The research on the reconstruction of intensity image based on streak tube imaging lidar

In the system based on the streak tube imaging lidar (STIL), the streak image on the salt screen captured by the CCD camera not only includes the range information, but also provides the material attribute, the angle information of the target and so on, that is the intensity information. It is generally assumed that the image brightness on the salt screen reflect the laser intensity of the target. However, the brightness not only relates to the density of the electron beam, but also relates to the accelerating voltage. The relative intensity of the streak image will be distorted for reasons of the different accelerating voltage resulted by the different coming time. An amended method that there is a weighted processing for the intensity information based on the range information was proposed, a research on the reconstruction of the intensity image was processed, and some effects were achieved.
