hi everyone,

as I checked the VISP pakage (http://wiki.ros.org/visp), in one of its applications, it uses the QR code as a template for feature tracking. Is it possible that instead of QR code, any other image be used? for instance picture of a building??

Thanks

hi everyone,

in EKF-global and EKF-local related to the robot-localization package, there are two parameters: "process_noise_covariance" and "initial_estimate_covariance". how can i tune "process_noise_covariance" and "initial_estimate_covariance" for a 4wheel differential robot. the values on the diagonal are based on what? I would be grateful if someone explain to me these two parameters.

Thanks
