# Detection3DSettingsBase – LumiScan VGR

Common base class for 3D detection settings. See [OBJECT_FIT_METHOD](https://docs.hdvisionsystems.com/de/lumiscan-vgr-de/1.8.4/api/settings/detection-3d-settings-object-fit-method-ransac-cylinder-fit.html#detection-3d-settings-object-fit-method-ransac-cylinder-fit-object-fit-method) for specific detectors.

## Member Functions

- **`virtual ~Detection3DSettingsBase()=default`:**

- **`virtual OBJECT_FIT_METHOD type() const =0`:** *JSON Type*: string +*Requirement*: Must be a OBJECT_FIT_METHOD. Type of the 3D object detection.

## Member Variables

- **`maxNumObjects`:** `std::optional< int >`, default: `{100}` *JSON Type*: (optional) int UNIMPLEMENTED +*Requirement*: Must be greater than zero. Maximum number of objects that should be computed in the 3D detection pipeline.

[[-2]] `roiPercentage`:: `float`, default: `\{0.8f\}` *JSON Type*: float +*Requirement*: Must be greater than zero. Dilate 2D object detection results by this factor. The resulting area is used to determine all points that are considered for the geometric fit.

[[-3]] `minNumPoints`:: `int`, default: `{50}` *JSON Type*: (optional) int +*Requirement*: Must be greater than zero. Minimum number of points required for the geometric fit.
