About realsense SR300 depth data format and real distance from camera

[dzhou8]

Hi,

I have a question again.

I get the original depth image (16bit).

Can you tell me what is the relationship between the depth pixel and the real distance from camera??

Is there a proportional transformation? like (pixelValue/4096 = realDistance/65535) or other what?

And how can I get the relationship?

That's sooo important to me, thank you very much!

Hi Dan,

Thanks for contacting us! I have been looking for the information that I believe you may find useful, according to the https://software.intel.com/sites/default/files/managed/0c/ec/realsense-sr300-product-datasheet-rev-1-0.pdf Intel® RealSense™ Camera SR300 datasheet, the depth capture range is from 0.2 to 1.5m, also you can take a look at the "Depth and Infrared Data Formats". In addition to that, depending on the algorithm you use, the operating ranges change, as it is stated in the SDK R3 documentation: https://software.intel.com/sites/landingpage/realsense/camera-sdk/v2016r3/documentation/html/doc_advanced_module_range_specification.html Algorithm Operating Ranges. Moreover, I'd like to share this article: https://software.intel.com/en-us/articles/robotics-development-kit-r200-depth-data-interpretation Robotics Development Kit R200 Depth-Data Interpretation, there is mentioned that the default scale of an Intel RealSense SR300 camera is 1/32th of a millimeter. Let me know if this information helps. Regards,-Yermi A.
