Super Resolution for Active Light Sensor Enhancement
This thesis provides a new approach for enhancing disparity detection of
color-depth-sensors (RGB-D-sensors). The infrared images captured by an
RGB-D-sensor are evaluated to detect subtle di erences in the light path
of the sensor's laser projection and these di erences are exported as o set
vectors.
An algorithm is introduced, implemented, and tested, that is able to
detect and quantify the light path's di erences. Furthermore, an approach
to obtain a reference brightness distribution of an average spot of the RGBD-
sensor's projector is presented. The reference brightness distribution is
used to identify spot positions with sub-pixel accuracy in infrared images
captured with the RGB-D-sensor.
The system is employed to detect refractive media, being introduced
to the captured scene. It is shown that the presence of refractive media
introduced to a scene can be detected.
