Embodiment Construction

[0021] The technical idea of ​​the present invention first obtains the pixel value of the oil spill area 1 quickly and accurately through the image processing technology, and then obtains the laser distance measuring machine reproduced on the basis of the high-precision two-dimensional servo structure, and measures the oil spill according to the edge conditions obtained by image processing The real distance between different positions of the oil film and the observation point, and the pixel value sum of the oil spill area is converted into the real area size2. Finally, the area calculation is performed by the corresponding area algorithm.

[0022] Specifically, the steps of the oil spill area estimation method based on image processing and laser ranging according to the present invention are as follows:

[0023] Step 1. Install the laser rangefinder and camera at the same horizontal position and height. During the installation process, adjust the optical axis of the initial po...

Abstract

The invention discloses a method for estimating oil spill area based on image processing and laser ranging, belonging to the field of marine environmental pollution detection and marine safety protection. At first, the pixel value of the oil spill area is quickly and accurately obtained by the image processing technology, then the laser rangefinder is reproduced on the basis of high-precision two-dimensional servo structure, according to the image processing obtained by the edge of the oil film to measure the different positions of the oil spill from the observation point of the true distance,the oil spill area of the pixel value and converted into the true size of the area. Then the area is calculated by the corresponding algorithm. The method disclosed by the invention ensures the estimation accuracy of the oil spill area, because the algorithm of image processing is relatively mature and easy to implement, and the cost of laser rangefinder is much lower than that of oil spill radar, the cost of oil spill area estimation is greatly reduced, which can provide a comparative basis for oil spill area estimation of ships equipped with oil spill radar, and effectively improve the efficiency of cleaning and recovering oil spill in the sea.

Description

technical field [0001] The invention belongs to the field of marine environmental pollution detection and marine safety protection, and in particular relates to a method for compositely estimating the oil spill area by image processing and laser ranging. Background technique [0002] As human ocean activities become more and more frequent and have a greater impact on the marine environment, people pay more and more attention to the pollution detection and marine safety protection of the marine environment. In marine environmental pollution incidents, the leakage of crude oil and other refined oil products is the most serious pollution situation, and the removal and recovery of spilled oil has always been the main means to solve such problems. In order to carry out oil spill removal and recovery more quickly and efficiently, it is very necessary and important to estimate the area and volume of oil spill. [0003] The traditional method of estimating the oil spill area is lim...
