State-of the-art traffic camera systems have evolved from a simple monitoring or capturing device, into a highly-integrated, feature-rich part of a complete system.
Known by multiple names,
Automatic Number Plate Recognition (ANPR), or
Intelligent Traffic System (ITS), this surveillance method uses optical character recognition to read vehicle specifics.
We are all aware of red-light cameras … you know, those cameras that capture your license plate number (and sometimes picture) when you roll through that red light you could swear was yellow when you went through it. Well, this is an example of an Intelligent Traffic System, i.e., a camera that uses it’s ‘eye’ to record that split-second high-quality photograph needed to show you the error of your ways. This ITS system now makes way for
LPR (license plate recognition), a precise process of data gathering, where movement and high speed variables can be captured as still images or video feeds in real time. No question as to when one went through the red light.
Basler Industrial Cameras has revealed a camera that produces top-quality images specifically for fast moving objects. The
BIP2-1600-25c-dn IP camera produces uncompressed images (YUV feature) in extraordinary detail. These uncompressed images are then sent directly to a PC – with this, no image information is lost in the compression process. License Plate Recognition algorithms are produced with considerably better outcome than for compressed images such as JPEG or even H.264.
Utilizing its
slow shutter speed of 25 frames per second (short exposure time avoids motion blur for high speed application and flash synchronization), the Basler BIP2-1600-25c-dn
is this License
Plate Recognition camera. A high resolution progressive scan camera with an exceedingly sensitive 2MP sensor, has day/night removable
Infra-Red Cut Filter, and can detect, recognize and search license plates, and then record to match a data base’s stored license plate numbers.
Utilizing a real-time trigger function with an uncompressed YUV output format for detail-rich images in license plate recognition, this network camera has a maximum frame rate of 25 fps in MJPEG, MPEG-4 and H.264 formats. Able to operate in a wide range of light conditions, color: 0.4 lux (F1.4/33ms), day/night: 0.11 lux (F1.4/33ms), it has automatic and manual exposure control, and progressive scan
CCD image sensor. With image controls of automatic gain, backlight compensation, white balance, 180° image rotation, privacy masking and motion detection, it has the ability for independent stream processing (e.g. single car/overview of a scene), and operates in a wide range of light conditions.
This fixed box camera resides in a metal housing that is 109.7mm x 44mm x 29mm (4.32inch x 1.73inch x 1.14inch), metal, and weighs 210 g (less than 7.41 ounces). This High Definition (HD) camera with its ring buffer alarm buffer, has pre and post images; events that are triggered by motion detection or a real-time trigger, can then uploaded over FTP, email or HTTP.
With an eye fixed directly on the future
, Basler’s BIP2-1600-25c-dn camera is the ultimate choice for all types of license plate detection and other traffic camera applications.
