SUN Xue-yan. Design and experiment of distance measuring system with single camera for picking robot[J]. 2010, 29(3): 80-81+88. DOI: 10.13873/j.1000-97872010.03.030.
A new method of distance measuring by single camera for picking robot is presented.Experimental system of open picking robot based on PC is developed.The automatic threshold is adopted to segment the G-B gray images of the target.The characteristics of fruit target such as outline
area
center of gravity
enclosing rectangle and the point to cut off
are extracted through outline tracing.Testing program is written based on Visual C++ 6.0 according to the distance-measuring theory.Experimental results show that measurement error is within ±18 mm when the measuring distance ranges from 275 mm to 575 mm.The system work stably and can meet working demand of the picking robot.
