What is the difference between the RDI Acquisition Software, the RDI Motion Amplification® Software, the RDI Motion Explorer Software, the RDI Motion Studio Software and the Motion Monitor Software?
These four software applications, used in conjunction with the video camera, make up the IRIS M™ System.
Your Iris M™ Acquisition System is delivered with a USB Memory Stick with an RDI Technologies™ logo. On that stick you will find the licenses issued with your system. The same files have been copied to the "Downloads" folder on the Acquisition System. They will typically be identified by your company name and may also include a contact name from your company. The file will be in a Text format. See the "Typical Files on USB Stick" figure below.
Typical Files on USB Stick:
After you open the text file, you will see that there are two licenses delivered with your Iris M Acquisition System. ("Typical License File" figure below.) The first, which is preinstalled in the system before delivery, is the "Full" or "Acquisition System" license which will activate the RDI Acquisition, Motion Amplification®, Motion Studio and Motion Explorer software. (For the difference between these see this article: RDI Technologies™ Acquisition Software vs. RDI Motion Amplification® Software vs. RDI Motion Explorer Software vs. RDI Motion Studio Software vs. Motion Monitor Software) This license is already active when you receive your system. You should see the four different icons associated with the RDI Acquisition, Motion Amplification®, Motion Studio and Motion Explorer software on your desktop when you first boot up the system.
Typical License File:
The second license will be identified as "SA" or Stand Alone or "Analysis Only". These three labels are all the same. This license is used to activate the Motion Amplification®, Motion Studio, and Motion Explorer software on a second analysis computer. When prompted, enter the license information into the license screen and select "Activate a license or renewal" as shown in the figure below.
License Activation Window:
Two different installations are possible:
The Acquisition Device in the Iris M System will come preloaded and licensed with the RDI Acquisition, Motion Amplification®, Motion Studio and Motion Explorer Software.
There is a second Motion Amplification® license on the USB memory device shipped with your kit. You may install a second bundle of Motion Amplification®, Motion Studio and Motion Explorer programs on a separate computer.
There is no specific maximum length of recording. It will depend on the available free Hard Disc space on the Acquisition Device. Keep in mind that processing time increases at a faster rate than recording time.
For Video Acquisition - Because you need the USB ports, using the Surface Book as a tablet takes a little creativity. But, if you detach the tablet from the keyboard, turn it around, reattach it, and close it up - this is a little awkward because of the extra protective case - you can use the stylus and onscreen keyboard to acquire data.
For Motion Amplification® - You can detach the tablet and use the Motion Amplification® software. Here again, use the stylus and onscreen keyboard as necessary.
Microsoft Surface Book 2 Update (released about Nov 2017)
The stylus is no longer standard with the Surface Book 2 according to Microsoft.
Check things in this order:
In order to save and replay Raw Video files from another location, all of the original files must be transferred and stored in the same location. There will be a file folder and individual file which both have the same name. The individual file will end in ".RDI" and is recognized by the Motion Amplification® software as a known file type. Clicking it will launch the Motion Amplification® software and load the video.
To extract files from a Compressed (Zipped) Folder follow these steps:
Please see the attached video for a demonstration of the extraction process.
The Gain slider adjusts the sensitivity of the camera’s sensor. Use it sparingly. By increasing the gain, you will brighten your image, but you will introduce more noise and decrease the quality of the measurement. Sometimes this is necessary when the image is too dark. This value is scaled from 0 to 30.0. Always set the Brightness slider first, then add the least gain necessary. You may also want to add supplemental lighting to reduce the need for excess gain. There are three ways to move the slider:
In the attached video the three adjustment methods are displayed. You can also see the effect that moving the slider has on the image.
Version 2.5 UPDATE
The Gain slider plays an important part in Shaft Inspection recordings. Here, you want to set the Gain slider as HIGH as possible and the Brightness slider as LOW as possible. This allows for the shortest exposure time and clearest picture of a rotating shaft.
Behavior in Version 2.3 and earlier:
Lighting is the biggest challenge when recording inside. Because indoor lighting is typically powered by Alternating Current (AC) the fluctuations in light intensity can be seen when using Motion Amplification®. One of the symptoms is found in the article: My recording flashes bright and dim during analysis when I move the Motion Amplification® slider. The Iris M™ System contains helpful tools to automate selecting compatible recording rates. Using the selections from the "Acquisition Mode," "Lighting," "Framerate (fps)" and "Fmax (Hz)" boxes under the "Camera Properties" section of the RDI Technologies™ Acquisition software will configure your recording for compatible frame rates giving you the best quality videos at all Motion Amplification® settings.
Be aware, we have even seen flash rates at frequencies "around" line frequency. So, your filters may have to be adjusted slightly to eliminate the actual frequency.
See the attached videos for locating and using these controls.
During installation, the software contacts the RDI Technologies™ server and validates that installation on that computer.
