- Q1
There are two sets of accuracy requirements - one for the system detected cuboids, and one for the cuboids that the annotators fix manually. Identify which set should be for manually fix cuboid.
If the annotators changes the Label or position of an object, adds a key frame, or adds a new cuboid - the object must be annotated perfectly throughout its life - from the first frame to the last.
There should be no more than 20cm of space between the cuboid border and the closest point on the object.
There is no need to add missing cuboids or extend the life of existing cuboids to frames where there are less than this amount of LiDAR points.
Inaccuracies of up to 10% are within the tolerance, and such cuboids will be considered accurate.

30s - Q3
For pre-labeled cuboids, there is no need to fix cuboids that have minor inaccuracies.
truefalseTrue or False30s - Q4
If a cuboid is too large for an object, there is no need to fix it, as long as the empty part of the cuboid consists of 10% or less of the entire cuboid size.
truefalseTrue or False30s - Q5
Vehicle's side mirrors should be excluded in the cuboid. Pedestrian's limbs or held extremities should also be excluded in the cuboid.
falsetrueTrue or False30s - Q6
Very small items that project off the object (such as ribbons coming off a 'just married' car for example) should be left out if they will decrease the “tightness”/accuracy of the cuboid.
truefalseTrue or False30s - Q7
Some dynamic objects may have drift points (ECHO) on the front or back of the object in some frames. Do not let this drift points effect the cuboid - the drift points should be left outside. In frames with ECHO points please change the relevant 'ECHO points' value to 'NO'
