DETERMINING CHARACTERISTICS OF LIQUID-CONTAINING VESSELS SUCH AS SWIMMING POOLS AND SPAS AND USING SUCH CHARACTERISTICS IN OPERATION OF THE VESSELS

摘要

Augmented (virtual) reality techniques are described for assisting in determining characteristics of swimming pools and spas. Such pools and spas may, for example, be mapped at least as to their general sizes and shapes. The mapped and other information may be available for display and may be furnished to an automatic swimming pool cleaner (APC) to improve its operational efficiency in cleaning the pool.
