Jitter investigation in time-of-flight range imaging cameras
Abstract: The time-of-flight (ToF) range imaging cameras indirectly measure the time taken from the modulation light source to the scene and back to the camera and it is this principle that is used in range imaging to perform depth measurements. Commercially available ToF cameras have low resolution and relatively high noise level due to electronic source and timing jitter. The purpose of this research is to investigate the effect of jitter on range measurement in ToF range imaging cameras.
