Airy 192-beam Hemispherical Digital LiDAR: A Precision Tool for High-Resolution 3D Mapping

Shenzhen Mingjiada Electronics Co., Ltd. specialises in electronic component sales and recycling services. With its extensive product selection, precise supply chain management, and comprehensive technical support, it has become a significant force in the electronic component recycling and distribution sector.

The company currently supplies and recycles the Airy 192-beam hemispherical digital LiDAR, featuring 1 cm @ 1σ accuracy and a 360° × 90° field of view, making it ideal for high-resolution 3D mapping.

Amidst the rapid advancement of 3D mapping technology, demands for detection precision, field-of-view coverage, and device integration continue to intensify. As the world's first 192-beam hemispherical digital LiDAR, Airy redefines the performance benchmark for high-resolution 3D mapping. Its ultra-high accuracy of 1 cm @ 1σ, comprehensive 360° × 90° field of view, and integrated advantages from its digital architecture deliver revolutionary solutions for diverse indoor and outdoor surveying tasks.

Core Performance Breakthrough: Dual Summit of Accuracy and Field of View

Precision is the lifeline of 3D mapping. Airy achieves 1 cm @ 1σ ranging accuracy through breakthrough technology, far surpassing mainstream surveying-grade LiDARs and enabling millimetre-level capture of intricate scene details. This precision advantage stems from its next-generation VCSEL transmitter chip and high-sensitivity SPAD-SOC digital detection chip. Its digital transceiver solution directly converts optical signals into digital data, eliminating the analogue-to-digital conversion stage found in traditional radar systems. This approach entirely circumvents signal transmission noise and distortion, ensuring zero loss of echo information and laying a robust foundation for mapping data accuracy.

Regarding field-of-view coverage, Airy leverages RoboSense's unique opto-mechanical system design to achieve complete hemispherical coverage spanning 360° horizontally and 90° vertically, with a detection radius of 60 metres. This enables seamless, single-pass scanning of entire scenes without blind spots. Compared to traditional LiDAR systems with field-of-view blind spots and stitching errors, Airy acquires comprehensive 3D data without multiple device repositioning, significantly boosting surveying efficiency. It is particularly suited for rapid modelling demands in complex terrains, confined spaces, and large-scale environments. Combined with a high-frequency point generation rate of 1.72 million points per second and ultra-high 192-line resolution, the generated point cloud data exhibits orderly arrangement and uniform density. This enables precise reproduction of object contours, terrain undulations, and spatial details, providing high-quality data support for subsequent modelling and analysis.

Digital Architecture Empowerment: The Perfect Balance of Miniaturisation and Stability

Airy redefines LiDAR design through digital architecture, resolving the inherent trade-off between performance and size found in traditional analogue systems. As the industry's first compact, lightweight hemispherical digital LiDAR, its entire unit measures just 60mm in diameter and 63mm in height, weighing under 240g – comparable in size to a table tennis ball. This enables flexible integration onto diverse mobile platforms such as drones, AGVs, and surveying robots without requiring substantial installation space, adapting to both indoor and outdoor multi-vehicle surveying scenarios. Furthermore, its power consumption is controlled below 8W, enabling prolonged continuous operation. This significantly extends endurance for field surveying and large-scale inspections, ensuring efficient task execution.

The digital architecture delivers more than just size and power optimisation; it markedly enhances environmental adaptability and reliability. By employing digital algorithms to filter environmental stray light interference, Airy maintains stable accuracy under complex lighting conditions such as intense sunlight or fog, facilitating continuous all-weather surveying operations. Compared to traditional analogue radar systems reliant on complex discrete components and susceptible to temperature drift, Airy employs a chip-level integrated solution. This reduces mechanical wear and failure probability while simplifying calibration procedures. It operates reliably across a wide temperature range of -40°C to 85°C and in harsh outdoor environments, meeting the stringent demands of industrial-grade surveying.

All-scenario adaptability for high-resolution 3D mapping

Airy's performance characteristics align perfectly with the core demands of high-resolution 3D mapping, delivering exceptional value across multiple industry applications. In indoor surveying, whether modelling warehouse shelving layouts, restoring ancient architectural details, or conducting underground space 3D mapping, its 1-centimetre precision accurately captures beam/column dimensions, floor flatness, and artefact textures. The 360° hemispherical field of view comprehensively covers concealed areas like ceilings and wall corners, generating high-density point clouds directly usable for 1:500 scale high-precision drafting.

In outdoor surveying scenarios, Airy can be deployed with drones to undertake terrain reconnaissance, road engineering mapping, and park 3D modelling. Its 60-metre detection radius and high-speed point cloud output capability enable rapid coverage of extensive areas while accurately reproducing terrain undulations, vegetation distribution, and building contours. This significantly reduces operational cycles compared to traditional surveying methods, achieving high-precision modelling without reliance on extensive ground control points. In smart port and industrial plant applications, it collaborates with AGVs and unmanned forklifts for environmental modelling and path planning, providing precise spatial data support for automated operations and driving the intelligent integration of surveying with maintenance.

Technological Innovation Shaping the Industry's Future

The introduction of the Airy 192-beam hemispherical digital LiDAR represents not only a significant milestone in the advancement of LiDAR technology towards higher resolution, miniaturisation, and digitalisation, but also injects fresh vitality into the high-resolution 3D surveying sector. Through the deep integration of chip-level integration, digital signal processing, and extreme performance design, it addresses the pain points of traditional surveying equipment—such as insufficient accuracy, limited field of view, and deployment inconvenience—enabling high-precision 3D surveying to move beyond specialist laboratories into broader industrial applications.

Moving forward, as digital LiDAR technology continues to evolve, Airy will further leverage firmware upgrades to optimise performance and expand its application boundaries into more high-end surveying scenarios. This will deliver more efficient, precise, and convenient solutions for fields such as geographic information collection, engineering construction, and smart operations and maintenance, thereby supporting digital transformation and intelligent upgrades across diverse industries.
