Optidepth is an AI-powered safety system that enables real-time collision prevention for heavy machinery at a fraction of the cost of traditional solutions. By leveraging optimized monocular depth estimation with quantized MiDaS neural networks on edge devices such as Jetson Nano and Raspberry Pi 4, the system transforms standard cameras into intelligent monitoring tools. Optidepth achieves 15-20 FPS, a detection range of 0.5−5 meters, and sub- 100 ms alert latency with an accuracy of 92%, requiring no additional hardware modifications for deployment. Delivering LiDAR-grade perception capabilities purely through software, the system addresses critical safety challenges in construction, including worker protection, prevention of utility strikes, and reduction of equipment damage. Its scalable, retrofit-ready architecture with support for over-the-air (OTA) updates makes Optidepth a practical and cost-effective solution for enhancing industrial safety in a market valued at over $ 50 billion.
