A navigation system includes: a control circuit configured to: a control circuit configured to: capture a sensor data stream provided by optical sensors, extract lane lines from the sensor data stream, optimize an extrinsic parameter and an intrinsic parameter based on the extract of the lane lines, and compile optimized parameters including the extrinsic parameter and the intrinsic parameter; and a communication circuit, coupled to the control circuit, configured to receive an optical sensor alert for displaying on a device.

Navigation system with automatic optical calibration mechanism and method of operation thereof

A method of operation of a navigation system includes: determining a geographic location, of a vehicle, while a global positioning location is blocked by an obstruction and the geographic location is from an in-vehicle location sensor in the vehicle; extracting an image line from a surrounding image with an artificial intelligence model and the surrounding image is from an in-vehicle image sensor in the vehicle; transforming an image coordinate of the image line to a world coordinate of a HD map local storage based on the geographic location; extracting a map line from the HD map local storage based on the world coordinate; determining a pose relationship between the image line and the map line paired as either horizontal or vertical; generating a map-related location for the vehicle based the geographic location and the pose relationship; and communicating the map-related location for displaying on a user interface.
