| Zusammenfassung: | The invention relates to a visible light earth radiance simulator used for star-sensor ground experiment. The visible light earth radiance simulator comprises a fixing support and a luminescence surface arranged on the fixing support; the luminescence surface is spliced by several luminescence units along longitude and latitude direction; the spliced luminescence surface is a 1/4 inner ball surface with spherical surface radius being R. The visible light earth radiance simulator provides backlight for star-sensor ground experiment, can increase the validity and credibility of the star-sensor ground experiment, and the invention also provides an image transformation method. |
