Witryna28 cze 2024 · Object detection in point cloud data is one of the key components in computer vision systems, especially for autonomous driving applications. In this work, we present Voxel-FPN, a novel one-stage 3D object detector that utilizes raw data from LIDAR sensors only. The core framework consists of an encoder network and a … Witryna26 maj 2024 · The core idea is to use Gauss map. Gauss map is a crucial concept in classical differential geometry of surfaces. By definition, Gauss map sends each point on a surface to its unit normal vector. For an oriented point cloud, which we mean a point cloud with a given unit normal vector field, Gauss map is automatically defined.

Witryna1 mar 2016 · Point cloud pre-processing. Look for ways to break up the point cloud into chunks that can be processed more quickly. Parameterization. Once data is preprocessed, you can define narrower search bounds for your plane fit algorithm. For example, only try plane fits within a few degrees of vertical.
