1 Tlhaloso ea tšebetso
1.1 Sisteme e felileview
Sistimi ea VL53L5CX e entsoe ka module ea hardware le software ea ULD (VL53L5CX ULD) e sebetsang ho moamoheli (bona setšoantšo se ka tlase). Mojule oa Hardware o na le sensor ea Nako ea Sefofane (ToF). ST e fana ka mokhanni oa software eo ho buuoang ka eena tokomaneng ena e le "mokhanni". Tokomane ena e hlalosa mesebetsi ea mokhanni e fumanehang ho moamoheli. Mesebetsi ena e laola sensor mme e fumana data e fapaneng.
