    Industrial robots have been adopted in factories worldwide for more than fifty years. In recent years, due to ever increasing wages, diminishing worker supply and shortened product life in consumer electronics, robots are required to be more intelligent for purpose of cooperation with human and even replacement of some workforce. Now most automatic inspection machines are designed to target testing objects which have flat surfaces and simple shapes, and hence are unable to handle those with multiple and shiny surfaces or irregular shapes. Eye-in-hand machine vision technology enables the enhancement of the flexibility of the inspection system on the manufacturing line. It integrates the optical system (including flexible illumination and image capture) on the robot arm. As the robot arm moves, it captures and processes 2D or 3D images of the testing object from different angles.

    This project aims to develop an eye-in-hand flexible visual inspection platform, on solving the problems of inspecting free form surfaces and realizing automatic surface inspection for complex shape products of automotive component and home appliance. To achieve this goal, the project team will develop the following IP protected platform technologies, including (1) 2D EiH flexible inspection platform which bases on hybrid light field illumination and deep learning based background subtraction algorithm (2) 3D EiH flexible inspection platform which bases on high resolution illumination and image capturing system, embedded 3D image processing unit and curve embedding distributional outlier detection algorithm.

    The global size of machine vision system market is USD 1.52 billion in 2014 and is estimated to reach USD 5.49 billion in 2019. In China, the potential market of machine vision can even reach RMB 96 billion per year. Hong Kong government has been taking many efforts to promote and support the Innovative and Technology industry, as well as the initiatives of “Hong Kong Re-industrialization” and the “Guangdong-Hong Kong-Macao Big Bay Area (GHMBBA)” The technologies developed in this project will strengthen the competitiveness of Hong Kong and China companies in this rapid growing industrial robot market.
