The Other Photogrammetry Automation – Coded Targets

Photogrammetry Coded Target Examples

What are Coded Targets? Automation History Why Use Coded Targets? Coded Targets vs Smart Points Coded Target Examples and Applications What are Coded Targets? I am sure you’ve seen a bar code on product packaging. Bar codes are scanned by a laser that reads the pattern of white and black bars, and converts that into a unique number or ‘code’. The code can be used to identify the product at checkout. PhotoModeler’s Coded Targets are like bar codes, in that they uniquely identify something (in this case a point on an object or in a scene), but have three differences: the code is printed in a circle, making it easier to identify at all angles (including a slant), the code…Read More


How to Digitize Templates and Patterns With a Camera

Posted on Thursday, August 3rd, 2017

In a number of industries measurements are made of objects and equipment in the field, and then materials are manufactured to fit those existing objects. Some common industries like this are kitchen counter tops, boat covers, enclosures, or flooring, wall cladding, and stairway coverings or lifts. A common approach within these industries is to create a template on-site from paper, cardboard, or plastic to form the fit of the final materials. The templates are returned to the manufacturer, and are used to form or cut the material (such as a kitchen marble counter top, or a boat cover), and the finish product returned to the customer or site for installation.  Accuracy of the cut and formed materials is key to…Read More


With a Camera Perform Non-Contact Industrial Measurement

Posted on Tuesday, June 27th, 2017

Today’s industries demand accurate and reliable measurements. Sometimes it can be expensive, time consuming or difficult to achieve the required precision using traditional measurement methods. For most design and fabrication processes, the margin of error is small, and inaccurate measurements can result in losses. Photogrammetry enables industries to obtain accurate and reliable measurements from images in good time and at reasonable cost. Traditionally we have thought about photogrammetry as being from the air – how most of our maps are created. Aerial photogrammetry entails using photographic images captured from airborne platforms while terrestrial photogrammetry utilizes photographs captured from the ground. In addition, close-range photogrammetry refers to a process where the camera is ‘close’ to the object being measured. Industrial uses…Read More


Capturing Motion with Photogrammetry and PhotoModeler

Posted on Friday, October 11th, 2013

In this post I highlight the practical uses of PhotoModeler Motion (PMM), and feature two example projects. PhotoModeler Motion / PMM is the top of the PhotoModeler product line. It brings the time dimension into your measurement and modeling projects. PMM includes all features of PhotoModeler and PhotoModeler Scanner, and adds modeling of a dynamic object or scene over time – a PMM project encapsulates a series of mini projects – one per ‘epoch’, based on the frame rate of your photography or video. Some uses of PMM are a) measuring the effect of a load on a material over time, b) modeling the change in shape of an object or scene due to erosion or human action, or c)…Read More


Tip 25: Automating coordinate systems in PhotoModeler Coded Target Projects

Posted on Monday, November 12th, 2012

In this tip video we show how Coded Targets can be used to automate the definition of scale, translation, rotation and offsets in PhotoModeler. This is useful in a couple of scenarios: 1) When you have a type of project you repeat often, it might be useful to have its scale (and coordinate system rotation) set up automatically during the target marking stage. Less manual work to do. 2) When you have a set of pre-made targets (as shown in the video) attached to a scale bar, an L-shape (for rotation system definition), or paired offset targets. Then whenever you place the scale bar (or L-shape or offset targets) with coded targets in your scene and use the automated project…Read More
