NormalEstimation

NormalEstimation estimates local surface properties (surface normals and curvatures)at each 3D point.

Example​

TypeScript
await PCL.init();const tree = new PCL.SearchKdTree<PCL.PointXYZ>(PCL.PointXYZ);const normals = new PCL.PointCloud<PCL.Normal>(PCL.Normal);const normEst = new PCL.NormalEstimation();normEst.setSearchMethod(tree);normEst.setRadiusSearch(0.05);normEst.setInputCloud(cloudTarget);normEst.compute(normals);

Type Definitions​

NormalEstimation​

TypeScript
class NormalEstimation<PointInT extends XYZPointTypes, PointOutT extends Normal = Normal> extends Feature<PointInT, PointOutT> {    constructor();    setViewPoint(vpx: number, vpy: number, vpz: number): void;    getViewPoint(): {        vpx: number;        vpy: number;        vpz: number;    };    useSensorOriginAsViewPoint(): void;}

Feature​

TypeScript
class Feature<PointInT extends XYZPointTypes, PointOutT extends FPFHSignature33 | Normal = Normal> extends PCLBase<PointInT> {    constructor(native: NativeAPI);    setSearchSurface(cloud: PointCloud<PointInT>): void;    setSearchMethod(searchMethod: Search<PointInT>): void;    getSearchMethod(): Search<PointInT> | undefined;    getSearchParameter(): number;    setKSearch(k: number): void;    getKSearch(): number;    setRadiusSearch(radius: number): void;    getRadiusSearch(): any;    compute(cloud: PointCloud<PointOutT>): void;}

PCLBase​

TypeScript
class PCLBase<T extends PointTypes> {    manager: Manager;    constructor(_native: NativeAPI);    setInputCloud(cloud: PointCloud<T>): void;    getInputCloud(): PointCloud<T>;}
