Photogrammetry System

Photogrammetry System


A brief introduction to Photogrammetry System is given to those who are unfamiliar with the technology.

The fundamental principle used by Photogrammetry System is triangulation. By taking photographs in at least two different places, it is possible to develop "sight lines" of each camera at the points of the object. These lines of sight (sometimes called rays because of their optical nature) are cut mathematically to produce three-dimensional coordinates of interesting points. Triangulation is also the principle that is used by theodolites for coordinated measurements. If you know these instruments, you will find many similarities (and some differences) between photogrammetry and theodolites. Even closer to home, triangulation is also the way in which your two eyes work together to estimate the distance (perception of depth).
Photogrammetry System

This primer is divided into two parts. The photograph describes the photographic principles involved in Photogrammetry System, while metrology describes the techniques for producing three-dimensional coordinates of two-dimensional photographs.

To perform photogrammetric measurements, the object must be recorded from different directions with a high-quality digital camera. There is no need to preserve the exact position of the camera. Some coded measurement markers are applied to the device or directly to the object and are used for the automatic evaluation process. The scale bars are placed next to the object. Their dimensions are transferred to the measurement to provide a scale and to observe the accuracy of the measurement. The surface points to be measured must be marked with markings or removable adapters. The thicknesses of these markers are precisely known in the system. Another method is to score points or sections with a pen. Each drawn point or line is precisely defined by algorithms for image processing. The camera images are immediately transferred to the computer via a super fast wireless network or a flash card reader. From there, the computer performs dimensional analyzes and evaluations.

2D Drawing Creation Services

2D Drawing Creation There are two types of computer-aided design systems used for the production of technical drawings " two dimensions (" 2D ") and three dimensions ("3D"). 2Ddrawing creation services such as AutoCAD or Micro Station replace the paper drawing discipline. AutoCAD is a computer-aided drafting software program used to create blueprints for buildings, bridges, and computer chips, among other things. Discover how AutoCAD is used by drafters and other professionals. 2D technical drawing is the act and discipline of composing drawings to a precise scale that visually communicate how something functions or is to be constructed. It’s a rare engineering project that doesn't use 2D drawingscreation services in some form. Sketch pads, for instance, are time-honored places for first ideas. Drawings are the final deliverable for many engineering processes—they represent a contract between design and manufacturing—which means tha...

CMM ( Coordinate Measuring Machine )

Image
Coordinate Measuring Machine A Coordinate Measuring Instrument (CMM) is a device that measures the geometry of physical objects by detecting discrete points on the surface of the object with a probe. Different types of probes are used in CMMs, including mechanical, optical, laser and white light. Depending on the machine, the position of the probe can be manually controlled by an operator or computer. CMM inspection services generally specify the position of a probe in terms of displacement relative to a reference position in a Cartesian coordinate system in three dimensions (i.e. with the XYZ axes). In addition to moving the probe along the X, Y and Z axes, many machines also control the angle of the probe to measure otherwise inaccessible surface.  CMM Inspection Services Specifications Although all CMM inspection services perform the same functions, each machine type is built and designed differently. When selecting a CMM, an industrial purchaser must ...

3D Scanning Services

Image
With 3D scanning Services you can create and use data that can be used in the production process, so that you can measure parts, create CAD data, adjust parts, improve quality and more. 3D scanning Services is usually the first step in complex parts of reverse engineering. The main purpose of reverse engineering is to make a 3D CAD model for use in the customer's CAD system. The point clouds can then be triangulated in a polygonal net, or STL file, which can then be suitable for 3D printing, reverse engineering and / or quality control. High quality 3D scanner (Blue Light Scanner) The services offered are displayed using modern technology, under the supervision of qualified personnel. This scanning is fast and a full scan with internal and external details can be done in one scan. 3d Blue Light Scanner 3D scanning services for reverse engineering, quality control, design, prototyping, digital recovery, digital archiving, visualization, analysis and duplication. 3...
