I am currently involved in a project using the R200 camera which enables visually impaired people to navigate by avoiding obstacles. I just wanted to understand which feature to use for this purpose or if there is any other easy inbuilt method to perform this activity? If not, Is blob detection the way to go? (By identifying the amount of black to white ratios from the stream) or is there a better way to perform this activity? A method maybe to find the distance to the closest object/obstacle acquired by the camera video stream?
Please let me know.
Thank you for your patience. We've been investigating about obstacle avoidance options on the R200. Obstacle avoidance algorithms are a feature that has not been developed for the R200. The ZR300 Dev Kit with the RealSense SDK for Linux is best suited for this type of use case.
