Getting tracking results

To start receiving tracking results it is important to make sure the server is started (required only once at the start or after PSTapi/Pause has been called in the meantime). Explicitly setting the right exposure and activating the required target helps limit the chance of missed detections.

A typical call sequence in Curl

  curl --header "Content-Type: application/json" --request POST --data "{}" http://localhost:7278/PSTapi/Start
  curl -X GET http://localhost:7278/PSTapi/GetTargetList
  curl --header "Content-Type: application/json" --request POST --data "{\"TargetStatus\":{\"name\":\"target_main\",\"status\":true}}" http://localhost:7278/PSTapi/SetTargetStatus
  curl --header "Content-Type: application/json" --request POST --data "{\"Framerate\":30}" http://localhost:7278/PSTapi/SetFramerate
  curl -X GET http://localhost:7278/PSTapi/GetExposureRange
  curl --header "Content-Type: application/json" --request POST --data "{\"Exposure\":0.0001189}" http://localhost:7278/PSTapi/SetExposure
  curl -X GET http://localhost:7278/PSTapi/StartTrackerDataStream
Note
On line 3, change the name of the target "target_main" to a target name present in the target list.
If no objects are detected, try increasing the exposure setting on line 6.
When too many streams are opened at the same time, PSTapi/StartTrackerDataStream returns a 429 too_many_requests status code. More information on how to handle this error can be found in the PSTapi/CloseDataStream documentation.
