I have 2 applications where I need very uniform lighting across a large area (one is 52"x24", the other is 62" x 24", though other designs are possible). There are 2 camera is in the middle of this. I've reached out to several manufacturers/distributors for a light this large and with the specified ~25,000 Lux at .5 meters, but have been unable to get a quote. Does anyone know of a manufacturer who can do this?

Hi, we are working with a sort of complex system with 8 GigE Allied Vision cameras running in 12Bit PixelFormat mode connected to a Switch with a 10Gig uplink to a virtual machine (ESXi) on which our software grabs the images. All Cameras are only used to take single frames, no video. At least 4 cameras are triggered by the same hardware trigger to grab a frame of an object. In the worst case even 8 Cameras may grab at the same time. In the last time we were facing problems with incomplete frames. We only have one try to grab the frame since the object will moving away. We tried with different parameters like PacketSize of 9K and Receive Buffers in the hardware adapters and virtual network adapters but this won't fix the problem for us. The switch itself does not report any errors and the network traffic seems not to be at any limit. It seems like the VM is having some trouble here. Using Wireshark to take a look at incoming GVSP Packets and outgoing GVCP Packets indicates that Packets are missing on the receiving side and requested for retransmission but only up to some limit. We can see that for ~200ms not a single GVSP Packet is received, like a short 'hickup'. What we want is to get this as robust as possible since we have up to 10 seconds before the next object triggers a new grab. So we have plenty of time to wait for the frames if only possible by the SDK. From my understanding several GVSP Parameters exist capable to be tuned that way but these are either not implemented in the SDK or some internal timeouts make it impossible. Has anyone experience with such a system and the GVSP protocol? Sidenote: We have set the camera bandwidths down to 10 Mb/s but this seems not to solve the problem. Looks like the problems lays in triggering multiple cameras at exactly the same time. Best regards

Would appreciate tips and proposals for solving the following application: I would like to build a system that is able to identify random (X, Y) coordinates with an accuracy of ca. 0.5 mm of a small amount (less than 24) of solid pins on a plane. The pins hit the plane randomly and consecutively one by one. They can be a bit tilted, so the position of the pin cannot be determined from the far end, but rather from the point where it is attached to the plane. The pins are made of carbon fibre or aluminum

I am creating a new GigE Vision compliant camera and am defining all of the registers. Registers will be continually defined, added, changed etc. When the register definitions change, I want to be able to auto generate the XML against the genicam schema. Is there a recommended way to do this? MS excel :- / ?? Ideally I'd like to be able to version control this register set wherever or however it is stored.

Hello. I want to implement a camera which supports GigE Vision on a mobile robot. The robot main control is reachable in the company intranet via W-Lan and has an ip-address of the address range 12.12.XXX.XXX. The main control of the robot works as a router and builds an own subnet for the components on the mobile robot. The camera is integrated in this subnet. The subnet uses the address range 192.168.XXX.XXX. Is it possible to reach the camera in the subnet by a workstation in the company intranet? We have already implemented the portforwarding for GigE Vision in the robot control which forwards the request from a workstation in the company intranet to the camera in the robot subnet. But it isn’t possible to find the camera with GigE Vision Tools from the intranet. The main question is: Does GigE Vision support network routing? Thank you for your efforts.

I need info on the CM-030GE. I'm having trouble keeping a connection with the camera. How is it marking traffic as video? Is it using IP-TOS , 802.1p, or DSCP? And what is the exact marking it is using based on the type?

I need an inline vision/scaning/laser or other system to check pin locations/tolerances that are applied by robot in production.

We have a robot placing pins on a flat glass surface. Then the product get autoclaved, then ground and then other attachments are added via urethane glue. We have an issue that we think the robots are not capable, and we want to add a vision/scaning/camera/laser system that will check the 4 pins to the math data to positions and tolerance. If the part is rejected, we need a signal and a robot will pickup the part and set it aside. We have a 2nd area we also want to do a similar check, since the part goes through a heating cycle. We want to make sure that the pin position did not change and are still go to the math. All this must be automated and data for each part must be stored for SPC work. Need help with coming up with a system in line conveyor to improve quality.

Is there a light combination that can take pictures of light brown plastic bottle with water droplets to detect if the cap is on straight or if it is crooked? Cap is just slightly darker than bottle. Water droplets are causing problems. Can a blue light help or an IR backlight?

I am working on outdoor system for detecting fast moving objects. I need an inexpensive solution - 4 cameras shooting @ ~40 fps, 2MP, GIGE, frame level synchronization - in this case minimum 25 ms accuracy (1/40). I need roughly about 100 degrees H viewing angle per camera. The idea is to detect the objects and recreate their positions in X-Y-Z. Does anyone have any idea about the hardware setup? Its really tricky to find the right combination between sensor and optics to achieve the desired FOV at reasonable price (camera + housing + lenses should not be more than 500-600 USD). Another thing is the the synchronization, I want it to be as simple as possible, no additional trigger boxes and cables, so the sync must be done via PTP. The problem is not many cameras support PTP which makes the choice even harder or impossible.

I am an online bookseller and currently we sort about 1 million books a month using a non automatic process with reps. scanning a bar code. We'd like to find a company that can build a sorting system using cameras and high speed conveyors. Do you know of a member(s) that might might be able to help?

I've been working with laser profiling sensors to generate 3D images and inspecting them with vision tools. Usually these devices only give you what is called a height image. Using this image I can measure almost anything I want but I cannot read a 2D code printed on an object or inspect the color/grayscale value of the same object. Is there a device that can deliver both Height Image and "normal image" (similar to one from a camera) or should I just use a profile sensor and camera at the same time?

I currently have an outdoor vision system that detects logs on a stepfeeder. I am using a Cognex insight 7050 with 3.5mm focal length lens to provide me with a FOV of around 3 meters. This works well except I am having problems with sunlight causing glare and shadows that either causes the camera to false detect, or not detect at all. Could anyone recommend lighting/lens/filters that may help?

We are looking for a solution to be able to identify various types of door and windows and measure their height and width, from Architectural floor plans (blueprints). There are no standards how these doors are drawn (no specific model / pattern). These blueprints/ floor plans are only available in somewhat flat PDF’s (no metadata and no vectors). Can anyone give us some suggestions on software we can use?
