less than the set gradient difference limit, the scene-captured image is identified as being obtained by the preset image processing of the raw image corresponding to the scene-captured image in the data acquisition component, thereby utilizing the characteristic that the image contents after the same image processing have the same image value regularity to complete the image source analysis of the scene-captured image.

[0007] The visual monitoring data acquisition and analysis device of the present invention is compact in design and has a certain level of intelligence. Since it can obtain the raw image obtained by a certain shooting of the beach scene by the data acquisition component, it can further identify whether the on-site captured image is obtained by the corresponding raw image through preset image processing, thereby completing the image source analysis of the on-site captured image.
