Image processing software eases car number plate reading

June 07, 2013 // By Julien Happich
EVT's EyePlateReader system, based on the company’s EyeVision image processing software, is designed to recognize, read and evaluate number plates. The system runs on a ARM Cortex A8 Dual Core CPU.

For this application the EyeBlock hardware is well suited for recognizing and reading number plates in moving traffic. Also for very fast applications an ARM A9 is recommendable. Whereas the base for this solution is the new OCR module, which even under very difficult conditions is recognizing the characters on the number plates. Due to the standardized modules, the EyeBlock hardware allows the user to select for each application the appropriate computer module.

The connection to the sensor module is also standardized and therefore all sensor modules are available for various computer modules. No matter if the camera module is located close to the processor, where the data can be transferred parallel or if the module is far away and the image data should be transferred serial, the appropriate module can be found easily. With the EyeVision software, all systems are graphically configured with a Qt-based user interface, easy to maintain and adjust to new applications. The software is completely programmable through a drag-and-drop function.
