Taylors are early adopters of technology and have been for many years. When GPS became available in the early 1990’s, Taylors were quick to embrace the technology and incorporate GPS in to our standard service offering. Similarly, when robotic total stations became available, Taylors jumped at the chance to make our field parties more efficient and cost effective. In more recent times Taylors have used vehicle mounted LIDAR technology to deliver surveying services.

What is Vehicle Borne LIDAR?

A mobile solution using LIDAR, whilst not a widely available technology, provides extremely fast survey results for large-scale projects. LIDAR uses ultraviolet, visible, or near infrared light to image objects and can be used with a wide range of targets. A laser beam is used to map physical features with very high resolution. Our vehicle mounted LIDAR solution overcomes the challenges of mapping linear features to a high level of accuracy. Accurate vehicle positions are obtained using three redundant technologies: a dual frequency GNSS receiver establishes a geospatial position; an Inertial Measurement Unit (IMU) tracks vehicle position; and connection to the vehicle CAN bus or external wheel encoders obtains odometry information. These three technologies work together to sustain a highly accurate 3D position for the vehicle even in locations where satellite signals can be blocked by obstructions such as buildings, bridges, or tree lines.

Added benefits of Vehicle Borne LIDAR – High Resolution Imagery

An important component of the IP-S2 mobile mapping system is its capture of high resolution 360 degree imagery, while acquiring 3D survey points, the system also logs imagery at user nominated intervals, to create geo-referenced images or video logs. This can become an important historical record of current conditions and as constructed activities. It also further enhances the design engineer’s ability to review field conditions and clarify issues from their desk top without un-necessary time loss and costly revisits to site.
