A vision-based detection system and method for the docking status of an unmanned water harvesting device

Abstract

The invention relates to a system and method for detecting the butting state of an unmanned surface vehicle water collecting device based on vision, and discloses a system and method applied to an unmanned water quality detection vehicle to perform real-time detection on the butting state of a water collecting device. The detection system comprises a video collection module, a wireless image transmission module and a terminal processing and display module. The detection method comprises the steps that the video collection module collects an image, the wireless image transmission module transmits the image to the terminal processing and display module, and the terminal processing and display module receives the image and then operates a region-of-interest threshold detection algorithm to process and display the image and finally acquires a result on whether the butt-joint is successful or not. The system disclosed by the invention is easy to set up and operate and low in cost, realizesautomatic detection for the butting state of a water collecting device butting mechanism on the unmanned water quality detection vehicle, improves the automation degree of the unmanned water quality detection vehicle, and is more intelligent and efficient.

Description

Technical field [0001] The invention relates to the technical field of unmanned equipment, in particular to an unmanned water quality inspection boat, in particular to a system and method for real-time detection of the docking state of a water collection device applied on an unmanned water quality inspection boat. Background technique [0002] At present, my country's marine water quality testing mainly relies on manual collection and testing. The testing cost is high, the automation cost is low, and the risk of going to sea is high. At the same time, some sea areas are not suitable for human operations due to pollution and high risk. With the increasing maturity of unmanned boat technology and the development and application of automatic water quality inspection equipment, unmanned water quality inspection boats have emerged, which can realize automatic collection, distribution and detection of water samples. However, CTD (thermometer and salt depth) is connected to it. 1) Wheth...

Problems solved by technology

[0003] Since the unmanned water quality inspection boat is in an unmanned autonomous process when performing water quality inspection tasks, people can only monitor remotely on the mother ship or shore base. Simple video monitoring requires a lot of time and energy for the monitor, and in certain environments From The picture effect under the monitoring screen is not good, which will bring inconvenience or even mistakes to manual monitoring. This not only causes a waste of human resources, but also may cause errors in monitoring results. Therefore, an automatic detection system is needed for docking Institutions monitor in real time
