The default depth distance range for the D435i camera depth map

I use a python program to align the depth map and RGB map of the D435i camera, I want to know what is the default detection range of the depth map? Another question is that when I use "depth_frame = 50*np.asanyarray(aligned_depth_frame.get_data())" to process the depth frame to get the depth map, I find that the depth map shows the general outline of the object better, but does this have any effect on the depth map range?

    How to change the detectable depth distance range of the D435i camera depth map using a python program？

    Hi, the minimum depth sensing distance of the D435i camera model will be around 0.1 meters / 10 cm.

     

    Below is an example of Python code for altering the minimum depth sensing distance with the Disparity Shift option.  As the Disparity Shift value is increased, minimum distance reduces but the maximum observable depth distance also reduces.  '100' is a good value to test with.

     

    device = rs.context().query_devices()[0]
    advnc_mode = rs.rs400_advanced_mode(device)
    depth_table_control_group = advnc_mode.get_depth_table()
    depth_table_control_group.disparityShift = 100
    advnc_mode.set_depth_table(depth_table_control_group)

     

    Using aligned data will not affect the depth range.
