Lane sensing and Lane warning devices are available in most high end vehicles today. These systems are expensive and feature rich and perform various complex operations. An Asian Product Incubation company contracted Axiom to assess the feasibility of developing a low cost lane warning device to monitor driver behavior by way of lane detection.

Axiom carried out a detailed feasibility study to establish the technical feasibility for realizing this design. Various sensing technologies were explored such as low cost color sensors, visible light sensors, 1D cameras and IR photodiodes.

A proof of concept was built using the chosen design vector. The proof of concept was tested on a scale model to maximize learning’s for downstream development. The concept feasibility was firmly established before committing $$ for downstream development.

• Feasibility study of various sensors to establish low cost road lane sensing
  
• Developed IR based color sensor to detect lanes
• The application was developed on 8 bit Cypress PSoC platform for tighter analog – digital integration
• Modified Kalman Filtering algorithm was developed to eliminate false alarms
• Prototype was fabricated to test the chosen low cost sensor option
• The prototype was mounted on a 1:20 scale model Radio Controlled SUV. The scale model was tested on a 1:20 scale model of a typical US Highway complete with lane markings printed on a matt vinyl sheet
• The sensor data was streamed to a PC through a wireless connection. Scale model testing was conducted for a month
• Learning's from the scale model feasibility tests were used to select viable technologies and to evolve product specs for use as inputs for detailed design and development

Result :

• The product prototype was tested and deployed
