Article Introduction：Written before: The author’s personal understanding is that constructing vectorized high-precision maps based on sensor data in real time is crucial for downstream tasks such as prediction and planning, and can effectively make up for the poor real-time performance of offline high-precision maps. With the development of deep learning, online vectorized high-precision map construction has gradually emerged, and representative works such as HDMapNet, MapTR, etc. have emerged one after another. However, existing online vectorized high-precision map construction methods lack exploration of the geometric properties of map elements (including the shape of elements, vertical, parallel and other geometric relationships). Geometric properties of vectorized high-precision maps Vectorized high-precision maps highly abstract the elements on the road and represent each map element as a two-dimensional point sequence. The design of urban roads has specific specifications, for example, pedestrian

Article Introduction：There is no doubt that JavaScript does not have multi-threading. It can only do one thing one thing, and then do the next thing after finishing one thing. If your js takes a relatively long time to complete If one thing happens, the browser will freeze for a period of time and will not respond to the user's operations. What can we do?
