Published in Nerd For Tech·Nov 21OCR Data Annotation Case StudyAs a very important research direction in the field of computer vision, OCR technology involves a variety of application fields. Nowadays, many products have appeared in various application fields, including card identification, ticket identification, structured text information in the video, text recognition in natural scenarios, etc. The OCR is to…Ocr2 min readOcr2 min read
Nov 14Polygon Annotation Case StudyPolygon Data Annotation There are many items in irregular shapes that 2D bounding boxes cannot accurately recognize. However, polygon data annotation can label curves and different angles, more accurately reflecting the real shape of the target. In the field of data annotation, the level of machine models depends on data accuracy. Therefore, the…Data Annotation Services2 min readData Annotation Services2 min read
Nov 92D Images Obstacle Labeling Case StudyIn the automatic driving scenario, the moving vehicle needs to analyze the position relationship with other vehicles in the current lane and make appropriate control decisions to avoid accidents. For example, if there is a vehicle in a close distance in front, or vehicles on both sides are trying to…Dataannotations2 min readDataannotations2 min read
Nov 3Road Guardrails Data Annotation Case StudyAn automatic driving system refers to the vehicle operating system in which the work performed by the driver is fully automated and highly centralized. To realize autonomous driving, three basic questions need to be solved: where the vehicle is going, where it is going, and how it is going. The…Data Annotation Services3 min readData Annotation Services3 min read

Scenarios That Do Not Need Annotation (1) No Objects That Need to be Annotated In normal road scenarios, when the lane line is completely invisible due to damage, or there is no line in the image, it is not…Data Labeling7 min readData Labeling7 min read
Oct 27Lane Annotation Case StudyWith the era of automatic driving coming, the application scenarios requiring lane recognition are becoming more and more extensive, and the corresponding lane recognition technology is becoming more and more important. The specific reasons are as follows: first, it covers a wide range of scenarios, and lane recognition exists in…Semantic Segmentation3 min readSemantic Segmentation3 min read
Oct 25What is a Chatbot and How It Works?The chatbot is an AI program that reproduces natural human conversations online. It relies on predefined scripts to provide real-time responses to user queries through text or voice-based messages. AI chatbots rely on natural language processing (NLP) to convert text into a format that machines can understand. They capture patterns…Computer Vision2 min readComputer Vision2 min read
Oct 21Continuous Frame 3D Point Cloud AnnotationThe Difference Between Image Data and Point Cloud Data First, the perspective is different. Image data is a two-dimensional representation of the real world, while a Point Cloud contains three-dimensional information( a coordinate system), which can be projected to a variety of views. Second, the data structure is different. Image data is regular, dense, and in order, while point…Sensor Fusion7 min readSensor Fusion7 min read
Oct 18Crosswalk Annotation Case StudyIn the early 20 century, the British people designed a kind of horizontal crossing on the street. When pedestrians cross the street, they can only walk on the crossing. Therefore, there appeared a series of eye-catching lines in the streets of the city, which looked like the white stripes on…Semantic Segmentation3 min readSemantic Segmentation3 min read
