Abstract:

CE-1 carries two types of mapping equipments: CE-1 Lunar laser altimeter and three-line-array stereo camera. Laser altimeter collects accurate laser altimetry data over the Lunar surface, while stereo camera acquires high resolution three-line-array CCD images. By means of an inconsistency analysis of stereo image and laser altimeter data, the CE-1 Laser altimeter ranges are expected to be incorporated into the bundle adjustment as measurements to improve accuracy of CE-1 image photogrammetric reduction. An improved exterior orientation model is proposed in which exterior orientation line element interpolation model is established with the 3 order Lagrange polynomial and the attitude interpolation model is established using spherical linear interpolation of quaternion. Secondly, a bundle combined adjustment of CE-1 stereo camera image and laser altimeter data is developed and implemented in this paper. experiment results show that the bundle combined adjustment model is effective.

Key words: CE-1 three-line-array CCD sensor, laser altimeter, combined adjustment, scale control constraints
