Achieving a 98.5 percent gate OCR accuracy at Peru's DP World terminal
In operation since 2018, the Camco OCR Truck-In portal keeps exception jobs to a minimum.
DP World Callao, Peru's first container terminal
DP World Callao is the largest and most automated container terminal in Peru. It is also South America’s fifth-largest container terminal. The terminal is located in a densely populated area on the outskirts of Lima.
The Callao DP World Terminal’s throughput in 2020 was just over 1.350.000 TEU. Today, 7 STS cranes can load and unload neo-Panamax container vessels. To meet increasing capacity, DP World Callao is investing in the expansion of its pier. An additional 300 meters will be added to the current 650 meters of berthing space and with 2 additional STS cranes, the DP World Callao terminal will be able to simultaneously handle up to three neo-Panamax vessels.
Vehicle Booking System
The terminal main access road is also used by Callao’s commuting inhabitants with limited space available to manage the increasing container truck flow. With a bulk cargo terminal located at the adjacent plot, traffic is dense 24/7.
The DP World Callao gate processes up to 2500 trucks per day. To flatten out peaks and avoid traffic jams or blocking the Jr Manco Avenue, DP World Callao implemented a truck appointment system.
Trucks have to register for a timeslot. Early or incomplete appointments aren’t allowed, trucks have to turn around and book a new appointment. Regular communication between the terminal and the trucking companies contributes to the success of the Vehicle Booking System implementation.
Gate security checks
With truck appointment data available upfront, less time is needed for the gate access process. Trucks drive through a series of Camco Technologies AI-camera systems and are requested to stop for a manual cabin check by terminal clerks.
For security reasons, the cabin is checked for hiding and unauthorized intruders. At the same time, terminal clerks collect the driver’s biometric data.
Finetuning the OCR performance and kiosk registration process
Since its installation in 2018, the Camco OCR video gate hit-rate has been improving gradually. Technicians optimized camera positions and adjusted the lenses focus: in Peru, trucks can have their front license plate almost anywhere. Software updates were implemented as well.
Trucks were no longer allowed to use the OOG lane and the kiosks registration process was cut short by leaving out the weighing system, reducing manual data checks and significantly improving truck processing time.
The most significant improvement in the OCR hit-rate is obtained by matching the pre-registration VBS data to the Camco camera system. Missing or difficult-to-read data are automatically checked with the upfront available information, increasing the overall OCR accuracy up to 98.5 percent!
