What is Opto-chrono Code?
Concept
Device sample of Opto-chrono Code using 3 color LED
This technology uses color transition of light emitted same as Color Bit Code. The difference of them is that Opto-chrono Code is detecting the color transition in time wise while Color Bit Code is detecting the color transition in 2-dimensional area. After detecting the color transition, they are decoded in similar manner. The detecting point is the pin-point and it can be detected with their positions and ID. Further it can be tracked simultaneously.
※Here is Opto-chrono Code demo video. In this video, you can see that multiple Opto-chrono codes which are mounted on toy cars are being decoded simultaneously even if the cars are quickly moving. You can see ID numbers of each code are displayed on the moniter while being decoded.
Theory
Main Features
- ID and its position detectable at the same time
- Quick moving objects can be tracked.
- Multiple moving objects can be tracked simultaneously.
- Detectable under conditions of light/color noise in background
- Detectable even with blurry image
- Distance does not matter. (Detectable irrespective of distance)
- Detectable with off-the-shelf digital movie camera and PC
- Codes are changeable on demand which can be used as a part
of communication.
