Purpose¶

This is a reader for pairs of .837/.83B files created by Model 837 DeltaT Azimuth Drive Sonar System by the IMAGENEX TECHNOLOGY CORP.. To create a useful point cloud at the module outputPCLObject0, both files have to be provided next to each other.

Output points are of type XYZINormal which means that each point is a tupel (x, y z, w, nx, ny, nz, nw, intensity):

x / data[0]: the x-component of the point
y / data[1]: the y-component of the point
z / data[2]: the z-component of the point
w / data[3]: the homogeneous scale factor (usually 1)
x / data_n[0]: the x-component of the normal of the point (usually 0)
y / data_n[1]: the y-component of the normal of the point (usually 0)
z / data_n[2]: the z-component of the normal of the point (usually 0)
data_n[3]: the homogeneous scale w-component of the normal of the point (usually 0)
curvature: the curvature value of the point (usually 0)
intensity: the intensity value of the point (the magnitude value of the signal)

Thank you to Dr. Miriam Roemer for providing a draft reader and examples data for such files which were very useful to implement this module.

Output Fields¶

outputPCLObject0¶

name: outputPCLObject0, type: MLBase¶: Point cloud output in Cartesian coordinates(usually with PCL XYZINormals). This module still does not set up any indices in the output base object, which, however, may be added in the future.

outputPCLObject1¶

name: outputPCLObject1, type: MLBase¶: Point cloud output in raw index coordinates corresponding to the sonar scan order (usually with PCL XYZINormals). This module still does not set up any indices in the output base object, which, however, may be added in the future.
