Abstract
The invention belongs to the field of ocean ecological environment monitoring, and relates to a novel method for monitoring oil spill change of a beach by using a computer image. A thick layer of crude oil is covered on a rock in a mudflat seacoast wetland polluted by petroleum, and the change condition (the relative brightness value is the ratio of the brightness value of the rock covered by the crude oil to the brightness value of the rock which is not covered by the crude oil) of the crude oil is reflected by monitoring the relative brightness value of greasy dirt. The higher the relative brightness value is, the less the crude oil residue in the seacoast wetland is, and the better the remediation effect is. The novel method has the beneficial effects of being time-saving, simple and convenient to operate, and the like, and can be applied to real-time observation of the seacoast wetland polluted by the petroleum.
Description
Technical field
The invention belongs to marine eco-environment monitoring field.Relate to a kind of novel computer image seabeach oil spilling variation monitoring method.
Background technology
Petroleum pollution in ocean refers to that the mankind bring oil into ocean by processes such as oil exploitation processing, discharge of wastewater, maritime traffic transportations, cause affecting extra large gas exchange, reduce primary productivity of marine ecosystem, harm biological existence, the ecological deterioration phenomenons such as the view of destruction seashore wetland and scenic spot.
Along with the fast development of Active Eyes, monitoring remote video has become a kind of important ECOLOGICAL ENVIRONMENTAL MONITORING means, but application is also less aspect the oil spilling variation monitoring of seabeach, this method will be take monitoring remote video as instrument, computer image processing techniques, set up one in real time, seabeach oil spilling variation monitoring method fast.
Install after 3G video monitoring system in oil spilling district, seabeach, the long-term image monitoring in environmental pollution region, the relative brightness value of monitoring greasy dirt reflects the situation of change of crude oil.Just can understand at any time the situation at oil pollution scene by Computer Image Processing, the recovery of seashore wetland is carried out to analysis and evaluation.Determine that pollutant exerts an influence to environment and the timing node of self-cleaning.
Summary of the invention
The scheme that the present invention solves its technical matters is:
1. utilize 3G video monitoring system to capture oil spilling district, seabeach monitoring image;
2. extract the brightness value of monitoring image Crude Oil overlying rock and the rock brightness value that does not have crude oil to cover;
3. calculate relative brightness value, the rock brightness value of the brightness value of relative brightness value=crude oil overlying rock/do not have crude oil to cover.
The present invention ground beneficial effect is, this monitoring new method is both time saving and energy saving, again Environmental Safety, also save monitoring expense, be suitable for applying in China, be ecological environmental protection and the service of building.
Accompanying drawing explanation
Fig. 1 is the relation of time and relative brightness value.
In figure, take relative brightness value as ordinate, take the time as horizontal ordinate.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details:
As shown in Figure 1, choose monitoring image effective in 132 days, adopt ENVI software to extract the brightness value of monitoring image Crude Oil overlying rock and the rock brightness value that does not have crude oil to cover, calculate relative brightness value, the results are shown in Table 1 and Fig. 1.From table 1 and Fig. 1, in whole monitoring time, relative brightness value Changing Pattern is followed function y=1.6381ln(t)+83.98(wherein t represent the time, y represents relative brightness value), the time is longer, and relative brightness value is higher, crude oil residual quantity is fewer, and recovery effects is better.
