Guide: Create your first annotation
One of our main goals with this user documentation is to get you started using our annotation platform and doing tasks. There are a lot of views, modes, and features to read about but let's get you started with the basics - creating annotations.
Well, it is what we use to produce annotated data. When a client orders annotated data from us we use a chain of tasks to produce that annotated data. For example, to annotate one image and the vehicles in it we might use multiple tasks:
- An Annotate task to annotate the data from scratch. The team member working on the task gets an empty image and gets to mark out the vehicles in it.
- A Correct task to find and fix any mistakes the first team member did.
- A Review task where the client can look at the annotated image and give feedback as well as ask for corrections of mistakes.
- A Review Correct task where the issues found in the review are corrected.
- Another Review task to review the corrected issues.
To find a task to work on you need to navigate to the page Introductionο»Ώ. On this page, you will find the tasks you have been assigned and can work on.
In the section Available tasks, you find all requests in which you have been assigned a task. In each card representing a request, you can see which type of tasks (annotate, correct, review) you have been assigned and open them when needed. So, if you are assigned tasks in Request A and Request B, you will see two cards in this section.
To learn the basics, we suggest you select a task with the action Annotate. So, find a request in which you have been assigned an Annotate task and click Start a task to open it. If you can't find an annotate task - you can try the steps below in any other task as well.
You will go into a task looking for specific objects, for example, vehicles, pedestrians, or signs. Exactly what you are supposed to annotate is something a guideline (Key conceptsο»Ώ) will tell you detailed information about.
So when you have entered a task, the first thing you should do is scan the image. In other words - look for objects to annotate. When you have found an object it is time to pick a class.
Picking a class happens in two ways:
- By choosing an option in the class list located in the right-side menu, or
- By using a shortcut (press the hotkey number that is next to the class name).
Depending on the type of task you have, you will have to use one of the different Task shapesο»Ώ. To make sure we keep it to the basics we will annotate using one of the 2D tools as an example here.
When using the 2D drawing tool in this example task we are supposed to place extreme points around the object. The extreme points should be placed on the highest, lowest, rightmost or leftmost point of the object.
Once you have placed all four points, a colored squared box should have appeared around your object.
In the right side menu, in what we call the object list (a list with all your created objects), you will be able to tell that the drawing you just made was added to the list as an object.
Underneath the object name, there are a bunch of options to choose from - these are the property values.
By looking at the object you just created - try and set a value under each property name. Use the guideline (Key conceptsο»Ώ) if you're not sure about the different property values.
Once a value has been chosen it will show up as a purple chip next to the property name. You can change the value by clicking on it.
When you have selected a value for each property you are done with the object.
...and just like that you should have successfully created your first annotation in our platform π₯³ To complete the full task you repeat steps 2-4 for each relevant object you find.
