Our customers run these types of jobs to train computer vision algorithms to detect and track objects in 3D Point Cloud(LiDAR) scenes. It's a scene that was scanned and stead of a usual camera, its done with a laser beam and the resulta that we get as a cloud of points, the reason of the name. LiDAR means Light Detection and Ranging, but that's not crucial to understand the tool usage.
To better understand it imagine you were trying to build a self driving car or a robot to help keep factory workers safe - it would be really important to understand what type of objects are out there, where they are located and how objects move.
In order to make these algorithms successful they need lots of human labeled examples to show the computer and teach(aka“train”) it what to do
Customers will tell you what they are trying to understand and track in this Lidar/3D Point Cloud scene by using an“Ontology” - this is just a list of things(called“classes”) that they want you to label in the image
Our tool uses uses machine intelligence to help you use your human intelligence to build intelligence - How cool is this?! .

Some vocabulary before start
3D Point Cloud Annotation Tool
This is the tool you’re looking at now.
3D Point Cloud
A point cloud is a set of data points in space.
Interpolation
This is an algorithm that can predict the route of different objects from frame to frame.
Ontology
This is the list of items to annotate in the image. It’s on the left and can be short(1 class) or long(1000 classes)
Class
A class is a single type of object in the ontology to be annotated. This could be“car”,“pedestrian” or“dog”
Frame
A single scene from the sequence of scenes
Annotate
A fancy word for drawing on an image - when you put a box around an object in an image, you“annotate” that object
Cuboid
The technical word for the shape you will use to annotate
Computer Vision Algorithm
The type of machine learning(code) that understand and processes 3D Point Cloud data
Occluded
This is another term for“hidden by something”. If a person steps behind a tree so you can’t see them, they are occluded by the tree.
Scrub
This means moving between the frames of a scene(back or forth)
The task:
Attention: To achieve an optimal use of the tool we suggest using it on full screen and with a mouse. You can do it using a trackpad, but it can be harder.
