Panorama Photogrammetry

Accurate 3D Documentation with High-resolution 360° Images

Under the leadership of the Japan Association of Surveyors, the new Fodis Measure3D system was benchmarked against total stations and single frame array cameras for detecting RFID tag positions. One test was performed outdoors for accuracy and two tests indoors for productivity. Fodis Measure3D proved to be an accurate and reliable solution and was shown to be time-efficient, especially for indoor applications where rapid, accurate and selective point measurements are required. In Japan, outdoor navigation by GPS is both popular and successful, and such outdoor navigation technology is now available for use with smartphones - to provide an online... (read more)

Helicopter Photogrammetry

Safe, Accurate and Cheap Mapping of Transportation Corridors

Surveyors working on busy roads are constantly subjected to close misses from passing traffic; it can be worse. Helicopter photogrammetry is a survey technique designed to prevent fatalities. A complete, dated record of the project area can be economically delivered and accessed at will without having to revisit a dangerous survey site. The authors describe this solution. Terrestrial surveying on fast-moving transportation corridors often means lane closures and roadside work zones but despite these precautions they still remain dangerous places to work in. Traffic management is very expensive and can have a severe impact on the project budget. Lane closures... (read more)

Layman's Photogrammetry

Taking images is the fastest and most reliable way to capture reality. Thirty years ago photogrammetrists dreamed of loading aerial images into a computer and within minutes retrieving - without human intervention - a fully detailed map. Soon, however, the multifaceted nature of image content became evident, and visual interpretation, so easy for human beings, proved too complex for transfer into computer algorithms. The dream evaporated. To date, commercial digital photogrammetric workstations (DPW) support at best semi-automatic extraction of points, lines (mostly roads) and objects (mostly buildings). A human operator approximately locates and identifies a feature, and then comes edge... (read more)

Parallel Computing in Photogrammetry

Seamless Orthomosaic Creation from Massive Imagery

The race between data production and processing capacity has been going on for many decades, with data production usually on the winning team. This is also true for airborne and space-borne imagery, as the amount of images captured by satellite sensors and aerial cameras is growing not only steadily but also rapidly. How can the abundance of pixels be processed into photogrammetric products quickly and effectively? The answer lies in parallel computing. Today, computer clusters enable fast and affordable processing of photogrammetric tasks. Read on to learn how parallelism speeds up the creation of seamless orthomosaics. By Andrey Yu. Sechin, Racurs,... (read more)

Experiences in UAS Photogrammetry

Quality Matters

UAS mapping is widely accepted as a new method for acquiring spatial image data. The main business opportunities clearly lie in projects which are too small to be of interest for aircraft and helicopter platforms and too big for field mapping. Nevertheless, performing UAS operations profitably and with high-quality results is quite demanding. At the end of the day, the paying end customer is not really interested in whether the data was produced using UAS or more traditional methods; data quality is all that matters. This article focuses on UAS mapping productivity topics, shedding light on the practical challenges of... (read more)

Implementation ERDAS Photogrammetry Solutions

Department for Planning & Infrastructure (DPI), a government agency in Western Australia has selected several ERDAS photogrammetry solutions for analysing coastline movements, engineering, maritime facility mapping and nautical charting. DPI is implementing LPS, ERDAS' signature photogrammetry solution that integrates software tools to streamline production-mapping workflows. LPS will be used to capture coastline movement information from current aerial photography. Coastal engineers can use LPS to study areas of the coastline in 3D and make better informed decisions about potential coastline movement and infrastructure impacts. IMAGINE Autosync enables DPI to rectify old imagery to accurate present day aerial mosaics. Because older... (read more)
