The most noticeable change to the SP1’s processing capabilities is the support for increased image resolutions. At its market launch, the SP1 only supported a small image resolution of 640 x 480 pixels. By now, this system is capable of processing images with a resolution of up to 1440 x 1440 pixels, and it can produce an equally sized depth map. This is more than a sixfold increase compared to the original specifications.

Likewise, the measurement accuracy has also increased significantly. For stereo vision, the measurement accuracy highly depends on the size of the region that is searched for image correspondences, the so called disparity range. Initially the SP1 supported a fixed ranger of 96 pixels. Since the most recent firmware update, the SP1 can now search a range of up to 256 pixels, which more than doubles the depth resolution.

When configuring the image and depth resolution, the customer has a choice between a fast processing rate or high resolution results. The customer also has the choice of cameras, their positioning, and the employed optics. This makes the SP1 one of the most flexible sensor systems that can be applied to even the most dissimilar use cases.
