Lösungen gegenüber gestellt werden.
“Calibrated” images are usually reddish, attributed to atmospheric dust, but hues range widely because of the great uncertainty in the illumination spectrum. Solar black body radiation, the same on Mars as on Earth, is minimally modified by the atmosphere of either planet. For red dust to change the spectrum significantly, reflected light must exceed the transmitted light. Were this the case, shadows would be virtually eliminated. Viking images show prominent shadows. Also, Pathfinder’s solar cells, activated by blue light, would have failed under the predominately red spectrum generally attributed to Mars.
Accordingly, no consensus has emerged on the colors of the soil, rocks and sky of Mars. This paper proposes two techniques to eliminate color uncertainty from future images, and also to allow recalibration of past images: 1. Calibration of cameras at night through minimal atmospheric paths using light sources brought from Earth, which, used during the day, would permit calculation of red, green and blue intensities independent of scene illumination; 2. Use of hyperspectral imaging to measure the complete spectrum of each pixel.
This paper includes a calibration of a NASA Viking lander image based on its color chart as it appears on Earth. The more realistic Martian colors become far more interesting, showing blue skies, brownish soil and rocks, both with yellow, olive, and greenish areas.
Problem: Falsche Farbe Lösung:Kalibrieren
Problem: Zu viel Rot Lösung:Farbkanäle reduzieren, ausgleichen
Das das Legitim ist sagt die NASA doch selber:
Das sind Wissenschaftliche Aufnahmen, es wurden so viel
Daten wie möglich übertragen, alle Filter auch Infrarot und
Ultraviolet, die nennen das TrueColor. Bilder die an unser
Auge angepasst sind nennen Sie FalseColor, das ist etwas
irreführend steck aber keine böse absicht dahinter.
