  1. SeeLane LPR system

  2. SeeLane system • Overview • 2. Hardware • 3. Software Interface • 4. Triggering • 5. Installation • 6. Configuring

  3. SeeLane system (1) System Overview

  4. SeeLane system SCH3 unit Frame Grabber(s) PC Station Included Hardware I/O Card +Terminal Block Power Supply for SCH SeeLane Software + DLL+ Sample Client Program

  5. SeeLane System description • System includes camera/illumination units, hardware and software (application + recognition library) • Automatically reads License Plate number • Displays, records and transmits vehicle image and recognition results • Can compare plate number to data base - and optionally open gate or activate alarm

  6. SeeLane application - Window

  7. SeeLane -Highlights Handles single or multiple lanes- 1-6 lanes, each lane with different settings See/Lane can run in background & send DDE messages to your client application Easy configuration settings - communication, device interface, sensor types, capture and illumination modes. Password Controlled. Selectable illumination and image capture schemes - built-in intelligence and logic to handle different plate qualities Large display option for indoor or outdoor messages

  8. SeeLane system (2) Hardware

  9. SeeLane Configuration

  10. Frame Grabber • Inputs: 4 VIDEO inputs • One or more boards per PC • Compatible with standard PAL or NTSC cameras • Board is PCI bus mastering agents that directly store the acquired images into the PC physical memory without CPU involvement

  11. I/O Card Model: Advantech PCI 1751 + cable + TBL interface + cover box Inputs: sensors inputs Outputs: illumination control outputs, gate control

  12. SCH3 unit with illumination Camera/Illumination unit for access-control applications CCD 1/3” B&W CCIR varifocal lens up to 51 mm Weatherproof Case: IP 66 Die-Cast Aluminum Alloy, UV protected Internal illumination 3-Degrees freedom Mechanical interface

  13. SeeLane system (3) Software Interface

  14. System Build Options

  15. Interface - Serial • Serial output options: • Regular (vehicle code & authorized name) • Custom string (flexible formatted string, for parking systems or outdoor displays) • Serial communication could also be implemented in the Client application

  16. Interface - DDE The DDE message is generated on every vehicle. It contains vehicle #, date, lane, authorized flag, owner name, and optional image file pointer. User application can also initiate: “open gate” - forces a certain lane to open the gate “sensor” - simulates a sensor activation

  17. Networking DDE message is transmitted over the network by SeeData. The DDE is IDENTICAL as in local SeeLane - only lane # is different (set by SeeLane settings or in SeeData) Image can be transmitted - but the image’s path is better. The path can be local or absolute - according to SeeLane settings

  18. SeeLane system (4) Triggering

  19. Triggering (1) By external sensor (dry contact) - best is loop detector (2) By Client’s DDE message (3) Software trigger - “SeeRoad” system

  20. SeeLane system (5) Installing

  21. Front Plate Installation 0-0.5m Cam 1-15 m 7 m Trigger is when car steps on the loop

  22. Rear Plate Installation Cam 0-0.5m 6.5 m Triggering is when car leaves the loop

  23. Stereo 2 Sides Installation Cam 6.5 m 7 m Triggering is both when stepping ON and OFF* the loop

  24. SeeLane system (6) Configuring

  25. Format.ini - Recognition Configuration ;;Singapore [General] capture_width = 612 ; captured picture size capture_height = 264 ; frame = 1 ; whole frame = 1; even field = 0 deinterlace = 0 ; whether to deinterlace picture n_formats = 8 ; number of possible formats eliminate_separators = 1 [Locate] left_margin = 3 right_margin = 3 top_margin = 3 bottom_margin = 3 min_hor_plate_length = 60 max_hor_plate_length = 350 min_hor_plate_height = 15 max_hor_plate_height = 80 …... The file is used to configure the SeeCarDLL recognition library to specific applications, cameras and plate formats

  26. SeeLane Settings • There are 3 ways to get Application Settings: • Open Settings from the main menu • 2. Click on the settings icon in the tool bar • 3. Open Settings with hot key F8

  27. Lane settings Input - Sensor Pin Associates TBL (Terminal Block) pin to the lane’s sensor (loop detector). Range: 1 – max input pin number (1-8 for Advantech IO card) “Normally Open”: recognition starts when the input sensor (loop detector) goes from “open” to “close”. Used for front plate recognition installation. “Normally Closed”: recognition starts on transition from “close” to “open”. Used for rear plate recognition installation. Output - Gate Pin Associates TBL pin to the lane’s gate output

  28. Lane camera settings Video Input – Grabber Associates frame grabber board to the camera. Range: 0 – max number of installed frame grabber cards Video Input – Input Channel Associates frame grabber input pin to this camera. Range: 1 – 4 video inputs. Illumination – LSB Pin Associates TBL pin to the camera illumination control LSB . Capture on Sensor Defines the timing for start capturing images - in reference to the input sensor. “Rising” when the input goes to high; “Falling” when the input goes low.

  29. Lane camera settings – Capture Set Start time Defines the time of day to start this capture set. Not used in case of a single capture set. If another set is defined, the capture set will end at the start time of the next set. Illumination intensity Defines the illumination intensity for the current selected set item. Four levels can be selected: off, low, medium and high intensity. Number of captures Defines how many images to capture in the selected set item.

  30. General Settings Members Database – Search freedom Defines how to perform the match of the recognized plate to the member database. Larger numbers make less mistakes in recognizing authorized members, but could cause false-positive errors Client opens gate If set - the application will not open the gate, and waits for the Client application to send an approval for opening the gate. Smart Output If set – the application will not send out recognition results if there is no recognition.

  31. Images Images main directory Defines the local disk path where the images (or their sub-directories) are stored. User can use the browse button (“…”) to select the path from the existing disk directory, or type a new path. The application will create the directory is it does not yet exist . Output Share name If set – a network shared name can be defined in order to set the reported image path to a network drive. This is useful if the message containing the image path is transmitted over the network, so the remote node could access the image file name using the absolute path.

  32. Communication Networking. Center IP – IP address of SeeData Center Server . Data Port – communication port . Must be set the same port on SeeDataCenter Server .

  33. Lane Settings - Diagnostics The warning is recorded in the application Event log and will show as a “yellow” state in SeeMonitor. Note that when the recognition rate increases, the application will write an information event that cancels the warning
