Product Profile

Introduction

Livox HAP features a long detection range, high precision, wide field-of-view (FOV), and 
high reliability. It can be used for multiple applications, including autonomous driving, robots, 
automated guided vehicles, and unmanned aircraft. Livox HAP has two models, which are HAP 
(T1) and HAP (TX). This document is intended for HAP (TX).

High FOV Coverage: 

The HAP (TX) utilizes Livox’s unique non-repetitive scanning technology and 

multi-laser and multi-APD DL-Pack technology, which can quickly detect every detail inside the FOV.

Wide FOV: 

The HAP (TX) has a rectangular FOV of 120° horizontally and 25° vertically. The HAP 

(TX) scans horizontally from top to bottom, increasing its compatibility with algorithms used to 
process common point cloud data.

High Reliability: 

The HAP (TX) offers enhanced reliability as the cutting-edge design works 

normally without rotating internal electronic devices such as the transmitter and receiver.

Environmental Adaptation: 

Even under 100 kilolux conditions, the HAP (TX) boasts a low noise 

rate below 0.01%. The HAP (TX) can effectively reduce interference from other LiDAR sensors 
thanks to the innovative de-noising algorithms built into the unit.

User-Friendly Livox Viewer 2: 

Livox Viewer 2 is software specially designed for Livox LiDAR 

sensors. It displays and records real-time point cloud data, replays point cloud videos and 
analyzes the 3D point cloud data. Users can set product parameters and calibrate extrinsics 
using Livox Viewer 2. 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/ROS.

 The HAP (TX) has a detection range of up to 200 m, which can be reached when the 

target object reflects 35% of light or more. 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).

  Before using for the first time remove the screen protector from the optical window.
