Uploading a Hard Example Image Set

This API is used to upload a hard example image set. The name of the uploaded file is in the format of model_name-camera_name-index.jpg. If a file with the same name exists in the folder, the file will be overwritten. You can add a timestamp to model_name or camera_name to prevent the file from being overwritten. Note that the OBS file name can contain a maximum of 1,024 characters.
