How Annotation Support Helped to Improve a Self-Driving Car Model?

Introduction Self-driving vehicles are designs that combine the forces, such as AI models, which are trained to understand the world in the same way that a human does, i.e. recognising roads, cars, pedestrians, traffic signs, etc. in real time. Highly labelled data sets are the main determinant in creating models that can be accurate. Here know how a poorly performing autonomous driving system turned into a safety, more reliable system through professional annotation services of Annotation Support. 1. The Challenge An autonomous vehicle company faced: What ails the fundamental dilemma? Improper and dissimilar data labelling of a previous outsourced company. 2. Project Goals Annotation Support allocated the following techniques: 3. Annotation Techniques Used by Annotation Support Bounding Boxes & Polygons – cars, trucks, buses, pedestrians and cyclists Semantic Segmentation – Pixel Level label of roads, sidewalks, curbs, lanes lines LiDAR 3D Point Cloud Annotation depth / distance – LiDAR labelling Keypoint Annotation – Wheel locations, headlight locations, locations of joints of pedestrians to make predictions of moving direction Occlusion & Truncation Labels -Marking the truncated or occluded objects of the detection training 4. Quality Control Measures 5. Results One quarter-year later, having been re-annotated, and the data set scaled up: 6. Learning Key Points Conclusion Annotation Support does not only deliver labeled data–clean, consistent, context-aware annotations were directly contributed to better results in the AI judgment. In autonomous driving, the quality of the data obtained about perception may mean the difference between a near miss and accidents. With high-quality annotations, the self-driving car model became safer, faster, and more reliable—bringing it one step closer to real-world deployment.

Top Annotation Techniques Used in Autonomous Vehicle Datasets

Autonomous vehicles rely heavily on high-quality annotated data to interpret the world around them. From understanding traffic signs to detecting pedestrians, the success of these vehicles hinges on the precision of data labelling. To train these systems effectively, several annotation techniques are used to handle the wide range of data types collected from cameras, LiDAR, radar, and other sensors. Below are the top annotation techniques commonly used in autonomous vehicle datasets: 1. 2D Bounding Boxes Purpose: To find out and place objects (like vehicles, pedestrians, road signs) in 2D square video. How it Works: In the camera images, box shaped figures encircle objects of interest in the form of rectangles. A label is placed on each box (e.g. car, bicycle, stop sign). Use Cases: 2. 3D Bounding boxes Purpose: To sense the space and the position of the objects in the 3D space. How it Works: In 3D point cloud dataset (typically LiDAR) cuboids are labelled to indicate a 3D object (depth, height, width, and rotation). Use Cases: 3. Semantic Segmentation Purpose: To label each pixel (2D) or point (3D) in a point cloud or image, to a class. How it Works: The pixels of an image are classified based on the object which they are attached to (e.g. road, sidewalk, walking person). Use Cases: 4. Instance Segmentation Purpose: To recognize individual objects and boundaries, even when it comes to objects belonging to the same class. How it Works: Intertwines object detection with a semantic segmentation model to mark every object instance in different manners. Use Cases: 5. Keypoint Annotation Purpose: Indicate certain important locations on items (e.g. at joints of people, corners of traffic signs). How it Works: Keypoints where used are tagged at the important parts of the body such as elbows, knees, wheels of a vehicle or head lamps among others. Use Cases: 6. Lane Annotation Purpose: To precisely identify and mark lanes and lane divisions during the process of driving. How it Works: In detected lanes in images, curves or lines are drawn on top of these lanes. Commonly lines are drawn on top of these lanes via polynomial fitting of curved roads. Use Cases: 7. Cuboid Annotation for Sensor Fusion Purpose: To combine 2D and 3D annotations to improve accuracy through several sensors (camera + LiDAR). How it Works: LiDAR 3D annotations are projected to obtain refinements on 2D camera images with multiple sensor inputs. Use Cases: 8. Polygon Annotation Purpose: To label the objects that have odd shapes and sharp edges. How it Works: The polygons will be a draw around the contours of the objects instead of the bounding boxes, a rectangle. Use Cases: 9. Trajectory Annotation Purpose: To trace the motion-trajectories of dynamic objects between frames. How it Works: The positions of objects are tagged throughout the period to comprehend the velocity, direction and motion in future. Use Cases: Conclusion Proper labelling is the mainframe of the development of autonomous vehicles. All the methods of annotations have their own use, either it is to identify a pedestrian in a crosswalk, or a drivable route in front. With the world moving towards completely autonomous industries, these methods of annotations keep getting more accurate, quicker and scalable with AI-aided tools and with the assistance of human-in-the-loop frameworks. It is not only the training of a car but actually the training of a machine to comprehend the complications of the real world in driving.

Which is better for Autonomous vehicle: LiDAR or Radar?

Comparing LiDAR and Radar in the context of self-driving cars, it can be noted that each of the options has its pros and cons, and, thus, the question of which of them is superior depends on the context, price factor, as well as the conditions in which the auto-mobile will have to function. Here’s a comparison of LiDAR and Radar based on key factors relevant to autonomous vehicles: 1. Accuracy and Resolution: LiDAR: Radar: 2. Weather and Environmental Conditions: LiDAR: Radar: 3. Cost: LiDAR: Radar: 4. Range: LiDAR: Radar: 5. Object Classification: LiDAR: Radar: 6. Real-Time Processing: LiDAR: Radar: 7. Safety and Redundancy: LiDAR: Radar: Conclusion: Which is better? LiDAR is better when the fine mapping of an area is required, or when the detection of objects in detail is necessary, in the conditions where usage of LiDAR is not hindered, such as using in urban areas with good weather conditions. This type is more accurate and is very essential in the systems that require the determination of the precise shape and location of objects. Radar works better at higher power, for fixed all weather applications, long range and applications that are not highly sensitive to cost. It is especially useful in measuring speed and movement and especially during conditions of low light or even when the car is traveling at high rates. The Future: Nowadays, the many Autonomous Vehicle makers are integrating LiDAR, Radar, and Cameras so that every type of system can provide its strengths to build robust AVs. This approach improves safety, augments the number of sensors and the overall perception which enablers the self-driving car to drive in various terrains and climate.
