Accurate planar area and contour length measurement
نویسنده
چکیده
This paper describes a technique for accurately estimating the area and contour length of a planar non-polygonal region in the scene. The approach taken is to formulate a continuous model of the boundary of the region in the scene and use the image data to estimate the parameters of the model. The required information is then extracted from the model parameters. A high order trigonometric polynomial is used to model the region boundary which leads to a simple formula for the region area. The contour length is obtained using a high order numerical quadrature technique. Results of experimental evaluation are shown.

متن کاملHybrid Vision/Force Control at Corners in Planar Robotic-Contour Following
The accuracy and execution speed of a force controlled contour-following task is limited if the shape of the workpiece is unknown. This is even more true when the workpiece contour contains corners. This paper shows how a hybrid vision/force control approach at corners in planar-contour following results in a more accurate and faster task execution. The vision system is used to measure online t...
