The Basler ace cameras series is one of the most comprehensive lines of compact area scan cameras in the industry. The new Basler ACE 2 Pro cameras leverage a dedicated on-board FPGA to offer unique compression and sensor simulation functions that will let you optimize camera bandwidth and replace discontinued cameras with almost any sensor configuration through a simple interface, all without tapping into host PC resources.
Leveraging the on-board processing, Compression Beyond precisely controls image compression prior to the image output from the camera, reducing bandwidth requirements of the camera’s Gig-E or USB3.0 data stream and increasing camera frame rates by 2X-3X. No additional PC processing resources are required.
Not every application requires the same amount of compression. To provide as much leeway as possible, Basler goes one step further: In order to find the optimal balance between image size and image quality for the application, you can individually adjust the compression factor and also choose an even stronger, but then lossy compression to achieve the best result for your requirements.
Many OEMs and End Users have made significant investments in machine vision and image analysis technology that was originally built around a specific image sensor, with a specific physical size, pixel density, and pixel size. Chances are, that image sensor no longer exists in any of the currently available cameras. Now, the only way to source these older cameras is to take a chance on used cameras bought through online shopping.
Pixel Beyond is a unique Basler function for uncomplicated sensor redesign through individual adjustment of pixel size and sensor characteristics in a simple-to-use interface, with transparent results from the camera. This is useful for replacing a discontinued sensor, as the pixel size and resolution used by the camera can be specified, once a suitable new Basler camera is selected.
How Does Pixel Beyond Do This?
Binning, or grouping of pixels, is often performed to replace a discontinued camera sensor by replicating its pixel array. Conventional binning takes place at the sensor level, allowing integer multiples, such as 2×2 or 3×3, for the binning operation. However, with this limitation, the resolution can only be reduced in big leaps – for example to ¼ or 1/9. The optimal target is often in-between, not possible with integer binning.
Basler’s Pixel Beyond offers a decisive advantage: it leverages the on-board processing unit to use decimal numbers, in addition to integer factors, when specifying the size of the bin. The result is significantly more flexibility!
Thanks to Pixel Beyond, all conceivable resolutions between ¼ and the respective maximum sensor resolution can be specified. Using a powerful FPGA, this pre-processing of the pixels takes place directly on the camera. A novel interpolation method developed by Basler serves as the basis.
Compression Beyond and Pixel Beyond are currently available on Basler ace Pro cameras from 2.3MP to 8.3MP. Additional models will be added to take advantage of the ace Pro features.
Pixel Beyond Permits Binning in Decimal Sizes
Basler’s CoaXPress 2.0 camera, the Boost, is available with high-resolution sensors from Sony and ON Semiconductor, providing images up to 45MP at 15fps.
The Boost series is an excellent choice for applications that require high data rates and resolutions, as well as when the camera’s image data must be transferred over longer distances. These cameras are ideally suited for applications in the semiconductor and solar industry, display inspection, print inspection, food inspection, and medical technology.
Boost global shutter cameras offer very high bandwidth and extended cable lengths to 40m. They are available in monochrome and color.
Adapters for C-, F-, and M42-mount lenses are available.
Basler Boost CoaXPress 2.0 Camera and CXP-12 Interface Card
The Basler CXP-12 CoaXPress 2.0 interface card is tailored to the Boost and is configurable by Pylon through its desktop application or SDK. The Pylon driver is used to configure both the camera and the interface card, minimizing installation effort and ensuring compatibility.
All Basler cameras can use the Pylon Camera Software Suite from Basler.
The pylon Camera Driver for the Robot Operating System (ROS) is an open source project that allows Basler GigE Vision and USB3 Vision cameras to be used more easily in robotics applications.
Basler’s Full Lineup of Machine Vision Cameras
It is challenging to overcome brightness variations across a captured image to extract details from both darker areas and bright, sometimes oversaturated, areas of the image.
Pixelink has directly and transparently addressed this with its on-board HDR Imaging. When the HDR function is enabled, two images, one low-gain and one high-gain, are output to the built-in FPGA to process an HDR image. Using the HDR function cuts the maximum camera frame rate in half. However, the 7.1MP color or monochrome camera is still running at 28fps and the frame rate for the 2.8MP color or monochrome camera is 70fps, even with HDR “on”. This is plenty of camera speed for most applications.
As seen in the example above, the combination of a low gain image (left) used for bright areas of a scene, along with a high gain image (center) used for dark areas of a scene, allows details to be discerned in both the bright and dark areas of the camera’s computed output image (right) using HDR.
The Low Gain and High Gain Images are Created Simultaneously, Processed On-Board the Camera, and the HDR (High Dynamic Range) Image (right) is Output from the Camera.
