BlueCapLidar® Drone LiDAR System with Dual Livox Avia
BlueCapLidar® is a BlueCap-operated dual-Livox Avia drone LiDAR system with protected optics, four-IMU fusion, RTK and controlled point-cloud processing.
Dual-sensor payload · protected optics · one synchronised data chain
BlueCapLidar® is the airborne measurement and processing architecture inside BlueCap's large-area drone LiDAR survey service. It is not sold or rented separately. This page explains how two scanners see the ground, how their optics are protected, how position and attitude remain connected to every return, and how the raw record enters the controlled processing workflow.
Two scanners. One integrated payload.
Two DJI Livox® Avia scanners are fixed 32° apart in a vibration-damped basket purpose-built for BlueCapHeli®. The basket, four inertial sources, RTK positioning, onboard computer and local storage operate as one acquisition unit.
BlueCap-designed and BlueCap-operatedThe payload, aircraft, acquisition and processing workflow remain one accountable survey system. The hardware is not sold or leased separately.
Reflected points / second
Combined registered point output
Fused inertial architecture
Two scanner, one basket and one carrier IMU
Surface window at 100 m AGL
45,600 m² · 4.56 ha instantaneous view
Protected optics
One powered shutter covers each LiDAR window during ground handling and take-off.
Isolated basket
Vibration dampers separate the field-swappable scanner assembly from the carrier.
Navigation fusion
Four IMUs and configured 0.8 cm horizontal RTK resolve position and attitude.
Local record
An onboard computer and 2 TB SSD retain LiDAR, inertial, RTK and telemetry data together.
Protected optics open onto a wide ground view.
The scanners are angled to create complementary ground-facing views rather than advertise a full-sphere envelope. At 100 m AGL the combined instantaneous surface window is approximately 285 m across track by 160 m along track.

01 · ground and take-off
Two shutters isolate the optical windows
Rotor-wash dust, grit and droplets stay away from both scanner apertures while contamination risk is highest.
02 · after climb-out
Full apertures open for acquisition
Cleaner windows preserve laser transmission and usable reflected returns before the first production line.
Every return keeps its position, attitude and flight context.
BlueCapLidar® does not treat the point cloud, inertial solution and aircraft record as separate files to reconcile later. The measurement channels share one locally recorded, time-connected acquisition stream.
Scanner A IMU
Inertial parameters remain attached to the first Livox Avia stream.
Scanner B IMU
The second scanner retains its own measured motion and timing context.
Basket IMU
Payload motion is measured after the vibration-isolated mechanical interface.
Carrier IMU + RTK
Aircraft attitude, 0.8 cm configured horizontal RTK and telemetry complete the record.
One time-connected source record≈24 MCAP topics
Point clouds, four IMUs, RTK positioning and flight telemetry retain their shared acquisition context.
Compare the payloads on the same hardware questions.
These figures isolate scanner architecture, protected optics, registered point output, inertial sources, RTK and instantaneous surface geometry. They do not claim completed square kilometres per field day.

The payload ends in usable terrain products — not a disconnected point cloud.
The synchronised field record enters a BlueCap-controlled cloud workflow for preview, filtering, alignment, tiled stitching, classification, terrain generation, QA and delivery. The same engineering team controls both sides of the hand-off.
Source record
Dual point clouds, four IMUs, RTK and telemetry remain connected in MCAP.
Preview & batch
Browser preview exposes acquisition progress while flight batches enter the queue.
Filter & align
Returns are filtered and the two scanner streams are resolved into one geometry.
Tile & classify
20 m overlaps support seam checks as cluster nodes generate terrain classes.
QA & deliver
Products, metadata, coordinate systems and tile structures are packaged consistently.
