Sumitomo 3M Limited : Retro-reflective Color Code System
【What is retro-Reflective Color Code system (RCC)?】
Retro-reflective color code system (abbr. RCC) is a system to apply Color Bit Code to sumitomo 3M's retro-reflective technology.
【What is retro-reflectivity?】

Left: Retro-reflectivity example
Right: Work uniforms using retro-reflective fabric
Retro-reflectivity : Light is reflected and returns to its own direction.
Retro-reflective products are one of their core technologies.
[Examples of retro-reflective products]
Left:"Retro-reflective sheet" used for traffic sign etc.
Right:"Retro-reflective fabric " used for construction worker's uniform etc.
【RCC technology】

RCC=Color Bit Code+3M's retro-reflective sheet
- Color Bit Code is printed on a retro-reflective sheet., becoming a code tag.
- The code can be decoded because the light reflects off the code tag and returns to its own direction.
- Decoder consists of camera and floodlight.
- The decoder captures color infomation of the code with the reflected light by shooting and floodlighting the code.
【Advantages of RCC】
- Main advantage : RCC can be decoded even in a dark and from a distance.
- RCC can be decoded from 100m of distance as long as the light reaches.
- RCC has more superior advantages than RFID because the position of RCC tag can be detected and the detection is unaffected by metals.
【Possible applications of RCC】

- Object search in the dark
- Object search from a distance
- Identification of moving object
- Simultaneous identification of multiple objects
