Kinematic LiDAR Data Processing with RIEGL RiPROCESS 1.9.1 Software

Explore the Newest Features of RIEGL’s Software Suite and Benefit from the Increased Post-Processing User-Friendliness of RIEGL’s Kinematic Laser Scan Data.

Launched in May 2021, the newest version of RIEGL’s software suite for processing kinematic LiDAR data, RiPROCESS 1.9, has been available.

With this updated version, RIEGL users have the ability to view large amounts of data in RIEGL’s proprietary data base feature with compressed data storage, high level-of-detail, and other additional valuable point attributes. Key modules of the software suite have been re-designed to speed up data processing, saving time in the office.

A more flexible licensing scheme has been introduced, allowing for the dongle-free operation of all features based on licenses assigned to instrument serial numbers.

Additionally, further ongoing improvements have been made and with RiPROCESS 1.9.1, an extended and accelerated version presents even more features.

See below for a short introduction to the main updates and enhancements of the current software version of RiPROCESS:

Exponential Decomposition

A newly implemented full waveform processing algorithm, called exponential decomposition, was designed for, and is especially applicable, to analyzing waveforms from laser bathymetry, as it can perfectly model the distributed backscatter from the water column.

Additionally, for bathymetric laser scanning purposes, water surface models can now also be handled in an arbitrary map projection and stored in the GeoTIFF format for ease of use with 3rd-party software.

Advanced Image Correction

Especially designed for mobile laser scanning, the handling of images from the RIEGL cameras has been both extended and improved.

The optional Gamma Correction feature enhances the image processing tools for developing raw images. It allows for a non-linear correction of the image luminance to be adopted to fit that of the visual perception of the human eye. It can be used to lighten up shadowed areas of an image.

The export of the images to industry standard image format JPEG and TIFF is now massively accelerated by the use of graphic cards (GPU) processing. The export of images is now up to 15 times faster than previous versions!

For easy use of collected images in 3rd party applications, the removal of the distortions introduced by the camera lens is mandatory. With the introduction of a new algorithm for undistorting the images, the original image quality is now maintained.

Scan Alignment (SCAL) Tool

With the re-implementation of an updated Scan Alignment (SCAL) Tool, point cloud adjustment benefits from more control of selected mission-critical areas. The tool can be optionally applied after a standard scan data adjustment procedure to even further improve the data matching quality. With the SCAL tool, the user can guide data to locally match at selectable sites.
