Figure 1 – Accuracy Vs Precision Dart board. It can be seen that precision is all about the spread of the data. To obtain high precision all the measurements (or throws) must be grouped together. I have a friend who showed a photogrammetric 3D model of Iceland to a year-old woman who currently lacks the mobility to return to the country in which she grew up. For pure visualization of captured and stitched photogrammetric 3D models, the combination of photogrammetry and virtual reality can’t be beat.
Breakthroughs in both math and science evolved this sector of metrology into what is known as close-range photogrammetry. The combination of an ultra-mobile photogrammetric camera and the high-precision measurement capabilities of a coordinate measuring machine (CMM) sets this technology apart in a field all its own. Precision and accuracy estimation is an important index used to reflect the measurement performance and quality of a measurement system. To reveal the significance and connotations of the precision and accuracy estimation index of a close-range photogrammetry system, several common precision and accuracy estimation methods are : Kai-Feng Ma, Gui-Ping Huang, Hai-Jun Xu, Wei-Feng Wang.
Okay, this software isn’t technically free, but it’s free for educational use. This means that if you’re using it to learn about photogrammetry, that’s fine, but you can’t use it for commercial applications.. This is an exceptionally simple photogrammetry program. Photogrammetry uses methods from many disciplines, including optics and projective l image capturing and photogrammetric processing includes several well defined stages, which allow the generation of 2D or 3D digital models of the object as an end product. The data model on the right shows what type of information can go into and come out of photogrammetric methods.

Crossfield Department of Civil and Surveying Engineering, California State University, Fresno, Fresno, CA ABSTRACT: The basic structure of a precise photogrammetric geodetic positioning cost model is developed and described.
Input and intermediate variables are defined. and platforms and associates them to different applications of photogrammetry. Photogrammetric Products The photogrammetric products fall into three categories: photographic products, com-putational results, and maps.
Photographic Products Photographic products are derivatives of single photographs or composites of overlap-ping photographs. 3D scanning by means of photogrammetry is exciting. Check out our guide to the best photogrammetry software available right now.

survey data is combined with field survey data to produce high precision mapping and meet the accuracy standards described in this Chapter. Aerial Photogrammetry Aerial photogrammetry is the science of deducing the physical dimensions of objects on or above the surface of the Earth from measurements on aerial photographs of the Size: 1MB.
Digital photogrammetric systems employ sophisticated software to automate the tasks associated with conventional photogrammetry, thereby minimizing the extent of manual interaction required to perform photogrammetric operations.
LPS Project Manager (Figure 3), which is part of the Leica Photogrammetry Suite, is such a photogrammetric system. Fig. A–C shows an example of how a high-resolution photogrammetric model can be nested within a much larger-scale multibeam sonar-derived bathymetry, highlighting how optical and acoustic techniques can work effectively in synergy.
These examples show the diversity of applications for nondiving-based benthic photogrammetric survey. We are currently developing a photogrammetric system    that performs high-precision measurements of 3D coordinates of control points on various objects.

With B. Wu, H. Hu, Author: B. Wu, H. Hu, W. Liu. In Part 1 I looked at the accuracy that photogrammetry was capable of in real-life situations. In Part 2 I looked at how you can predict the accuracy that will be achieved for a given project, taking into account the working distance, the camera and lens combination, and the geometry of the camera setups.
In Part 3 I’ll look at how much effort is required to achieve a given level of accuracy. Photogrammetric Images; Photogrammetric Record Cumulative Index; Virtual Issues.

AliceVision is a Photogrammetric Computer Vision framework for 3D Reconstruction and Camera Tracking. The unmanned aerial vehicle (UAV) photogrammetric survey of an archaeological site has proved itself to be particularly efficient.
In order to obtain highly accurate and reliable results, it is necessary to design carefully the flight plan and the geo-referencing, while also evaluating the indicators of the accuracy rate.
