1st Vision is pleased to relay that Allied Vision has introduced new Alvium machine vision camera models featuring 4th gen IMX Sony Pregius S global shutter sensors. The sensors feature an improved back side illuminated pixel architecture that can capture light more effectively. This leads to improved quantum efficiency (QE) compared to 2nd and 3rd generation IMX sensors. Because of the decreased pixel size of 2.74µm, higher pixel densities and resolutions for the same optical format are possible.
Allied Vision Alvium
The IMX542 sensor in the 1800 U-1620 models has a 16:9 wide screen format similar to the IMX265 (2nd gen.). It is practically the same size but has almost twice the resolution. So, the FOV is nearly the same but at a much higher resolution. This sensor is especially suited for ITS applications.
The IMX540 sensor in the 1800 C/U-2460 models has an almost square format. Even though it is not much wider than the IMX304 (2nd gen.), it is considerably higher. It is a solid, lower priced alternative to the OnSemi Python 25k sensor, which has a similar resolution and aspect ratio, but is much larger.
The IMX541 sensor in the 1800 U-2040 models has a square format which was only available in the larger IMX367, but is now available as a C-mount camera in a sugar cube housing. This makes it especially suited for microscopy applications.
A summary of the new Alvium USB3 camera is as follows:

Demanding imaging applications require particular combinations of image sensor, lens, and lighting in order to achieve an optimal image. It can be challenging to choose the right components and configure them in a compact space. An attractive solution for many is to use “Imaging Modules” which contain an integrated camera sensor, lens and lighting in an “all in one” housing. A range of imaging modules are available, each configured to optimize component alignment and operations. The end-user may quickly deploy a new system, benefiting from the standardized systems, economies of scale, and expertise of the module builder.

The “Linea Lite” 2k and 4k line scan cameras provide industry-leading performance in a compact package. Built for a wide-range of machine vision applications, the new Linea Lite cameras feature a 45% smaller footprint than the original Linea and are based on a brand new, proprietary CMOS image sensor designed by Teledyne Imaging. This expands on the success of the Linea series of low cost, high value line scan cameras.
Designed to suit many applications, the Linea Lite offers customers a choice between high full well mode or high responsivity mode, via easy to configure gain settings.

The cameras are available in 2k and 4k resolutions, in monochrome and bilinear color. Linea Lite has all the essential line scan features, including multiple regions of interest, programmable coefficient sets, precision time protocol (PTP), and TurboDrive™. With GigE interface and power over Ethernet (PoE), Linea Lite is an excellent fit for applications such as secondary battery inspection, optical sorting, printed materials inspection, packaging inspection, and many more.

2D imaging is long-proven for diverse applications from bar code reading to surface inspection, presence-absence detection, etc. If you can solve your application goal in 2D, congratulations!
But some imaging applications are only well-solved in three dimensions. Examples include robotic pick and place, palletization, drones, security applications, and patient monitoring, to name a few.
For such applications, one must select or construct a system that creates a 3D model of the object(s). Time of Flight (ToF) cameras from Lucid Vision Labs is one way to achieve cost-effective 3D imaging for many situations.
ToF systems have a light source and a sensor.
ToF is not about objects flying around in space! It’s about using the time of flight of light, to ascertain differences in object depth based upon measurable variances from light projected onto an object and the light reflected back to a sensor from that object. With sufficiently precise orientation to object features, a 3D “point cloud” of x,y,z coordinates can be generated, a digital representation of real-world objects. The point cloud is the essential data set enabling automated image processing, decisions, and actions.

Let’s briefly put ToF in context with other 3D imaging approaches:
Passive Stereo: Systems with cameras at a fixed distance apart, can triangulate, by matching features in both images, calculating the disparity from the midpoint. Or a robot-mounted single camera can take multiple images, as long as positional accuracy is sufficient to calibrate effectively.
Occlusion: when part of the object(s) cannot be seen by one of the cameras, features cannot be matched and depth cannot be calculated.
Occlusion occurs when a part of an object cannot be imaged by one of the cameras.
Few/faint features: If an object has few identifiable features, no matching correspondence pairs may be generated, also limiting essential depth calculations.
Structured Light: A clever response to the few/faint features challenge can be to project structured light patterns onto the surface. There are both active stereo systems and calibrated projector systems.
Active stereo systems are like two-camera passive stereo systems, enhanced by the (active) projection of optical patterns, such as laser speckles or grids, onto the otherwise feature-poor surfaces.
Active stereo example using laser speckle pattern to create texture on object.
Calibrated projector systems use a single camera, together with calibrated projection patterns, to triangulate from the vertex at the projector lens. A laser line scanner is an example of such a system.
Besides custom systems, there are also pre-calibrated structured light systems available, which can provide low cost, highly accurate solutions.
Time of Flight (ToF): While structured light can provide surface height resolutions better than 10μm, they are limited to short working distances. ToF can be ideal for or applications such as people monitoring, obstacle avoidance, and materials handling, operating at working distances of 0.5m – 5m and beyond, with depth resolution requirements to 1 – 5mm.
ToF systems measure the time it takes for light emitted from the device to reflect off objects in the scene and return to the sensor for each point of the image. Some ToF systems use pulse-modulation (Direct ToF). Others use continuous wave (CW) modulation, exploiting phase shift between emitted and reflected light waves to calculate distance.
