Vehicle-borne mobile measurement integrates inertial guidance system, LIDAR, and visible light camera, which can acquire visible light images and high-precision laser point cloud data of road surface and both sides of the road at the same time. We can compensate for the lack of street view data caused by aerial photography with an obscured view at high altitude. We acquire data with high speed, high precision and large amount of information, which can be used for comprehensive road inspection, navigation data acquisition and DLG rapid update. It can be widely used in the fields of traffic, mapping, urban management, navigation electronic map generation, public safety, disaster and 3D modeling, etc.

Urban underground structures (e.g., subways) and hazards (e.g., voids) elude non-penetrating airborne imaging/laser scanning. Vehicle-borne ground-penetrating radar uses dielectric contrasts, emitting high-frequency pulses underground via antennas. Via wave penetration, it infers target depth, structure and properties from reflection/transmission parameters (e.g., delay, amplitude) at electrical interfaces. With shallow accuracy, efficiency, non-destructiveness, penetration and high resolution, it’s widely used in urban, geophysics, structural/road/bridge/tunnel inspection, and underground detection, etc.

Engineering measurement spans the full engineering lifecycle (surveying, design, construction, management), providing reliable, accurate spatial data for design, construction, operation—supporting project operation, speed, quality, effectiveness. Deformation monitoring, a key part, observes, analyzes, forecasts object deformation (phenomena, forms, development) with professional tools/methods. It monitors spatiotemporal deformation under loads/external forces, applied to mine surfaces, dams, bridges, buildings, etc.——supporting construction and structural safety.
