extended remote viewing
How you meet the demands of your remote visual inspection challenges -- from push cameras to pipe crawlers -- will depend on the diameter, inclination, access and angle you have available to you.
Whether you’re looking for a simple forward-view camera, pan and tilt inspection camera with continuous rotation, inclination reporting, point-to-point measurement, sonde locating, laser profiling, or 3D optical scanning for 360° and unfolded views,
The right inspection systems vendor can help you find the right tool to suit your needs offering pipeline inspection equipment made by such OEMs as Ibak, InsightVision, Pearpoint, Inuktun and other leading OEMS all backed by our advanced service support by skilled inspection technicians.
Pipe inspection accessories include pipe locators and sondes, roller skid centering devices, foreign object search and retrieval tools, rigidizers, magic arms, light sources, cooling sleeves, extended life battery packs and equipment cases. A world of RVI resources is your world of solutions.
Panoramo SI has so far proven to be the most cost-effective and fastest method of inspecting large numbers of manholes, and produces a level of data superior to any other alternative currently available. The process for using Panoramo SI to inspect a manhole involves the operator remotely lowering the device to the bottom of the manhole, and then retracting the cable. Panoramo SI conducts its scan of the interior of the manhole on the way up, snapping images from the top and bottom camera every 2 in. on its way up the manhole at a speed of 14 in. per second. The operator will then save the data and move on to the next manhole. This technology is intended for analysis and reporting to be carried out later, in an office-setting, enabling the field technician to specialize and become only a data collector and equipment operator. The data is then turned over to a specialist in an office to complete the analysis and report at his or her leisure.
Since Panoramo SI produces a 360 field of view from anywhere inside the manhole, and an unfolded view of the entire surface of the manhole, nothing is missed. Human error on the part of the field operator can be eliminated to a far greater degree than any other method available. Also, the unfolded view allows for a significantly greater amount of detail at 3,000 horizontal lines of resolution, compared to about 470 lines for most high-end CCTV cameras.
Perhaps the most valuable feature related to Panoramo SI, however, is its ability to produce geometric data on the manhole in the form of a 3D scatter plot profile. The down-hole facing camera, as it takes pictures every 2 in. on its way up the manhole, is photographing the stationary objects in the manhole as it moves away from them. The IBAK Panoramo software is able to account for the amount of contrast variance on the pixels representing the stationary objects as the camera is moving away from these objects. By comparing the change in contrast to the position of the camera, the position of the object can be triangulated and this data is represented in the form of a dot in a 3-dimensional space. The scatter plot consists of thousands of these dots. 3D measurement is possible in the profile, as well as analysis of the ovality of the manhole, as the Panoramo software enables measurement of circumference (or perimeter for square manholes). With this data on manhole ovality, the user is able to detect if the barrel of the manhole is buckling or if collapse is imminent, a level of analysis not possible with strictly visual methods of manhole inspection.
