A twelve-head masthead ring that stitches low-light colour and uncooled thermal imagery into one continuous horizon, then detects, classifies and tracks every surface contact in it — including the small wooden craft that never appear on AIS or radar.
The problem
What this exists to solve.
A bridge watch on a warship or a bulk carrier is asked to hold a continuous visual lookout under COLREG Rule 5 — in glare, in haze, at night, through a night-vision device, for four hours at a stretch. Radar loses small wooden fishing craft in sea clutter. AIS never had them to begin with: carriage rules only bind cargo ships over 300 GT and passenger ships, so the most collision-prone traffic in Indian coastal waters is precisely the traffic that is electronically invisible.
Our approach
How DRISHTI-360 handles it.
DRISHTI-360 treats the horizon as a single continuous image rather than a set of camera feeds. Twelve heads — six low-light colour, six uncooled LWIR — are factory-calibrated as a rigid rig, stitched into one cylindrical panorama and stabilised against pitch and roll using the ship's own attitude reference. Detection runs on the stitched panorama, so a contact crossing a seam is one track, not two.
Capability
What it does well.
Seam-free tracking
Detection runs on the stitched cylinder, so a contact never fragments into two tracks as it crosses a camera boundary.
Dark-vessel emphasis
Models are weighted toward the non-AIS traffic that dominates Indian coastal waters — country craft, gillnetters, dhows and unlit skiffs.
Glare and monsoon hardening
Trained on Arabian Sea and Bay of Bengal footage across sea states 0–6, including south-west monsoon rain and post-monsoon haze.
Range and bearing at the alert
Every track carries a horizon-geometry range estimate and true bearing, ready to hand to ARPA or the autopilot.
Recorded evidence
Rolling encrypted buffer with track overlay, exportable for incident review or class investigation.
