New method uses rolling-shutter camera distortions to estimate object velocity

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new method to estimate the 3D velocity of spherical objects by analyzing the distortions caused by rolling-shutter cameras. Instead of treating these distortions as artifacts, the technique leverages them as a source of temporal information. The method uses a specially designed spherical pattern and a correspondence-free formulation to recover motion through geometric consistency, enabling accurate velocity recovery even for textureless objects under high-speed conditions.
