Product Profile
Introduction
The Livox Avia is a highly reliable and lightweight LiDAR sensor that features a long detection distance, high
precision, and wide field-of-view (FOV). It can be used for a wide range of applications such as robotics,
mapping, and vehicle-to-everything (V2X).
High Detection Range: The Avia has significantly optimized the detection range of low reflectivity objects (e.g.,
rebar, concrete, rock, or soil) by 70%.
Light Weight: The compact and portable Avia weighs just 498 g, making it suitable for drone mapping and
small robots.
Triple Return: Firmware supports up to triple return in mapping so as to better meet the needs of forestry
mapping.
Alternative Scanning Patterns: The Avia supports both non-repetitive and repetitive scanning patterns. Non-
repetitive scanning technology is used to improve the static scanning effect and the effect for the vertical plane
during on-the-fly mapping. Repetitive scanning technology is used for better density uniformity of point cloud data.
Built-in IMU Module: The model of the built-in inertial measurement unit (IMU) is BMI088 and the push
frequency is 200 Hz.
User-Friendly Livox Viewer: Livox Viewer is a computer software designed for Livox LiDAR sensors and Livox
Hub. Users can check real-time point cloud data of all the Livox LiDAR sensors connected to a computer and
also record the point cloud data to view offline or for future application. The simple interface makes it easy to use.
Open-Source Livox SDK: A software development kit (SDK) is provided to help develop customizable applications
using the data acquired from the point cloud data. Livox SDK supports Windows, Linux, Mac OS, and ROS.
The Avia has a detection range of up to 320 m, which can be reached when the target object
reflects 80% or more of light. For reference, grey concrete walls and roads have a reflectivity
range from 15% to 30%, while white plaster walls have a reflectivity range from 90% to 99% in an
environment with a temperature of 25° C (77° F) and a solar illuminance of 100 klx.
Before using for the first time, remove the screen protector from the optical window.
Product Characteristics
The Avia utilizes Livox’s unique scanning technology and provides two scanning point cloud patterns: non-
repetitive scanning patterns and repetitive scanning patterns. Users can choose the scanning pattern according
to their requirements. When using non-repetitive scanning, the scanning density is denser in the center of the
FOV compared to the surrounding area. For non-repetitive scanning point cloud patterns, the Avia has a FOV
of 77.2° vertically and 70.4° horizontally. In the center of the FOV within a radius of 10°, the point cloud density
rivals traditional 32-line LiDAR sensors within 0.1 s and traditional 64-line LiDAR sensors within 0.2 s. The point
cloud density in the rest of the FOV rivals traditional 32-line LiDAR sensors within 0.2 s. Over time, the point
cloud density and coverage inside the FOV increase significantly and reveal more detailed information of the
surroundings.
