Photometric visual servoing
WebMar 31, 2024 · * See the file LICENSE.txt at the root directory of this source Webmetric visual servoing4 is mainly based on the simple extraction of the image gradient, consequently removing any other necessity for image processing. The main draw-backs of photometric visual servoing are the strong non-linearities in the system dynamics: to address this problem, the use of photometric moments has been introduced.

It concerns the use of shearlet coefficients in case of ultrasounds (US) images as visual signal inputs and the design of the associated interaction matrix. The proposed controller was validated in both simulation and on an experimental test bench …
WebMay 10, 2024 · To date, most of visual servoing approaches have relied on the geometric features that have to be tracked and matched in the image. Recent works have highlighted the importance of taking into account the photometric information of the entire images. This leads to direct visual servoing (DVS) approaches. The main disadvantage of DVS is its … WebOpen Source Visual Servoing Platform. Contribute to lagadic/visp development by creating an account on GitHub.
