Optical 3D Locating System
Developed by Elektronaut under the Blickwerk brand, this optical 3D locating system showcases our capabilities in advanced embedded and FPGA design. The system determines the 3D position of active infrared markers with millimeter-level precision — and does so in real time.
At its core is a coded infrared light principle: each marker emits a unique optical code, which is captured by a network of high-speed camera sensors. Each sensor performs local image processing to detect and decode marker signals with minimal delay. The resulting data from multiple sensors is combined to achieve highly accurate, low-latency 3D localization suitable for both indoor and outdoor use.
All electronics and embedded software for both the markers and sensors were designed and implemented by Elektronaut. Each sensor is powered by a Zynq UltraScale+ MPSoC FPGA, combining programmable logic for real-time image processing with an embedded ARM processor running control and networking software. This architecture enables tight synchronization, efficient decoding, and minimal system latency — without relying on external computation.
The markers are available in battery-powered and externally powered variants, featuring rugged, waterproof housings. Each includes a programmable ID, adaptive brightness control, and power-efficient infrared emission that remains reliable even under bright sunlight.
The system reflects Elektronaut’s expertise in FPGA-based vision systems, high-speed digital design, and embedded software integration — from concept and PCB layout to functional prototypes and field testing.
