Creating Geospatial Content with Photogrammetry Software

Over the last decade, the unprecedented population growth rates throughout much of the world and the subsequent need for information to support and manage that growth has put more pressure than ever before on geographical information system (GIS) and production mapping professionals. Businesses and planners need more up-to-date information than ever before, so much so that photogrammetry production “factories” can work 24/7 and still find it a challenge to keep up with the increasing volume of work.

Infrared Night Vision Expands What Drivers Can “See”

The U.S. military has employed infrared vision technology for years. But it has only been the past several years that thermal imaging, or infrared, technology has been made commonly available by automakers. With the introduction of Night Vision on the 2000 Cadillac DeVille, General Motors (GM) became the first automaker to bring the safety benefits of extended night vision to drivers. Today, Night Vision is available on Cadillac’s current models.

Handheld 3D Laser Camera

Creaform, Quebec, Canada, offers the Handyscan 3D self-positioning, handheld 3D laser camera that allows for real-time 3D rendering visualization of scanned data. Resulting STL files can be exported directly in any post-treatment software such as CAD, CAE, or CAM. Contact-free scanning is performed by sweeping over a part the laser light emitted by the camera.

GigE CCD Vision Camera

The GE680 CCD vision camera from Prosilica, Vancouver, Canada, runs 200-plus frames per second at VGA resolution and up to 1,500 frames per second when using a 25 × 25 region of interest. The camera’s Gigabit Ethernet interface is capable of sustained data rates of 125 MB/second, and it operates over standard Cat5e Ethernet cable at lengths to 100 meters. Longer distances are possible using Gigabit Ethernet switches or fiber optics.

Thermography Camera

The VarioCAM® thermography camera from JENOPTIK Laser, Jena, Germany, features an image resolution up to 1.2 megapixels and is designed for applications in scientific and industrial research and development. The camera is based on Resolution-Enhancement-Technology, an optomechanical procedure in which the resolution of the 640 × 480-pixel microbolometer detector is quadrupled during the image saving process. In this way, the camera supplies thermal images with quality almost equal to photographs.

High-Definition Robotic Camera

Sony Electronics, Park Ridge, NJ, has introduced the EVI-HD1 high-definition EVI robotic camera, a single-chip-based, pan/tilt/zoom camera with multi-format capabilities to output both standard and high-definition video. The camera uses a 1080i CMOS sensor that delivers high-definition resolution in 720p, 1080i, or 1080p. The camera can be used with compatible codecs and systems from other manufacturers, due to its ability to output standard-definition video (YC and composite), high-definition analog component (Y, Pub, Pr), or digital HD-SDI.
