6.9. Depth Information Acquisition Flow Details

Figure 6-6 shows the mechanical status for the camera application (camera app) when
acquiring depth information. You need to perform the following five steps to acquire depth
information.
(1) Set the camera mode to depth-only.
(2) The preview starts after step (1).
(3) Depth information acquisition starts after step (2).
(4) Register the depth callback method at the optimal time.
The camera app sets the camera mode, resolution,
status.
Just after the preview starts, depth information acquisition is stopped.
information acquisition (startDepthStreaming)
status. The depth information acquisition can be used when the camera is in the mode that
can receive depth information. (In EDof mode or depth-only mode)
If the camera is in a mode that cannot acquire depth information (side by side or
single-through), an exception is generated. If
during depth information acquisition, then this can be processed based on the depth
information in the callback function. For registering depth callback, use the onDepthMap API
for setDepthCallback and processing depth information.
When returning to a depth information acquisition stop status, you will need to stop the depth
information acquisition (stopDepthStreaming). When stopping a preview during the depth
information acquisition, the depth information acquisition will be processed at the same time.
