The purpose of this study was to compare the accuracy and precision between the Reverse Projection and PhotoModeler methods for suspect height analysis. Thirty analysts were assigned to measure the heights of three different suspects, one for each method, with the suspects having been recorded standing at three different distances in a scene. Reverse Projection yielded a greater range of error and tended to have higher standard deviations than PhotoModeler, but the overall accuracy between the two methods was found to be comparable. The majority of absolute measurement errors for both methods were less than 2 cm.

The purpose of this study was to examine how camera resolution and suspect-camera distance affect the accuracy and precision of suspect height estimations using PhotoModeler software. Interaction plots demonstrated little difference in errors for most resolutions and positions. The accuracy and precision of height estimates began to decrease with resolutions under 960H and distances over 36.5 m.

“In this interview, we talk to Jean Sans of Experts-Yachts about the uses of photogrammetry in maritime surveys. An early adopter of the technology, Jean has been employing photogrammetry in his practice since 1983.”

Body mass dynamics of animals can indicate critical associations between extrinsic factors and population vital rates. Photogrammetry can be used to estimate mass of individuals in species whose life histories make it logistically difficult to obtain direct body mass measurements.

Renewable energy, aside from the environmental benefits, is increasingly making economic sense. Wave energy is a viable form of renewable energy. In small-scale testing of wave energy converters (WEC), a key focus is on characterising the relationship between the primary converter and simulated power take-off system. If primary conversion is via the deformation of a flexible material, this task often requires non-contact measurement. In this paper, the authors introduce the development of an underwater non-contact measurement technique called videogrammetry, and its novel application to characterise the primary converter operation of a flexible membrane WEC.

Mr. Mayda, a long-time user of PhotoModeler, explains how photogrammetry, and animation based on that photogrammetric modeling, is being used in forensics.

A construction company based in North Carolina incorporates new drone photo technology with advanced software to calculate stockpile volumes quickly and efficiently, and in addition, create site topographic data.

Photogrammetry helps reduce the time to create marine enclosures and covers. Costa Marine Canvas specializes in producing high-end, custom marine furniture, soft goods, enclosures, and covers. One of the most difficult of those tasks is creating windscreen enclosures for large and complex fly-bridge structures. A typical flybridge enclosure might have five 5-foot tall panels, ranging in various lengths, and combined to be 20 feet or more. While basic in appearance, each panel consists of 20 or more complex pieces of various materials fastened together by adhesives and sewing to fit and fasten to the bridge structure.

PhotoModeler can solve important information about the single camera and the scene at the time of the crime, by using the image captured at the time of the crime, and combining that with 3D data captured after the crime.

In this paper a detailed method is described using PhotoModeler to ‘marry’ the detail of a 3D laser scan with one still from a security camera, and then exported to 3D Studio Max for further analysis.

The purpose of this project was to assess the feasibility to restore the Ely Bridge in Monticello, Iowa, a structure listed in the National Register of Historic Places. The author was invited by the Department of Civil Engineering of the University of Colorado, Denver, to create a three-dimensional scaled wire frame of the bridge to be used in a finite-element stress analysis. This report describes the effort of creating this digital three-dimensional wire frame, using photogrammetric tools. This
