Machine vision: Powerful core technology

Teledyne DALSA camera features

Outstanding features for easy and reliable operation

Teledyne DALSA cameras feature a large number of sensor formats and characteristics. This enables them to cover a vast range of industrial imaging applications.

Besides the sensor functionality, several sophisticated industry grade features have been developed by Teledyne DALSA that are present in many models. Among others, these include trigger-to-image reliability(T2IR) to safeguard the image acquisition process and TurboDrive to extend the bandwidth of GigE Vision, along with a number of image quality enhancement options.

Features that make Teledyne DALSA cameras outstanding

Increased speed with TurboDrive

The proprietary TurboDrive feature utilises lossless data compression and transmission to allow data transfer rates that exceed the standard data throughput of GigE Vision systems (typically 115 MB/s). GigE Vision cameras equipped with TurboDrive will therefore be able to achieve faster frame rates than before. All of the benefits of GigE networks - such as mass market components, generic protocols and Ethernet technology for fast and inexpensive communication for distances of up to 100 m - can still be used. Engineers can therefore build on proven technology. This keeps design and support easy, while opening up a lot of potential to increase the speed of the application.

Multiple areas of interest (AOI)

Many Teledyne DALSA cameras support up to 4 areas of interest within the image. Less image data lowers the bandwidth required, which results in an increased frame rate. As the host software does not need to extract the regions of interest anymore, data processing on the host becomes faster.

Trigger-to-image reliability (T2IR)

With the trigger-to-image reliability (T2IR) framework, the image capture process is controlled and monitored end-to-end from the trigger to the transfer to the host memory. This way, data loss is clearly tracked and the reliability of the overall inspection process is improved.

Multiple regions of interest for flat field correction

Flat field correction (FFC) can be used to correct high intensity variations caused by either illumination or lens properties. Teledyne DALSA devices provide up to 4 regions to be specified for flat field correction. A well calibrated image improves and simplifies image processing. It requires less complex image operations and therefore helps saving development time.

Flexible bandwidth limit with burst mode

With the burst mode, the frame rate is not limited by the GigE Vision bandwidth. By combining the high data acquisition rate in the onboard image buffer and comprehen­sive cycling modes and readout control, applications with fast burst acquisition can be realised. In this mode, images can be acquired at the maximum frame rate of the sensor with the data buffered on the main storage of the camera. The buffered data is only transferred during camera idle times e.g. when a conveyor belt moves forward.

Several camera configurations at once with cycling mode

Cycling mode implements a method to use various different user-controlled configurations. This allows sequences to be set up with different light sources, lighting angles, exposure times, gains etc.. In this way, a single pass with a single camera delivers a high amount of information which is comparable to that of multiple cameras or combinations of camera and frame grabber. With this feature, costly and complex hardware solutions can be avoided, since e.g. multiple illumination variants of the same object increase failure detection and production security. It can also reduce inspection time in cases where various illumination set-ups are mandatory to inspect one object.
