With the vehicle’s combination of exterior lasers, cameras and GPS equipment, we get some strange looks, double-takes and innumerable questions from passers-by whenever our MAC vehicles are on the road.
The "MAC" (Mobile Asset Collection) vehicle is outfitted with state-of-the-art data collection instruments. The combination of digital cameras, ground-based LiDAR, Inertial Measuring Units (IMU), Global Positioning System (GPS) technology, and data collection software enables us to efficiently collect above-ground roadway infrastructure and deliver it in an efficient manner. The MAC vehicle collects georeferenced information related to above-ground roadway data.
How it Works
Using two high-resolution video cameras, a laser scanner, and GPS technology, the vehicle calculates the geographic location of any above-ground asset with high spatial accuracy.
The two Sony SX-910 cameras produce images at a rate of 7.5 frames per second, which allows the vehicle to drive at posted speed limits while gathering data.
The ground-based LiDAR allows for automatic feature detection (signs, light poles, markings) and can also be used to generate a 3D model of the right-of-way.
The DMI (Distance Measuring Instrument) and IMU enable centimeter-level positioning of the vehicle at all times.
The on-board GPS equipment provides positional tagging of the images gathered, as well as precise positioning of the vehicle.
Examples of assets we collect:
- Signs
- Signals
- Intersections
- Sidewalks
- Curb & Gutter
- Drainage Inlets
- E911 Addresses
- Manholes
- Lighting
- Trees
- Utility Poles
- Pavement Condition
