2D bounding boxes

drawing tool this geometry shape is drawn using the bounding box tool the tool is used to mark the extreme points of objects such as vehicles, animals and pedestrians drawing process select a class place a point at the object's highest, lowest, rightmost, and leftmost point after placing the last point, a bounding box should appear drawing process with auto complete if we can predict a bounding box at the target location, it will appear when you mouse over the object if it is a bad prediction, you can simply press escape to hide and ignore it select a class hover the mouse over the target object, a prediction will appear press tab to quickly accept the prediction transformation controls translate (change position) press anywhere inside the box to move it to another place scale you can edit the size of the box by dragging one of the eight points available reference line some tasks ask you to mark a line on the bounding box — for example to indicate a horizon, a ground contact line, or a split between two regions of the object when a class is configured for this, the reference line tool becomes available, and the line you draw is stored as a property of the box a reference line always belongs to a bounding box and runs across the whole box, either vertically or horizontally the orientation is fixed by the task — you place the line, you do not choose its direction select the box you want to add the reference line to under property markings on the expanded object entry in the right side menu select reference line to activate the tool click inside the box to place the line to adjust it, drag the line along its axis a vertical line moves left and right, a horizontal line moves up and down the line stays within the box shortcuts enable the shortcut mode by pressing ctrl arrow up shift ctrl for mac when one side turns green, edit the side using the arrow keys switch side by holding ctrl and pressing the arrow keys the sides will by default move one pixel, hold shift to move it five pixels at a time related content create connected 2d box docid 8oxmj9rnuv9li 8vh1bdx 2d shape tracking docid\ x9kkl6lo8g7pyatb5nmla 2d machine assisted tools docid\ b1putylvp306oo0rsvotq
