Unify size and direction

unify size this feature takes the box size in the current frame and applies it to all frames (where the object is visible) we recommend using this feature when you have found the one frame where the cuboid is the most visible (has the most points) it will make the adjustment process more efficient select an object to enable the feature activate it by pressing the left toolbar button or using the assigned shortcut key unify direction this feature ensures that an object maintains the same heading across all frames where it is visible this is especially useful when you’ve annotated an object moving along a straight line or a stationary object, like a parked car, and later realize its orientation is inconsistent or incorrect it saves you time from manually adjusting each frame select an object to enable the feature activate it by going to the top bar, the right click menu or using the assigned shortcut key if unify direction is used on a moving object that is not moving in straight line the resulting direction may become incorrect align heading to trajectory this feature adjusts the object’s heading to match its movement direction throughout its trajectory this helps reduce box “wiggling”, keeps the heading consistent with how the object moves and reduces manual adjustments in each frame to activate the feature, right click on the object and select "align heading to trajectory" from the context menu this function is ideal for dynamic objects, such as vehicles or pedestrians in motion, but can produce incorrect headings if the object is fully or partially stationary
