Spatial Filter

 

The HLS003S processing pipeline includes a bilateral 

Spatial Filter

 that can be enabled to improve the 

range data noise, for instance to obtain smoother edges. 

 

Spatial Filter

 can be toggled in Helios Flex Settings -> Stream Params. 

Amplitude Gain 

The HLS003S allows digital gain to be added to the amplitude image (intensity image) by adjusting the 

Amplitude Gain

 feature. 

 

Amplitude Gain 

can be toggled in Helios Flex Settings -> Stream Params. 

Note

 

 

Amplitude Gain does not affect the depth measurement data. 

 

 

Pixel Formats 

Range Data 

Range data represent the depth image. These pixel formats below represent the radial distance 

between the target and the camera. The following pixel formats are available: 

Coord3D_ABCY16s 

4-channel point cloud XYZ + Intensity, 16 bits for each channel, signed output 

Coord3D_ABC16s 

3-channel point cloud XYZ, 16 bits for each channel, signed output 

Coord3D_C16 

Depth Map Z plane, 16 bits 

 

The range data pixel formats listed above represent points in the point cloud with each of the ABC 

values representing the XYZ coordinates of the object’s surface from which the light pulse has been 

reflected from. For distance value in mm, the user can query nodes under the Scan 3D control in order
