Higher Image Resolutions for SP1
A new update to firmware version 1.3.0 has been released today for the SP1 stereo vision sensor. The most important change in this release is the support for image resolutions above 640 x 480 pixels. Image resolutions can now be configured by the user, who has a choice between lower resolutions at high frame rates, or higher resolutions at lower frame rates. We currently recommend the following two configurations:
- 640 x 480 pixels at 30 fps
- 800 x 592 pixels at 20 fps
Of course, other combinations of frame rates and image resolutions are also possible. The SP1 can now process images with a size of up to 800 x 800 pixels. The user is able to test different resolution and frame rate combinations for finding the settings that work best for his application.
In order to support different image resolutions without the need for changing cameras, a region of interest (ROI) and pixel binning can be configured. When using image resolutions other than 640 x 480 pixels, please also update your API to version 2.1.1. This release fixes a bug that otherwise prevents the use of specific resolutions.
Higher image resolutions also mean that lens distortions lead to higher deviations between the ideal and actual projection for a given pixel. We have thus increased the allowed rectification range from +/-31 pixels to +/-39 pixels. Together, these changes should make the SP1 an even better sensor for real-time depth sensing.
