Action assist: 2D / 3D fusion

in 2d/3d fusion tasks where you connect 3d boxes and 2d boxes, action assist provides recommendations in the 2d view it is most efficient to annotate an object in the 3d view first this provides a perfect prior for where the object is in all cameras at once sequence the first action assist recommendation will be the docid 8oxmj9rnuv9li 8vh1bdx automation pressing shift+space will run it quicker than pressing the button manually with a bounding box in each frame, action assist will now guide you through the sequence if the task contains 2d box prelabels, you will get the accept prediction option if there is a prelabel with a high overlap with the projected 3d box otherwise, it will only zoom to the location of the box in the next frame, eliminating the need to zoom to the next location single frame the single frame action assist for 2d / 3d fusion will guide you through the optimal workflow will annotating the 3d box first, then draw the object in 2d in each source that the 3d box is visible in next prediction in 3d you will be guided to the next prelabel in the 3d scene if it's a false positive you can simple press 'backspace' to ignore it and press shift+space to go to the next one select class selecting a class with a prelabel selected will create an object at it's location if there is no prelabel for a given object draw it manually go to 2d while you have the context for the current object we encourage you to finish annotating 2d before drawing the next object in 3d draw connected 2d box you will be zoomed to the location of the projection of the 3d box, and the drawing tool for docid\ tfjsznromwyazm4 smr5c will activate if the object is fully occluded press shift+space again to skip this source this step will be repeated for each camera source the object is visible in go back to 3d this action will deselect the current object and go back to 3d going back to step 1 now putting it all together we get the workflow illustrated below related content docid\ jw2jfj5i04upvcc7hv3ek docid\ tfjsznromwyazm4 smr5c docid\ sbxa8ffxzbll 5fwq7qnl docid 8oxmj9rnuv9li 8vh1bdx
