GPS is a technology or system which is used to trace an targeted object on earth from a distance with the help of group of Satellites.. Global Positioning System–GPS is no longer a buzzword today. GPS technology is one of the most valuable technological breakthroughs till date, benefiting everyone. In fact, GPS technology is so diverse that you can find its applications in almost every industry. Initially used for military purposes, today, Uber and delivery service providers rely on GPS to provide efficient services to customers. Michael . Lombardi.

Firstly, data sets of workpieces with three different shapes (cube, cylinder and sphere) are established, and the YOLOV3 target detection algorithm is used for deep learning to realize intelligent recognition of different shapes of workpieces. Then by the use of binocular machine vision technology, the key points position of workpieces can be successfully detected with relative error less than 2 %. This workpiece detection and positioning system can be introduced in the mechanical arm grabbing control system to make it has the visual ability similar to human in order to realize mechanical arm intelligent grabbing in complex environment..
