High-speed Image Stitching and Navigation Mode

Ultra high-speed image stitching function one push operation

Once the image stitching function has been activated, the XY stage will automatically move in a clockwise pattern and capture images at each location. After an image is captured, it will be stitched together with the previous image in real-time before the stage moves to the next location. This will provide users with a large (up to 20,000 x 20,000 pixels), overall view of the target, while preventing any misalignment typically associated with other stitching techniques.

Obtain high-resolution images with a large field-of-view
Because of the large depth of field, it was impossible to obtain a 3D topography at low magnifications.

Height information cannot be obtained from a
fully-focused image under low magnification. From a high magnification image, such information can be gathered by changing the focus positions.

Because of the large depth of field, it was impossible to obtain a 3D topography at low magnifications.

A 3D image is built based on 3D depth information obtained from the amount of out-of-focus blurring. Our low magnification lenses boast a large depth of field, making it impossible to distinguish different layers of focus. Consequently, it was impossible to construct a 3D profile at low magnification. By stitching together higher magnification 3D images, we are able to decipher the depth information over a large field of view. This algorithm has allowed for macro-level 3D compilations.

Navigation Function

XY stage illumination

The stitched image can be utilized as a navigation screen. Clicking on the position that you wish to observe will automatically move the stage to the selected location. The current field-of-view is outlined in a yellow frame and the previously viewed field-of-view is outlined in a red frame, making it easier to maneuver the stage. Also, when performing high magnification observation, this function is extremely useful for understanding which area of the target is being observed.


3D Image Stitching

By combining our Depth From Defocus algorithm for constructing accurate 3D images with our motorized XY stage, the VHX-2000 Digital Microscope is able to rapidly create a wide-field 3D image (up to 20,000 x 20,000 pixels). The 3D measurement functions can also be extended and applied to the stitched 3D image. This provides a better overall understanding of the surface of a sample and helps to eliminate variances in measurement results by including data from a larger area.
