Recently, Texas Instruments (TI) announced that GeoVision Incorporated has adopted TI DaVinci technology to jointly develop license plate recognition technology and outdoor monitoring solutions. GeoVision's GV series products have adopted TI's TMS320DM6446 processor. GeoVision provides more comprehensive monitoring solutions to global customers by adding more value-added features to meet their needs for outdoor installation. The two companies are currently collaborating on DSP integrated monitoring solutions for license plate recognition and automatic license plate recognition (LPR/ANPR).

With TI's DaVinci technology, this non-PC-based GV-DSP LPR system does not require the installation of rotating equipment such as fans or hard drives. It can not only capture and realize high-quality video images, but also is not affected by changes in the outdoor environment. The GV-DSP LPR system achieves seamless integration through software and hardware support, forming the basis of the GV-LPR center that supports central control and database management. GeoVision's LPR system also uses TI analog technology, including the TPS5420 DC/DC converter, TPS3808G09 power management device and OPA357 operational amplifier, to build a complete and efficient signal chain solution.

By combining TI's Da Vinci products with GeoVision's LPR technology, GeoVision and TI hope to significantly promote the development of the LPR/ANPR market. GeoVision's LPR system is not only low-cost to install, but also scalable. The equipment can be widely deployed to bring customers a higher return on investment, so as to better meet the needs of intelligent transportation systems.

The GV-DSP LPR system is currently used in transportation, law enforcement, remote control and taxation. The more comprehensive system will help customers significantly improve the performance of monitoring systems and simplify the application process. The latest GV-DSP LPR system will benefit applications that require continuous monitoring of large numbers of vehicles, such as parking management, access control, automatic toll collection, traffic enforcement data, border monitoring, stolen vehicle searches, congestion charges, inventory control, travel time/average speed calculations, and even petrol station drive-off prevention. The GV-DSP LPR system also integrates a variety of intelligent value-added features, such as a web-based interface for setup, real-time viewing, firmware upgrades, video search and analysis tools for market analysis, hardware watchdog to detect hardware anomalies, and digital watermarking to prevent recorded video images from being tampered with or destroyed.

TI is very pleased that GeoVision has selected TI DaVinci technology and analog technology for its LPR system products, and sees the LPR market as a key emerging market in the field of video security. TI's innovative DaVinci technology combined with GeoVision's expertise in the LPR market will further accelerate the development of new video surveillance applications and services and simplify development work."
