Infrasense uses High Resolution Video Imagery to Map Surface Distress Conditions along 3-Miles of Road near Wichita, Kansas

Share Article

Infrasense, Inc., a national leader in infrastructure nondestructive evaluations, recently carried out traffic speed, vehicle mounted High-Resolution Video (HRV) Image survey along a three-mile stretch of road to document the pre-construction “baseline conditions” near Wichita, Kansas with no disruption to traffic flow. The results of the HRV image survey provided a detailed plan-view baseline conditions map of the three miles of road that outlined and quantified existing areas of distress prior to the roadways being used for access during a construction project.

Infrasense, Inc. was called in to collect high resolution video

A construction project near Wichita, Kansas involving the transportation of construction equipment and personnel between the state highway and a work site 3 miles down a two lane county road required a “baseline conditions” record to be produced. Infrasense, Inc. was called in to collect high resolution video to both record, and quantify the current road conditions, using the USDOT Distress Identification Manual as a guide.

The high resolution video imagery was captured using a vehicle mounted, 1080p resolution digital video camera, collecting at 30 fps with synchronous GPS coordinates. The HRV data was collected along a single continuous pass of each of the travel lanes. The Kansas project was comprised of two, adjacent two lane roads that connected the project site to a highway, requiring four traffic speed data collection passes with the camera. The combination of site specific calibration files and marks, and GPS data, allows for quick data collection without the need for lane closures, or disruptions to traffic flow.

The results of the survey consists of a digital video recording and a plan view map. The plan view map was created from the digital video using field calibration files and Infrasense’ proprietary HRV video processing software. The extracted image files are corrected for distortion, and pixel mapped prior to being digitally assembled, creating a single continuous image of the road. Infrasense engineers then analyzed and mapped out areas of distress along the road, quantifying the condition of the road in its current state.

The resulting digital video recording and plan view map were exactly what our client was looking for and will be used post-construction to identify new damage to the road following construction activities, including transportation of construction equipment and personnel.

Since 1987, Infrasense, Inc. has applied state-of-the-art technologies to address the most difficult challenges in subsurface scanning. Infrasense’ engineers are able to nondestructively extract critical information from a diverse range of structures. The firm has conducted research to advance the field of subsurface detection, while also providing valuable information to clients across the country.
