To get a better visual experience, you can turn off the Debug information to more intuitively view the positioning visual effect of the annotation content.

Status judgment description:

You can judge the current positioning status through the following three key indicators:

• Annotation cube status: It shows the white MEGA texture when the positioning is normal, and shows gray when the positioning fails.
• Parameters in the Debug information return box:
  • status status value: It shows the current positioning status.
  • Sequence parameter: N means not loaded, F means positioning failed, and S means positioning succeeded.
  • Status button: Green means the positioning succeeded, and white means the positioning failed.

The mini-program will display the status according to the return information of the service to help you understand the running situation of the positioning service:

• Positioning succeeded status: If you are at the on-site location, the positioning debugging information shows the text prompt status: Found, the Status button shows green, the Sequence parameter shows S, and the calibrated cube normally shows the white MEGA texture, indicating that the positioning service has successfully located the target.

  

• Concurrent alarm: If the positioning debugging information shows the text prompt status: QpsLimitExceeded, the Status button shows white, and the Sequence parameter shows F, it means that the positioning service is running normally, but the current QPS exceeds the limit. To solve this problem, please refer to Positioning Service Capacity Limit and Expansion.

  

• Target not found status: If you are not at the on-site location or there is no matching scene in the positioning library, the positioning debugging information will show status: Not Found, the Status button will show white, and the Sequence parameter will show F, indicating that the positioning service is running normally but fails to locate the target.

  

• Positioning service is abnormal: The positioning debugging information shows the text prompt UnKnownError, indicating that the positioning service is running abnormally. Please turn on Record Log and Record Data to record the error information and contact EasyAR customer service.
