Abstract
This invention provides a system and method for the high-accuracy measurement of an object's surface displacement at a plurality of measurement points using a laser displacement sensor and a sensor process that corrects for noise and other accuracy-reducing factors. A camera assembly with an imager and optics package acquires images of an object surface, and a laser assembly projects a line on the object surface. These tasks can include (a) defining patches of the surface based upon a grid; (b) registering the object and aligning the grid with respect to the object; (c) excluding from the analysis of the image, irregular surface features; (d) oversampling one or more patches to improve overall accuracy; (e) specifying measurement resolution (i.e. in the (x, y z) dimensions), including choosing appropriate pixel sizes and number of measurements per measurement point; and (f) selecting optimal acquisition/image formation parameters.
