Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with an embodiment of a computer vision-based water body monitoring method.
[0027] A computer vision-based water body monitoring method, including a computer vision-based drainage monitoring method, the method steps are as follows:
[0028] like figure 1 As shown, there are 2 drains in total, the left drain is draining, and the right drain is not draining. Now, the drainage status of the two drains is calculated through an algorithm based on computer vision. Before judging, first define the drainage state, first determine that there is water discharged from the drainage outlet, and secondly, the water flow direction is consistent with the preset direction. Because considering some specific scenarios, such as Image 6 In the case where the outlet is partially submerged as shown in the figure, it is possible to detect that there is water flow at the outlet, but it is not necessarily the out...

The invention discloses a drainage monitoring method based on computer vision and a water body monitoring method. The drainage monitoring method includes the following steps: firstly acquire a camera image, and divide the image into a rectangular area to be monitored drainBoxes and a preset water flow direction set flowLines , and record the coordinates of the drainBox of each area to be monitored in the set of areas to be monitored as [(x1, y1), (x2, y2)], where (x1, y1) and (x2, y2) are respectively on the drainBox of the area to be monitored Coordinates on the diagonal points; record the coordinates of each preset flow direction flowLine in the preset flow direction set flowLines as [(fx1, f y1), (fx2, fy2)], where (fx1, f y1) and ( fx2, fy2) are the coordinates of two points selected in sequence on the preset water flow direction flowLine. On the basis of the optical flow method, whether there is drainage is comprehensively judged according to whether there is water flow, the direction of water flow, and the proportion of water flow in the same direction. The invention has the advantages of being able to maintain continuous monitoring, preventing sneaky discharge, and reducing the input of manpower and material resources.
Description
technical field [0001] The invention relates to the technical field of hydrology and water conservancy monitoring, in particular to a computer vision-based drainage monitoring method and a water body monitoring method. Background technique [0002] In the water affairs, water conservancy, hydrology and other industries, it is necessary to monitor the drainage status, such as the supervision of the sewage discharge status of the sewage outlet of the factory. Whether it has crossed the dam, once the water flow has crossed the dam, a corresponding alarm will be generated); whether the water replenishment point is normally replenishing water, once the water replenishment state is abnormal, a corresponding alarm will be generated. Therefore, it is necessary to judge the water flow state in the monitoring or observation area. The existing drainage monitoring is mainly through manual inspection, camera monitoring or drone monitoring. These monitoring methods require a lot of manpo...
