Module Calibration and Image Processing Based on Measurement System for 3-D Foot Shapes

摘要：

A method of module calibration and image processing based on a measurement system for 3-D foot shapes is described, which contains a module calibration system for the compensation of different position errors. A double scanning process with a calibration frame structure is performed, realizing thus a mapping conversion between the two coordinate systems. With the feature points formed by the intersection of the edges of the calibration frame and the light sectioning planes, different position errors can be automatically compensated. The disadvantages caused by the gradient prediction method can be reduced.Calibration and measurement experiments were conducted with satisfactory results.
