A Paradigm Shift in Autonomous Driving: Hesai Introduces the World’s First Full-Color LiDAR Chip, "Picasso"

 Autonomous vehicle (AV) technology has advanced rapidly over the past decade, yet a fundamental limitation has persisted in environmental perception: the lack of native color recognition in Light Detection and Ranging (LiDAR) systems. Historically, LiDAR has mapped environments exclusively as monochromatic 3D point clouds. Hesai Technology has recently addressed this critical gap with the introduction of "Picasso," the world's first full-color LiDAR chip, marking a significant milestone for the future of autonomous mobility.

​The Limitations of Traditional Sensor Fusion

​Conventional LiDAR systems excel at determining distance, shape, and spatial coordinates. However, distinguishing critical visual details—such as the state of a traffic light or the specific markings on a road sign—has strictly required supplementary camera data.

​The standard industry practice of software-level "stitching" (sensor fusion) to combine LiDAR depth data with two-dimensional camera color data demands immense computational resources. This complex processing can introduce micro-delays and software "guesswork" during data synchronization, which poses potential safety risks in highly dynamic, real-world driving scenarios.

​Hardware-Level Integration: The Picasso Architecture

​Hesai's 5th-generation 6D full-color platform, Picasso, fundamentally resolves the latency and processing overhead associated with traditional sensor fusion. By integrating color perception and distance measurement directly at the hardware (ASIC) level, the sensor generates a native, full-color 3D point cloud.

​This pixel-level integration enables the vehicle's perception system to instantly identify traffic signs, lane markings, and road hazards with true-to-life color, entirely bypassing the need for post-processing alignment with external camera feeds.

​Technical Specifications and Capabilities

​The new 6-Dimensional (6D) architecture introduces unprecedented precision to the AV sensor market. Key technical specifications include:

​4K Ultra-High Resolution: Delivers exceptional environmental detailing, comparable to modern high-definition imaging.

​4,320 Laser Channel Support: Provides a massive increase in point density and scanning precision compared to legacy LiDAR systems.

​>40% Photon Detection Efficiency (PDE): Enhances long-range visibility and sensor sensitivity without increasing laser power consumption. The chip can accurately detect objects as small as a 15x25 cm wooden block from 150 meters away.

​6D Perception: Simultaneously captures an object's spatial coordinates (X, Y, Z), velocity, reflectivity, and true color in real-time.

​Accelerating Level 3+ Autonomy

​Industry experts anticipate that native full-color LiDAR will be a critical enabler for the safe and reliable deployment of Level 3 (L3) and higher autonomous driving systems. By eliminating the computational burden of software-based data matching, the Picasso chip allows the vehicle's central processing unit to make faster, more deterministic decisions. This will significantly reduce the hesitation and processing delays current systems experience in complex urban environments.

​Production and Implementation Timeline

​Hesai has confirmed that this hardware is actively moving toward commercialization. The new generation ETX series color LiDAR sensors, powered by the Picasso chip, are scheduled to enter mass production in the second half of 2026.

​As hardware-integrated color LiDAR is poised to become the new industry standard, it promises to significantly enhance the safety, reliability, and cognitive capabilities of next-generation autonomous fleets, effectively bringing an end to the monochromatic era of machine vision.
