Faster and Data Reduced Solution for High-resolution LiDAR Systems

TimestampsAI is our latest development for your applications to capture complex scenes in 3D in any environment.

Distance Determination Method TimestampsAI

Our distance determination method TimestampsAI bypasses data-driven problems for all future LiDAR sensor solutions. A pixel-wise quality information given in addition to the resulting point cloud allows confident decision-making of automated systems.

With the compact feature extraction and machine learning algorithms directly based on LiDAR timestamps, future LiDAR systems can be more efficient, effective and robust.

In factory automation and autonomous driving applications, complex scenes are required to be precisely captured with 3D sensors. Therein, high-resolution LiDAR systems are one promising solution. 

Such LiDAR systems generate a large amount of data, bringing great challenges to data transmission and processing on a resource-constrained embedded system.

With our services, such as TimestampsAI, you can overcome these issues and get smarter and faster LiDAR solutions for your products. Check out, what Fraunhofer IMS can do for your LiDAR systems.
