As 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…

Polygon 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…

In 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…

An 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…

Label the Target Underline the lines in the image and label their attributes. Labeling Rules 1. 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…

With 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…

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…

The 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…

In 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…