This is true for both the Acquisition System and the Analysis Only installation on a second computer.
This behavior has changed several times since it was first introduced. In some cases, the original behavior was retained, in some cases, it has been improved and updated. Please see the instructions below for the specific versions.
Appearance and behavior in Version 2.0
In Version 2.0, the ROI icon will appear as shown above. To add multiple ROI's in your video you have to left-click, hold and drag the first box. It will be RED in color. To draw the second box, you had to press the Control [CTRL] key then left-click, hold and drag additional boxes. New boxes will be BLUE, GREEN, ORANGE, YELLOW, PINK, then RED with this sequence repeating. Between each ROI, you have to wait for the measurement calculations to complete before starting to position the next ROI.
Appearance and behavior in Version 2.1
In Version 2.1, the ROI Icons were changed to those shown above. In this version, a "Persist" mode was added.
When the Motion Amplification® software is set to "Standard Mode", your icon will look like this: . In this mode, you add multiple ROIs by following the same procedure as described above for Version 2.0.
When you click on the down arrow between the two icons, your icon will change to this: . To draw ROIs in this mode, you only need to left-click, hold and d
rag with your mouse. Every time you release, an ROI will appear. When you click another location, you will begin drawing a new ROI. Between each ROI, you have to wait for the measurement calculations to complete before starting to position the next ROI.
To switch between the two, simply click on the arrow to the right of the ROI icon, . Choose the mode you would like to activate and click on the name to close the menu:
Appearance and behavior in Version 2.2
In Version 2.2, Standard Mode was changed to "Independent Mode" as shown above. The behavior is still as described in Version 2.0 above, only the name was changed. "Persist Mode" behaves as described in the Version 2.1 section above.
Appearance and behavior in Version 2.3 and Version 2.4
In Version 2.3, the ROI Icon has returned to the original design. However, the behavior is as described under "Persist Mode" in Version 2.1 above. Simply left-click, hold and drag to add ROIs to the video. You can still hold the CTRL, left-click and hold to draw multiple ROIs as well.
You can now click the "Cancel" button as the first measurements are calculated. Early measurements will be suspended until all of the ROIs are placed. Allow the measurements to calculate after placing your LAST ROI and all previously placed ROIs will have their measurements calculated at once saving you time.
For example, if you want to place four ROIs in your video, you can left-click, hold and drag to place the first ROI. As the measurement dialog appears, click "Cancel" and place the second and third ROIs in this same manner. When you place the fourth ROI, allow the measurements to calculate and all four will be presented when done.
Appearance and behavior in Version 2.5
In Version 2.5, the order of the two ROI icons is reversed. Delete is on the left and the Type of ROI selection is on the right. In this mode, you place ROIs by left-clicking, hold and drag in the area where you want to ROI. You can place multiple ROIs by continuing this process everywhere you want an ROI. You can suspend the measurement calculations and complete them with the last ROI placed.
In this version, you have two new ROI types, the “Horizontal Shaft” and the “Vertical Shaft” measurement tools. As the icons indicate, you will be able to measure shaft movement on a shaft which is recorded horizontally using the Horizontal Shaft tool. Shafts recorded in a vertical orientation are measured using the Vertical Shaft tool.
Appearance and behavior in Version 3.0
The ROI Icons appearance is unchanged in Version 3.0, but there is a new “Transient” ROI tool.
This type of ROI will track translational movement and show you the path of such motion.
PURPLE was introduced as a 7th color in the sequence in this version. Now the color cycle, RED, BLUE, GREEN, ORANGE, YELLOW, PINK, PURPLE, RED, will repeat.
The only way to raise the frequency resolution is to increase the time of the recording. Frequency resolution can be expressed as 1/t where t = recording time. For example, a recording time of 1 second will allow you to resolve to 1Hz, at 10 seconds you can resolve to 0.1 Hz, at 20 seconds you can resolve to 0.05 Hz.
In order to increase Fmax, you must 'crop" the collected image. The best way is to decrease the vertical resolution (Height) of the image which allows you to increase the acquisition rate. Decreasing the Width of the recording will also allow you to increase Fmax, but at a slower rate.
See the video below for exactly how to do this and just what it means.
Processor: i7 is recommended, the newer generation of i7 processors is desirable and these are usually labeled 6th or 7th generation
Memory: 16GB of RAM is highly recommended
Hard Drive: SSD is not required, but will improve performance for stabilization, filtering, etc. If you do get a rotating HDD, suggest 7200 RPM.
OS: Win 10 Pro is the version of Windows we have tested and support
In general, you should select the distance and lens combination that allows you to fill the full frame with the entire asset, including the base. It may also be beneficial to include some background objects such as piping or structures. Specifically, it will depend on several things:
Below are examples using five different focal length lenses on the same camera all positioned 5.5 feet (1.7 m) from the object. As you can see, each lens halves the field of view or doubles the zoom.
