Unleash Real-Time LiDAR Intelligence with Akida On-Chip AI
What is a LiDAR Point Cloud and Why is it the Foundation of Spatial AI
LiDAR (Light Detection and Ranging) technology is the key enabler for advanced Spatial AI—the ability of a machine to understand and interact with the physical world in three dimensions. A LiDAR sensor pulses laser beams to create a highly accurate, three-dimensional map of space, which is compiled into a LiDAR Point Cloud.
This 3D map is known as a LiDAR Point Cloud.
A point cloud is a massive collection of data points, where each point represents a specific coordinate (X, Y, Z) in the environment. It essentially creates a rich, detailed digital twin of the surrounding space, packed with geometric information about objects, infrastructure, and terrain.
The Critical Importance of 3D Spatial Perception
For next-generation applications like autonomous vehicles, advanced robotics, and intelligent infrastructure, the point cloud is the gold standard for spatial perception because it provides:
- Unmatched Precision: Highly accurate distance and volume measurements, essential for safe navigation and manipulation.
- Depth and Geometry: True 3D context that is not susceptible to the lighting and occlusion issues of standard 2D imaging.
- Instant Interpretation: Enables devices to instantly interpret complex environments for object classification, obstacle detection, and path planning.
The Problem: Cloud-Dependent LiDAR Creates Dangerous Delays
While the data is invaluable, the sheer volume of a point cloud creates a critical processing challenge. To analyze this data, many systems rely on centralized computing or cloud.
The issue? The round-trip journey to the cloud introduces latency.
In time-sensitive scenarios—like an autonomous vehicle needing to identify a sudden obstacle or a robotic arm requiring immediate process control—this delay is unacceptable. This reliance on off-device processing prevents systems from turning massive datasets into instant, real-time decisions, posing a safety and operational risk. To achieve true instant action, the heavy lifting of point cloud analysis must happen directly on the device—a requirement known as the Edge AI Imperative.
The Solution: Unleashing Real-Time 3D Intelligence with BrainChip’s Akida ™
BrainChip addresses this critical latency challenge with the Akida™ PointNet++ model—an advanced, on-chip point cloud AI solution adapted from the original PointNet++ architecture. *
The Akida PointNet++ model is a compact, neuromorphic-friendly neural network that is uniquely optimized to perform real-time classification of 3D LiDAR point clouds directly at the edge. By running this sophisticated model on a hyper-efficient neuromorphic processor, the key benefits are immediately realized:
- Real-Time Responsiveness: Selective data handling delivers instant decision-making for streaming applications where milliseconds are crucial.
- Energy Efficiency: The system operates in the milliwatt range, making it ideal for battery-powered, always-on, and field deployments.
- Ultra-Compact Design: The processing runs efficiently, even on memory-limited edge devices without compromising performance.
How Akida Point Cloud Delivers Speed and Efficiency
What makes the Akida approach uniquely suited for sparse, unordered LiDAR data is its architecture, which maximizes efficiency and accuracy:
- Native 3D Processing: Unlike traditional methods that often convert the 3D point cloud into grids or images, the Akida PointNet++ model works natively on the raw point sets. This preserves data integrity while maximizing efficiency.
- Sparsity-Driven Efficiency: Akida’s architecture processes only the most meaningful LiDAR data points. This focus eliminates computational waste associated with processing empty space or redundant data, enhancing both speed and model accuracy simultaneously.
- Hierarchical Learning: The model utilizes a Hierarchical PointNet++ Backbone to capture both fine-grained local details and the overall global context of the 3D shape, boosting accuracy on sparse, large-scale data.
