Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0017] The present invention provides a method for identifying underwater sewage outlets based on underwater sonar, the embodiment of which is as follows figure 1 shown, including the following steps,
[0018] Step S1, using a sonar instrument to explore the underwater environment to obtain a sonar image;
[0019] Step S2, identifying the sonar image to find the sewage outlet;
[0020] Step S3, at the location where the sewage outlet is found, use the GPS tool to locate and determine the location information of the sewage outlet.
[0021] During the investigation work, the staff can reach the investigation area by hovercraft and other tools, and then use sonar instruments to explore the underwater environment. By interpreting the detection results of the sonar instruments, t...

The invention discloses a method for identifying an underwater dirt discharge opening based on underwater sonar. The method comprises the following steps: exploring an underwater environment through a sonar instrument, so as to obtain a sonar image; identifying the sonar image to find the dirt discharge opening; and after the position of the dirt discharge opening is found, positioning and determining the position information of the dirt discharge opening by using a GPS tool. After the scheme is adopted, a worker can know the underwater condition so as to judge whether the dirt discharge opening exists underwater or not and find the position of the dirt discharge opening, so that the troubleshooting difficulty of the underwater dirt discharge opening is greatly reduced, and the problem that the troubleshooting work of the existing dirt discharge opening is difficult is practically solved.
Description
technical field [0001] The invention relates to the technical field of sewage outlet recognition, in particular to a method for identifying underwater sewage outlets based on underwater sonar. Background technique [0002] In the existing technology, in order to conceal illegal sewage discharge, most factories often hide the sewage outlet underwater, or for other reasons, the sewage outlet is set up underwater at the beginning of the design, and even extends to the center of the river, so when When the staff conducts on-site inspections, it is often difficult to find out; or there are ebb and flow tides in some areas, so when the water level is high, the sewage outlets will be submerged, and there may even be mixed discharges, and foundation pit wastewater is secretly discharged along the rainwater pipes. Thereby bring great difficulty for the investigation work of blowdown outlet, be badly in need of a kind of technical scheme that can solve this problem for this reason. ...
