Tie a long string to a paperweight. Pick up the weight using the string’s far end and move it as fast as you can several feet. The weight will probably swing back and forth in a predictable pattern. Now imagine a variable-speed fan blowing randomly on the weight. How do you move it precisely and rapidly with little or no sway? That’s the challenge facing crane operators. Fortunately, there’s a solution. But, getting it right took engineering and time, as well as machine vision technology and proper camera selection, according to Joseph Discenza. He’s president and...Read full article
