USB PC Camera

Existing technologies such as infrared imaging camera can help penetrate a certain concentration of fog or smoke, but the mainland this fog and haze is another matter. Haze particles quantity, density, light -blocking effect for almost a brick wall pretty . Kongzai Long said: " Based on our experience , when USB PC Camera visibility is reduced to 3 meters or less, even the best camera, monitoring distance can only reach over 10 meters ."

The central government has realized the seriousness of haze and appoint researchers to find solutions. Funded by National Natural Science Foundation of China to support two research teams ( one from local , one from the military ) research haze problem and require the relevant researchers in the four years to find a solution .

Local research team leader, Electronic and Information Engineering , Tianjin University digital imaging technology expert Yang Aiping said, because there is a huge technical challenge , she faces the pressure is very great.

Yang Aiping said: "The study of other countries mainly on fog in China , most people think , deal with fog and haze can be used the same way . Our preliminary results show that the optical properties of haze and mist particles of water molecules herein. some mathematical model algorithm, if not completely overturned , it must be substantially modified . Additionally, you must be a lot of computer simulation and large-scale field tests . "

Researchers need to have innovative thinking . He said : "In the fog and haze days, we may need to use radar to protect http://www.pandawill.com/computer-laptops-c175/webcam-c177.html some sensitive regional security ."

Reported that the microwave or electromagnetic waves can easily pass through the haze , an obstacle will retrace. If accompanied by good software , you can generate a clear image. But radar camera will produce radiation, harmful to human health. Zhang Li said: "This is only one kind of emergency equipment .
