CHCNAV AU20 AP7 Dual-Head Mobile Mapping System

Name: CHCNAV AU20 AP7 Dual-Head Mobile Mapping System
Brand: CHCNAV
Availability: InStock

The AU20 AP7 dual head runs two AlphaUni 20 lasers on the next-generation AlphaPano AP7 vehicle platform, with up to eight cameras – Ladybug5+, Ladybug6, Basler and others – for complete, blind-spot-free road capture.

At 60 km/h it delivers 4 cm line spacing and 6,000 pts/m², with 20 mm horizontal and 10 mm vertical accuracy.

Key features

Dual-head scanning – Two AU20 lasers eliminate blind spots and double density.
Up to 8 cameras – LD5+, LD6, Basler and other cameras simultaneously.
Survey-grade vehicle data – Hz 20 mm, V 10 mm in normal GNSS conditions.
Ladybug6 panoramas – 72 MP (6 × 12 MP) at 15 FPS for detailed asset imagery.
Still multi-platform – Each AU20 head also flies on UAVs or works in a backpack.
Full software suite – CoPre and CoProcess with road and building extraction.

CHCNAV AU20 on the AlphaPano AP7 dual-head vehicle platform

Built for highways and corridors

Two scanners, twice the coverage

Two AU20 heads scan the road from two angles, eliminating shadows behind vehicles, poles and barriers. Add a Ladybug6 for 72 MP panoramas at 15 FPS, and you have survey-grade road inventories, pavement and asset data in one drive. For a lighter single-head kit see the AU20 AP5.

Dual-laser scanning

4 cm line spacing at highway speed

Two AU20 heads at 2 million measurements per second each capture pavement, curbs, signs and structures on both sides of the road at once. At 60 km/h the dual-head setup gives 6,000 pts/m² and 4 cm line spacing (single-head AP7: 4,000 pts/m², 8 cm).

Dual head: 4 cm, 6,000 pts/m²
Up to 16 returns; 10 at 1.5 MHz, 8 at 2 MHz
Full waveform

Multi-camera imaging

Ladybug5+, Ladybug6 or your own cameras

The AP7 platform accepts mainstream panoramic cameras and up to eight cameras simultaneously. Ladybug6 delivers 72 MP (6 × 12 MP) at 15 FPS; Ladybug5+ gives 30 MP at 10 FPS in a lighter 3.0 kg package.

Ladybug6: 72 MPLadybug5+: 30 MPUp to 8 cameras

High-density point clouds

Complete roadside capture

Dense, shadow-free point clouds make it easy to extract lane markings, curbs, barriers, signs, poles and building façades for design, maintenance and as-built work.

CHCNAV AP7 vehicle mobile mapping city street data collection

Efficient workflow

Road and building extraction built in

CoPre processes POS, generates point clouds and imagery, runs strip adjustment and GCP refinement, optimises noise and builds DOMs and 3D models. CoProcess extracts terrain, roads, buildings and volumes.
