Realtime Traffic Sign Recognition (TSR)
Realtime application
The CSC-TSR, a fast, robust color image evaluation system for the detection of traffic signs on European highways, is installed in a driving car (Figure 1). The realtime ability is achieved with parallel implementation on a TIP-system (Parsytec Transputer Image Processing) with PowerPC processors (Motorola MPC).

(Figure 1: CSC-TSR within a car)
- Image recording with a 3-chip CCD camera (Teli, Sony)
- Image digitizing with the TIP-CFG (Color Frame Grabber)
- CSC-VZE with TIP-MPC (Motorola PowerPC 601)
- Results transferred to the TIP-CGD (Color Graphics Display)
- Display of the results on a notebook (Sparc PowerLite)
TIP-System
- parallel architecture developed by Parsytec
- special BUS-system for online image-transfer
- special processing nodes for graphical in-/output
- Color Frame Grabber (CFG), Color Graphics Display (CGD)
- processing nodes with T805-Transputer (VPU)
- integration of MPC processing nodes with Motorola PowerPC 601 processor (MPC)
- integration of Texas-Instruments C40 processing nodes

Cooperation
The CSC-TSR has been developed in cooperation with Daimler Benz within the European PROMETHEUS project (Programme for a European Traffic with Highest Efficiency and Unprecedented Safety).
It has been integrated into the autonomous car VITA II.
Performance
- Database of approx. 40.000 traffic scenes
- Analysis of 3 images per second
- Recognition rate of 98 %
