Method for transmitting spectrum information |
摘要 |
A method for transmitting spectrum information is provided. The method includes: sampling a first video of a scene by a first sampling device and sampling a spectrum video of a sampling point in the scene by a second sampling device, and processing the spectrum video to obtain a spectrum information of the sampling point; calculating estimated transmission ratio coefficients of the spectrum video according to color integral curves of the first sampling device; estimating a location of the sampling point in each frame of the first video; and transmitting the spectrum information of the sampling point to a plurality of scene points in the first video according to the estimated transmission ratio coefficients and the location of the sampling point in each frame of the spectrum video through a trilateral filtering algorithm. |

1. A method for transmitting spectrum information, comprising:
sampling a first video of a scene by a first sampling device and sampling a spectrum video of a sampling point in the scene by a second sampling device, and processing the spectrum video to obtain spectrum information of the sampling point; calculating estimated transmission ratio coefficients of the spectrum video according to color integral curves of the first sampling device; estimating a location of the sampling point in each frame of the first video; and transmitting the spectrum information of the sampling point to a plurality of scene points in the first video according to the estimated transmission ratio coefficients and the location of the sampling point in each frame of the spectrum video through a trilateral filtering algorithm. |
