New Version utilius® vs

The new version 4.5 of our video analysis system adds to the standard formats DV/AVI and WMV support for the video formats MPEG-2 and H.264/MPEG -4 AVC for the video cut. You can also record with the video format H.264/MPEG -4 AVC and,  if you own an HDV camera,  with the HDV format.
The snapshot layout module in the new version 4.5 enables you to illustrate a motion sequence. You can present a choice of characteristics from motion phases.
Using utilius® vs standard you can replace characteristics from your category system automatically. If, for example, you associate team A with the characteristic ““Defense” to team B. You can export and import graphical category layouts in order to exchange them with other users of utilius vs. In the new version of utilius® vs standard, you can output your analysed scenes to separate video files. This allows for more flexibility in your evaluation.
                                                                                                                                             
The update to version 4.5 is available for a fee. You can easily order it from our sales team. Please write an e-mail to s.scholz@ccc-software.de

The slightly different side of ccc

Since its foundation in 1990 ccc software gmbh has been busy with developing individual software solutions for the industrial sector. We focus on the field of IT solutions for medium-sized producing business predominantly in the metal, glass, and solar trades. ccc distinguishes itself as “tailor-maker” of individual solutions. These optimize the manufacturing management (MES = Manufacturing Execution System) and bridge the informational gap in production between the company level (ERP systems, production planning systems) and the control level (automation/process level). The ccc industry software provides the most important information on the manufactured products and the production processes on a button click, offers the back-tracking of products, makes logistics processes easier, ensures quality requirements, or reduces paper-usage in the manufacture. The ccc solutions are applied in work preparation for detailed planning, in control stations for visualization, and for personal planning. They comprise tools for container optimization, product carrier tracking, tools management, or the Electronical Shift Book.

Coming soon:  the measure module for utilius® fairplay 5

You can measure paths, distances, angles, (angular) velocities, or (angular) accelerations with just a few clicks in your video. The easy-to-use measure module allows you to measure not only frontally. With a suitable calibration you can even measure in a perspective plane (e.g. in an oblique view on a playing field).
Mathematical algorithms support you at your work: values between the measure points are interpolated, i.e. when measuring velocities, for every frame you get a realistic value for position, velocity, and acceleration of an object.

Successful test of a prototype of our new video monitoring system for technique analysis

At the moment we develop a complete solution for high-speed recordings of gymnastics training exercises for the Sports Science Faculty of Leipzig University. Short exercises on the high bar, parallel bars, or on the floor are recorded at 80 frames per second using Basler network cameras. The system consists of 9 cameras, one server, a video projector, and a laptop with touch input.
The test verified the recording from multiple cameras synchronously. This enables the analysis of an exercise from multiple viewing angles. In a final stress test we successfully recorded videos at 80 frames per second from all 9 cameras synchronously.

You ask, we answer: Which video cameras are suitable for use with utilius® fairplay 5?

(Part 1 - Webcams)

We distinguish between 4 types of cameras:

1. Webcams that are integrated in a notebook or connected by USB on the PC.
2. DV  and HDV cameras or HDV converters that are connected by firewire on the PC.
3. Cameras that record to hard disks or storage cards.
4. IP cameras, i.e. cameras that are addressed directly over the network or by WLAN.

Today’s article deals with the webcams nowadays available in high quantity. Beside the cameras integrated in notebooks, webcams for the USB port are available for purchase in the price range of 10 to over 100€. At present very few models support the fast USB 3.0 interface, so notebooks with USB 2.0 interfaces are sufficient for using webcams.

The standard resolution, particularly of integrated webcams, is 640 x 480 (VGA) and, depending on the model, extends to 1920 x 1080 (Full HD, also called 1080p). Videos may generally be recorded with up to 30 frames per second. Some models, like the Logitech HD Pro Webcam C910, can record even up to 60 frames/sec at a resolution of 640 x 480. Those interested in technical details may find on Wikipedia (link to http://en.wikipedia.org/wiki/Display_resolution) a comprehensive description of video resolutions.

The biggest drawback of webcams at present is the fact, that they record video data almost without compression or as an MJPEG stream. This comes with a high data rate that pushes the present techniques at their limits, in particular with the higher resolutions. Thus fewer frames per seconds can be recorded or frames will even be dropped during recording.

A solution may be new types of webcams like the Logitech HD Pro Webcam C920 that transfer the video compressed already in the H.264 format. In August, this camera generation will also be supported by the CodecPack (Link) of utilius fairplay. This reduces the size of the recorded video file approximately by the factor 10.

Another important part in recording from webcams is the installed driver for controlling the camera. No-name webcams or Microsoft products generally use the standard driver from the Microsoft operating system. There are no known issues with recording from webcams with this driver. Camera manufacturers such as Logitech and others bring along their own drivers that usually interpose image optimization processors. This might lead to a higher workload of the system and might increase the number of dropped frames. One solution to this problem is using the standard driver with these camera types as well. You can find a tutorial (Link) in our download section.

In general we recommend higher-quality camera types like Microsoft LifeCam Cinema or LifeCam Studio as these are fitted with a bigger recording chip and high-quality lenses. This achieves a higher image sharpness, higher fidelity, and less noise even at poor light conditions.

The biggest difference between webcams and other camera types is the missing optical zoom. This might result in restricted recording scenarios for the video feedback training. The alternative may be DV and HDV cameras that we will elaborate on in our next article within this series.
