Data annotation is essential for improving the accuracy of automated driving techniques, with various methods like 3D cuboids, polygons, and semantic segmentation being utilized. Each method has its specific use case, such as determining object distance, identifying irregular shapes, and classifying objects within images. Overall, data annotation outsourcing services are crucial for the automotive industry to ensure precision and enhance user experience.

Data Annotation tools in automotive Industry
The efficacy in Machine Learning is dependent on many factors, among which is data
annotation solutions. Data Annotation Platform can aid in improving the accuracy of
automated driving techniques. Many image annotation kinds like polygon bounding boxes, 3D
cuboids, Semantic Segmentation, Lines and Splines can be integrated into machine learning
models. But the best method of Data Annotation Outsourcing services suitable for your project
must be selected based on the specifications of your particular project.
The most common types of Data Annotation tools:
3D Cuboids
It is like the bounding boxes mentioned earlier, where the annotator draws boxes around
objects of an image. But unlike the namesake, the bounding boxes used in this kind of data
annotation services are 3D that allows an object's label to be placed based on dimensions,
width and length (X Z, Y, and the axes).
This data annotation tool is essential in determining the distance between an object to the
vehicle by looking at the object's depth and detecting the size and location. The annotator
outlines to capture the object of importance and sets anchor points along the object's edges.
Suppose an edge is absent or blocked by an object. In that case, the annotator calculates
the edge's location determined by the object's characteristics and how the picture is
positioned.
Polygons
Sometimes dimensions and shapes of the objects make it difficult to draw bounding boxes
for certain items in an image. Polygons are a reliable method of detecting objects and
locations in video and images that contain irregular objects.
They are among the most frequently employed data annotation tools because of their
precision. Its accuracy is not without cost, as it takes longer to complete than other methods.
Shapes that are irregular like animals, humans, bikes, and even bicycles will require more
than a 2-D or 3D bounding box to be noted.
Polygonal annotation is an efficient data annotation tool for algorithms used in autonomous
vehicles because it allows the annotator to identify different aspects such as the edges of a
road or sidewalk and obstructions to objects, to name a few.

Healthcare has become one of the most challenging and demanding spheres, especially
after last year's coronavirus epidemic. Every effort is directed towards solving as many
problems as possible. In most cases, 30% of tasks can easily be automated.
Semantic Segmentation
We have examined the definition of the objects within an image; however, semantic
segmentation is better than the other methods. It is a method of associating each pixel of an
image to the class. The self-driving vehicle must comprehend its surroundings for it to
function in a real-world setting.
The method divides the objects into bicycles, cars, pedestrians, sidewalks, traffic lights, etc.
Most often, these are a list the annotator has. Semantic segmentation identifies and
classifies an object, identifies it and then divides it into segments to allow computer vision.
Medical imaging is one area that is seeing this method gain wide acceptance.
Splines and Lines
In addition to recognizing objects, there's also the need to train models to recognize the
boundaries and lanes. Annotators draw lines on the image to indicate edges and lanes to
assist in developing the model. These lines allow the car to detect or recognize the lanes,
which is a crucial requirement for autonomic driving to succeed because it allows the car to
move smoothly through traffic while also adhering to the rules of the lane and avoiding
accidents.
Conclusion:
The primary purpose of Data Annotation Outsourcing services in the automotive industry
is to categorize and segment objects within the form of video or images. They aid in
achieving accuracy, which for automotive is crucial, considering that the industry is a
mission-critical field, and the precision directly affects the users' experience. However,
they're not specifically designed to train models to autonomous vehicles. Different data
annotation tools are employed.
