I wrote a simple android app that streams the current pose estimate of arcore to draw a path, but now I have a problem: since the World Coordinate Space of arcore changes frequently I observe sudden jumps in the path (sometimes 10cm and sometimes up to 1.2m).\r\nIs there a way to get the pose with reference to a fixed coordinate space or maybe to know when and how it changes, in order to correct the \"jump\"?\r\n\r\nThank you in advance"},"comment":{"url":"https://api.github.com/repos/google-ar/arcore-android-sdk/issues/comments/441652343","html_url":"https://github.com/google-ar/arcore-android-sdk/issues/572#issuecomment-441652343","issue_url":"https://api.github.com/repos/google-ar/arcore-android-sdk/issues/572","id":441652343,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0MTY1MjM0Mw==","user":{"login":"manuelloit","id":38975832,"node_id":"MDQ6VXNlcjM4OTc1ODMy","avatar_url":"https://avatars3.githubusercontent.com/u/38975832?v=4","gravatar_id":"","url":"https://api.github.com/users/manuelloit","html_url":"https://github.com/manuelloit","followers_url":"https://api.github.com/users/manuelloit/followers","following_url":"https://api.github.com/users/manuelloit/following{/other_user}","gists_url":"https://api.github.com/users/manuelloit/gists{/gist_id}","starred_url":"https://api.github.com/users/manuelloit/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/manuelloit/subscriptions","organizations_url":"https://api.github.com/users/manuelloit/orgs","repos_url":"https://api.github.com/users/manuelloit/repos","events_url":"https://api.github.com/users/manuelloit/events{/privacy}","received_events_url":"https://api.github.com/users/manuelloit/received_events","type":"User","site_admin":false},"created_at":"2018-11-26T14:13:41Z","updated_at":"2018-11-26T14:13:41Z","author_association":"NONE","body":"I'd need it too; it would be really a very important thing"}}
