Teledyne Dalsa TurboDrive 2.0 breaks past GigE limits now with 6 levels of compression

Teledyne Dalsa introduces TurboDrive 2.0 for their Genie Nanos

With the introduction of the Genie Nano came Turbodrive which allowed ‘faster GigE than GigE’ speeds. Turbodrive is a lossless hardware encoding scheme that potentially reduces the amount of data to be transmitted from the camera to the computer. Dalsa’s Nanos, which are priced identical to the competition, offers the users the ability to go faster at no extra cost. Note that the user can turn on or off the encoding.

However, the encoding scheme is data content dependent, and therefore if your data varies a lot within an image the compression is minimal. If your data varies a lot from image to image, then using the encoding means that only certain frames will get a speedup resulting in an inconsistent data transfer rate.

Teledyne Dalsa has just recently introduced TurboDrive 2.0, a firmware upgrade for all Nanos. The major enhancement is that now TurboDrive offers multiple levels of encoding. Level 0 is lossless, and each successive level has some potential lossy amount.

The table below indicates quality level, image compression ratio (absolute worst case scenario) and effective bandwidth gain

As you can see, at level 6, you have a worst case compression of 0.33, yet a speed up of 3. Note, this is a worst case situation so you might get a speed up of 3x, yet be at 0.8. The algorithm is data dependent! (more about this in the tech primer)

Depending on the application, various compression levels provide minimal degradation. The following images are shown for comparisons using the varying quality levels.

As you can see, even at level 4, there is very little degradation in the image. It is easy to imagine that with this image, you can still do your image processing yet get a speed up of 68%!

Level 0 “Lossless” to Level 6 indicate the quality level in the images.

Allied Vision’s high-resolution Prosilica GT now with 12, 16 and 25MP ON Semi PYTHON sensors

Allied Vision extends its Prosilica GT Large Format camera platform with three high-resolution ON Semi PYTHON image sensors (Python 12K, Python 16K & Python 25K)

Combined with robust thermal housing designed to operate in extended temperature ranges and fluctuating lighting conditions, the new Prosilica GT Large Format cameras are ideal for high-definition imaging applications with demanding requirements of robustness and design-in flexibility. They provide a great option for high-quality imaging for anyone looking to switch over from existing CCD cameras to CMOS cameras with similar resolutions and optical formats.

Features include:

Extended temperature range (-20 deg. C to + 50 deg. C)
NIR sensitivity up to 1100nm
Modular concept providing various lens mounts (M58, M42, and EF-mount)
Fixed Pattern noise correction, Defect Pixel Correction, and Trigger over Ethernet.

Prosilica GT5120, Prosilica GT4096, and Prosilica GT4090 at a glance

See full specification for the series below:

Prosilica GT5120, 5120 x 5120, 25MP

Prosilica GT4096, 4096 x 4096, 16MP
This is a great replacement for the KAI-16000 CCD sensors!

Prosilica GT4090, 4096 x 3092, 12MP

Now that you have a great high resolution camera, what lens works best?

High resolution cameras with the ON Semi Python sensors are great, but only as good as the lenses you use! It is imperative to have the sensor sizes matched with the lens formats. Additionally, we need to make sure the lens resolution is adequate for the image sensor pixel size.

To aid in the lens selection, we have the following recommendation on lens series. Recommendations as follows

Prosilica GT5120, 5120 x 5120, 25MP: This camera has a 32.58mm diagonal image sensor, so a F-mount lens is required. Two options are Kowa and Schneider
KOWA – F mount series
Schneider – F mount series

Prosilica GT4096, 4096 x 4096, 16MP: This camera has a 26.06mm diagonal image sensor, also requiring a F-mount lens.
KOWA – F mount series
Schneider – F mount series

Prosilica GT4090, 4096 x 3092, 12MP : This camera has a 23.09mm diagonal image sensor which falls into a 4/3″ format.
KOWA 4/3″ lens series

As a note, as the pixel size is 4.5um, this is not as demanding on the lens resolution and will only require 111 line pairs/mm (lp/mm) making these adequate selections.

Learn about 1stVision’s new OEM 1” machine vision lenses which provide excellent price vs performance ratios

For many years 1stVision has offered several lines of OEM machine vision lenses. These lenses are ‘unbranded’ but they are made with the glass of one of the big three Japanese optical manufacturers.

1^st Vision lenses have excellent optical performance for a great price currently offering a product line designed for a 2/3” image formats with 2MP and 3MP resolutions.

Advantages
The OEM machine vision lenses offer some distinct advantages:

They are less expensive than similarly performing ‘branded’ lenses
When designed into instruments for resale, all issues come back to the original manufacturer. The end user cannot bypass the manufacturer, ensuring you, when your users have problems, you know about them!
With a good price point, the 1″ format can be used for all smaller sensor sizes using the “sweet spot” of the lens!

What’s new? OEM 1” Optical format machine vision lens.

Recently, 1stVision have begun offering a new OEM line of 1” format, high performing 2 and 3 MP lenses, which offers all the above advantages, but you can now use it with the new Sony Pregius and On Semi Python sensors that require lens optical formats greater than 2/3” (For example the Sony Pregius 2MP ( IMX 174, IMX249 ), 8.9MP ( IMX267, IMX255 ) and ON-SEMI 5MP Python 5000 sensors ) Search on the image sensors here

Learn how the new IDS Imaging GigE Vision IP65/67 cameras can save you money

IDS Imaging Factory Automation (IP65/67) cameras have been released with key features to help save money on industrial installations.

The new versions are “plug & play” with 3rd party GigE Vision software such as Cognex Vision Pro & National Instruments Vision software.

The IDS Imaging GigE uEye FA (Factory Automation) industrial cameras are specifically designed for harsh environments, providing IP65/67 protection using a GigE interface.

Using a water tight lens barrel and M12 connector eliminates the need for costly IP65/67 enclosures, saving space and additional assembly costs. Attractively priced, the FA cameras are an excellent camera for harsh environments versus standard cameras with enclosures.

Key Features are as follows:

IP65 / IP67 Protection – Eliminates the need for an additional costly enclosure, protecting against dirt, dust and water splashing.
GigE Vision compliant models – “GV” models available for use with GigE Vision compliant 3rd party vision software or use with the robust IDS Imaging Cockpit software and SDK using the “UI” models
Compact size with IP65/67 protection – Measuring 41mm x 52mm x 43mm long, the camera design provides less volume than using additional enclosures with non IP rated cameras
8-Pin IP Rated connectors – Used for GPIO, trigger and flash within harsh environments.
GigE PoE Interface – Using Power over Ethernet (PoE), one cable can be utilized for data and power saving money on installations.
Resolutions from 2.3 to 5MP using the Popular Sony Pregius CMOS image sensors (IMX249, IMX265), IMX264) in Mono and Color models
