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：Paper link: https://arxiv.org/pdf/2401.13172.pdf Code link: https://github.com/hht1996ok/ADMap Abstract This article introduces ADMap, a method for reconstructing online vectorized high-precision maps Anti-interference framework. In the field of autonomous driving, online reconstruction of high-precision maps is crucial for planning tasks. In recent years, a variety of high-performance high-precision map reconstruction models have been developed to meet this demand. However, due to prediction bias, the point sequence within the instance vector may appear jittered or jagged, which will affect subsequent tasks. To this end, this paper proposes an anti-interference map reconstruction framework ADMap. ADM

Article Introduction：Written above & the author’s personal understanding is that I am very happy to be invited to participate in the Heart of Autonomous Driving event. We will share the anti-disturbance method ADMap for online reconstruction of vectorized high-precision maps. You can find our code at https://github.com/hht1996ok/ADMap. Thank you all for your attention and support. In the field of autonomous driving, online high-definition map reconstruction is of great significance for planning and prediction tasks, and recent work has built many high-performance high-definition map reconstruction models to meet this need. However, the point order within the vectorized instance may be jittered or jagged due to prediction deviations, thus affecting subsequent tasks. Therefore, we propose Anti-DisturbanceMaprecon

Article Introduction：Can you use raster data to crop vector data in arcgis? Two methods for raster cropping 1. In ArcToolBox, click "Data Management Tools - Raster - Raster Processing - Cropping" to open the interface as shown in Figure 1. . In the interface, there are two important options to pay attention to: "Input Raster" and "Output Range". First, select the raster data you want to clip in the "Input Raster" box. This can be any raster layer that needs to be clipped. Next, for the Output Range option, you can select the vector boundaries for clipping. This option determines the extent of the raster data after clipping. Here, something to pay special attention to is the option "Use input features for clipping". If this option is unchecked, the cropped range will be outside the vector bounds.
