Gray scale processing via video edge probes
The black and gray portions of a workpiece are digitally classified into 256 gradation levels, then edges are detected and processed based on this classification. This prevents measurement data from being affected by changes in illumination.
Video edge probes with auto "best-fit" function
When the operator clicks the point to be measured, the system automatically rotates the probes, sets them at the optimum position, and sets the probe size, all automatically.
Easy selection of desired edges by eliminating dust and burrs
Some workpieces contain multiple edges within a given caliper, or their contrast is too low, making edge detection extremely difficult. This function graphically profiles the contrasts of the image within the caliper using a multi-gray-level scale, enabling the operator to select any one of a number of edges. Selection of the desired edge is simple: click the appropriate buttons in the edge selection menu and adjust a threshold level using the mouse.
Enhanced edge detection with Nikon's unique algorithm
Thanks to Nikon's proprietary edge detection algorithm (patent pending), detection of edges at low magnifications is now possible with excellent precision. This enables the detection of minute, low-contrast edges, a task that is difficult to perform using gray scale processing. Image recognition capability almost equal to the human eye and a detection speed among the world's fastest allow the system to measure any workpiece with unrivaled precision.
