    The Dynamic Calibrator tool is for the 400 Series of cameras (D415, D435, D435i, etc). The On-Chip Self Calibration feature is also a 400 Series feature.  There is no calibration tool for the SR300 / SR305, and calibration is performed at the factory during the camera's manufacture.

     

    SR300 / SR305 cameras do not usually require calibration though.  Unlike the Stereo imaging technology of the 400 Series cameras (which have a left and right IR sensor), the SR30x series uses a different depth sensing technology called Coded Light which uses only one IR sensor.  

     

    The SR300 was launched in 2016 and the 400 Series in 2018.  The SR305 is essentially an SR300 inside an improved casing and is intended to be an entry-level product for the RealSense product family.  Its technology and capabilities are therefore more limited in comparison to those of the 400 Series.  The white paper documents are written for the 400 Series cameras.

     

    The SR305 is though able to make use of post-processing filters.

     

     

    Overall, the SR305 works with the RealSense SDK software and programs associated with it, such as the RealSense Viewer, and you are able to write your own programs for it in the same way that can be done for 400 Series cameras.  Compatibility of the SR305 with older software designed originally for the SR300 model cannot be guaranteed though.

     

    If future-proofing is important to you then the D415 camera will be a good choice.  Its price is excellent value, it has around 2x better image quality than the D435 models and you can easily drop the latest RealSense L515 model into a project created for a 400 Series camera at a future date just by changing a few lines of code.

    Hi,

    Thanks for your great and detailed response.

    Just I would like to also know :

    + The SR3XX projects a fixed set of patterns that are stored inside its electronics at the factory?, or the patterns can be designed and uploaded by the user to the electronics of the device?

    + Which are the valid Windows operating systems to run the RealSense Viewer, the Depht Quality Tool, and the RealSense SDK for the SR3XX, D415, D435i and L515 products?

    + And just a last one: is there any date planned to launch the L515 product that you mentioned? (i mean to get it if i make now a pre-order)

    Best regards.

    You're very welcome!  In answer to your new questions:

    1.  Regarding questions about the Coded Light patterns, I will refer you to the guidance of a guy called Samontab who was an expert on the subject in 2016, even writing a laser control utility.

    https://software.intel.com/en-us/forums/realsense/topic/537872 

    Samontab discusses the pattern tech in terms of the SR300's predecessor the F200 but they were both Coded Light cameras and the hardware was very closely related (the SR300's original model was back-compatible with F200).

    A more advanced research paper PDF on the SR300's technology is here:

    https://vista.cs.technion.ac.il/wp-content/uploads/2019/05/IVCAMPAMI19.pdf 

     

    2.  The RealSense SDK 2.0 software supports the 400 Series, SR30x, T265 and L515 on Windows 10.  There is also a separate version of the SDK for Windows 7.  The 400 Series and T265 support both USB2 and USB3, whilst the SR30x requires USB3.  The data sheet document for the L515 lists minimum requirements of USB 3.1 Gen 1 and Windows 10 (build 15063 or later).

     

    3.  Pre-orders placed for the L515 after March 31 ship in the week of July 26, according to the L515's listing in the official RealSense store.  I do not know yet whether they are extending the pre-order period further after July 26 or it will switch to normal in-stock retail. 

     

    I should mention that the SR30x and L515 cameras are suited to use indoors or under controlled light conditions in case your application is outdoors.

    Hi,

    Thanks for your response.  And what about the Windows operating system for the RealSense Viewer and the Depht Quality Tool applications?. It is possible to properly run this applications for the SR30X, the D415, the D435i and L515 in Windows 8.1? . Or just Windows 10 (and maybe Windows 7)?

    Windows 7 supports D415 and D435.  The D435i does not yet have Windows 7 support.  It could be provided in a future SDK release.

    My interpretation of information about Windows 8.1 is that it would work with D415 and D435 but support for camera metadata would not be available.  I could not find confirmation that D435i is compatible with Windows 8.1.

    L515 and SR30x require Windows 10.

    Thanks for your response. Just a last clarification: it is enough with Windows 10 Home 64bits, or Pro 64bits is needed?

    Windows 10 Home should be fine.  It is what I have on my personal workstation that I use with RealSense SR300, D415 and D435i.
