STH-DCSG-VAR Monochrome Sample Images

These images were taken with a monochrome STH-DCSG-VAR, using 12 mm lenses. Processing of the images was done by the SVS software on the the PC, to produce a disparity image (an image where brightness codes for distance). The disparity image was converted into 3D points. The 3D point conversion is very efficient, and takes only a few milliseconds.

With version 4.3f, SVS has added a speckle filter, to get rid of small "range speckles" in the disparity image. The resulting 3D image is much cleaner than without the filter.

TOP - Left image in monochrome - click on the image for the 640x480 version

MIDDLE - Disparity image, closer objects are brighter. Speckle filter with regions < 100 pixels eliminated. Click on the image for 640x480 version.

BOTTOM - 3D point cloud from stereo analysis - click on the image for a VRML animation. (2 MB VRML - You need a VRML plugin to view the 3D animation, e.g., Cortona). When the VRML image displays, click on the center to animate the point cloud. NOTE - the detached objects in the upper right are not noise, they are large flowers and parts of a tree in the foreground.
