SimActive’s Correlator 3D Enriched with Cloud Sharing and Reflectance Calibration

SimActive, the Canada-based leading developer of photogrammetry software, has announced the release of Correlator3D version 8.5. The new version allows users to share and visualize projects in the cloud. It also features new tools for the calibration and processing of multispectral imagery. Specifically, results can be exported to the cloud directly from the software interface, and shareable links are automatically created for online visualization. Moreover, calibrated reflectance panels and sun sensors can be used to produce reflectance maps, with multispectral bands perfectly registered. “Our software attracts a variety of clients, with a wide range of needs”, said Louis Simard, CTO...

A Commercial Drone Mapping Solution Using the Phantom 4 PPK

Previously, people had to invest more than 30,000 dollars to purchase professional mapping drones and place a large number of control points on the ground to get accurate, survey-grade maps. This situation continued until DJI released the Phantom 4 series of commercial drones with integrated GNSS antenna and high-definition gimbal cameras. This paper proposes a commercial drone mapping solution using the Phantom PPK to significantly reduce control points, and explains the workflow, testing methods and how the results support this level of drone mapping accuracy. (This article is brought to you by Hi-Target and was written by Richard Pan and... (read more)

Adding a New Level of Reality Capture to 3D Point Clouds

Global technology company Emesent has announced the release of the colourization functionality for its Hovermap Lidar scanner. The 3D point clouds from Hovermap can now be augmented with true colour, providing additional context for visualization and analysis. "We’re excited to announce this significant new feature for Emesent," said Emesent's CEO and co-founder Stefan Hrabar. "Colourization provides greater insights for our customers across many industries. This builds on the incredible 3D data that Hovermap produces to create rich, accurate digital twins and surveys.” The new colourization feature for Hovermap utilizes the latest rugged action camera – the GoPro Hero8. This modular approach... (read more)

Integrating UAV-based Lidar and Photogrammetry

Dense 3D Point Cloud Generation with Ultra-high Precision
Recent unmanned aerial vehicle (UAV or ‘drone’) platforms jointly collect imagery and Lidar data. Their combined evaluation potentially generates 3D point clouds at accuracies and resolutions of some millimetres, so far limited to terrestrial data capture. This article outlines a project that integrates photogrammetric bundle block adjustment with direct georeferencing of Lidar point clouds to improve the respective accuracy by an order of magnitude. Further benefits of combined processing result from adding Lidar range measurement to multi-view-stereo (MVS) image matching during the generation of high-precision dense 3D point clouds. The project was aimed at the area-covering monitoring of potential subsidence... (read more)

How 3D Scanning Rebuilds Crime Scenes for Courtrooms

Capturing Crucial Evidence to Aid Justice
Crime scene investigators with larger US metropolitan police departments and state patrols are increasingly deploying 3D laser scanners to tell detailed, data-based stories that will withstand public and legal scrutiny while bringing justice to victims. 3D laser scanning technology is being used to accurately depict the relational aspect of each piece of evidence so investigators can rebuild and reconstruct crime scenes. This is a powerful investigation tool, especially as legal systems grow more comfortable with high-tech evidence in courtrooms.  In this digital age, the use of 3D laser scanners is expanding the role of geospatial technology in crime scene investigations....

Accuracy Near, Far, Above or Under – How is FIG Working Week 2020 Contributing

The skills that engineering surveyors had to acquire in order to respond to the challenges of the construction world have made them capable, also, of fulfilling other challenges, several of which motivated by an awareness of the limitations of our planet. Engineering surveyors have learned that they need to push the equipment and techniques to its limits, while having recognized the necessity to integrate new techniques which can present more complete answers, without forgetting an important qualifier: accuracy. The instruments and methodologies have allowed for the surveying engineers to start working either very closely to the studied object, or, otherwise,... (read more)

Positioning the World for the Future

FIG Commission 5 focuses on meeting the highest level of accuracy for Positioning and Measurement. It provides the tools, techniques and procedures to educate and train surveying professionals everywhere. Appropriate methodology for data collection and processing are required to be successful in an era of global, integrated geospatial data. The body of work Commission 5 focuses on the science of measurement (instrumentation, methodology and guidelines). Its six WG’s focus on application of geodetic standards under ISO TC211 and TC176-SC6 to position within geometric and vertical reference frames using GNSS observations combined with multi-sensor systems to be as cost-effective as possible....

The FIG Standards Network and Standards in Surveying

A simple inspection of still-existing Roman roads, aqueducts and canals shows that the Romans were exceptionally skilled engineers. Shoe sizes provide a person’s shoe fitting size. There are many different shoe-size systems used in the world today. Wi-Fi is a family of wireless networking technologies, commonly used for local area networking of devices and Internet access. Wi-Fi and internet technologies are particularly important in the situation we find ourselves in today. But what do Roman roads, shoe sizes and Wi-Fi have to do with surveying and indeed FIG? Surprisingly they have a lot in common… What do Roman ruts have... (read more)
