Further Simplified 2-Step Operation
Even when the target has an uneven surface, a fully-focused image can be obtained instantaneously by compiling images of different focus positions. The 3D display allows surface shape observation from various angles. When the Z-axis electric stage is used, this quick 3D image can be displayed easily by just pressing the console button twice.
We have adopted a new algorithm that uses the fine changes in texture to estimate height data. Building on our depth-up feature, whereby a fully focused image can be constructed from a small number of images, the D.F.D. method facilitates the accurate construction of a 3D model allowing for versatile observation in three dimensions.
The D.F.D. method is the process by which the VHX can 1.) Compile a completely in-focus image, or 2.) Generate data to compile a 3D model. The D.F.D. method analyzes the level of contrast, or focus at each level of the target. By using the degree of blurring, the D.F.D. method can calculate height information for each pixel, thereby enabling the compilation of a 3D model or a completely in-focus image. Even if a pixel cannot be captured in perfect focus, a calculation is made to generate height data. The D.F.D. method exponentially increases the efficiency of a 3D construction.
Edge displacement and image blurring due to camera-shake while capturing an image with a non-telecentric lens are automatically corrected, and a comprehensive, completely focused image is constructed. This method is at least five times faster and more accurate than conventional position correction methods, and obtains accurate information even for easily distorted, low magnification areas.
Once applicable only to still images, we’ve now enabled the glare removal function to be used on live images and 3D display. By removing the reflectivity, the accurate 3D display of the target surface becomes possible.
