Mandli introduces INO's new Laser Road Imaging System (LRIS) that
collects high-resolution pavement images from a vehicle traveling
at highway speeds using a dual line-scan camera system. An artificial
lighting unit eliminates the affects of shadowing and changes in the
ambient light level. The images collected can help to provide a distress
analysis that is consistent with the rating specified in the SHARPS manual
or can be customized to fit other rating systems. The INO LRIS is integrated
along with all of Mandli's data collection systems.
Features
- 4-meter wide continuous coverage of the pavement
- Consistent pavement lighting
- Data collection accurate at highway speeds
- Accurate, repeatable results
- Non-obtrusive system contained within width of vehicle
- Software with robust graphical user-interface
Major System Components
Dual Line-Scan Cameras
Digital line-scan cameras are mounted to each side
of the rear of the data collection vehicle, providing
a 4 meter wide area of continuous coverage.
Pavement Lighting Unit
An artificial light source illuminates the surface of the pavement to
provide consistent lighting that ensures quality images are collected with the camera system.
Distance Measurement Instrument
The system incorporates a high-resolution DMI which is used to ensure continuous pavement
images regardless of the speed of travel during data collection. The DMI provides a measure
of the vehicle's linear distance travelled and is able to measure distances accurate to
within +/- one-thousandth (0.001) mile per mile.
Mandli Image Compression System (MICS)
The MICS captures and compresses data in real-time, ensuring uninterrupted quality data
at all highway speeds.
System Controller and LCD Monitor
Data collection is controlled by a rack-mounted CPU with necessary processing
speed, storage, and software to collect data in a real-time environment.
The LCD monitor is located in the front of the vehicle and secured with an
ergonomically placed shock-absorbing mount featuring a spring-loaded
rubber-coated hold-down with side locks.
Analysis Workstation
The downward imaging system includes an analysis workstation fully-loaded with current
operating system software and Mandli's customized software for working with downward
images. The combination of the high-resolution digital imaging and DMI information
can be used to generate a distress report for a particular roadway. Roadview
Distress Player offers the option to view images in succession and visually
rate each one for quality control purposes. Multiple users can then use a
network based application provided by Mandli to view the data synchronously or
query it in an asynchronous manner.
Output
Each pass of the imaging system collects a 4096 pixel JPEG image. Single line-scans
are combined to produce images with a user-selectable length. When integrated with
right-of-way images, the downward images are always set to a corresponding interval
segment for easy analysis.
Downward images can be loaded into Mandli's Pavement Analyis and Distress software.
Alternately, pavement condition data can be formatted for use with existing pavement
management software such as MicroPaverŽ.

Purchase Options
Customized systems can be built for purchase, or data can be delivered as part of a service package.
