How many points are in each point cloud?¶
The image size is 1920 x 1200 for Zivid One+ and 1944 x 1200 for Zivid Two. In both cases about 2.3 MegaPixel, which is the number of cloud points.
How much does the Zivid camera weigh?¶
Zivid One+ weight: 2 kg
Zivid Two weight: 0.945 kg
How much bandwidth does the camera occupy?¶
The bandwidth of Zivid One cameras at max is 2.9 Gbps.
The bandwidth of Zivid Two camera at max is 10 Gbps.
What kind of calibration is performed by Zivid?¶
Zivid cameras come precalibrated from the factory and are ready to use. Our floating calibration takes temperature and iris (aperture) into account. The point cloud provided by the camera is calibrated, which means that X, Y and Z are correct according to real scenery. There is a pixel to pixel correspondence for the X, Y and Z matrices and the color image.
Zivid also offers Infield Correction tool designed to verify and correct for the dimension trueness of Zivid cameras in the field.
Hand-eye calibration is used to calibrate the camera to a robot. It refers to finding the transformation between the coordinate systems. Zivid has an official tool for helping customers with the Hand-Eye Calibration calibration.
In what format can files be saved?¶
The point cloud files can be saved as
*.zdf, which is the format that Zivid Studio and Zivid Cloud viewer use based on netCDF. You can also export the file as a PLY file (*.ply as ordered or unordered) / ASCII points file (*xyz) / Point cloud data file (*.pcd)
What kind of sensor does Zivid use?¶
Zivid One+: 2.35 MP CMOS sensor.
Zivid Two: 2.86 MP CMOS sensor.
What kind of USB cable may I use for Zivid One+ cameras?¶
Zivid One+ cameras come with 5 m copper USB 3.0 cables. Zivid also provides USB 3.0 cables in 10 m and 25 m options. The 10 m and 25 m alternatives are optical extension cables which should be paired with a shorter 0.5 m copper cable.
Long USB copper cables are susceptible to data transfer errors. This is particularly true if the connectors are not tightly connected. For this reason Zivid strongly recommend that the cables are carefully checked before use or if run time errors occurs. It is also strongly recommended to tighten the M2 Jack screws on the camera side when setting up the camera.
For inquiries about obtaining proven to work extender cables contact customersuccess@zivid.com.
What kind of Ethernet cable may I use for my Zivid Two camera?¶
The Zivid Two camera comes with a 5 m CAT6 Ethernet cable. Zivid also provides Ethernet cables in 5 m, 10 m, and 25 m options.
Zivid strongly recommends that the cables are carefully checked before use or if run time errors occur. It is also strongly recommended to tighten the screw on the camera side when setting up the camera.
For inquiries about obtaining proven to work Ethernet cables, PCIe network cards, and network switches contact customersuccess@zivid.com
What depth sensing technology does Zivid use?¶
Zivid uses a technology called “Temporal Structured Light”. This is a technology that integrates a sequence of different spatial encoded patterns. High accuracy depth information is achieved even on structure-less planes.
Can I increase the frame rate while sacrificing on quality and/or resolution?¶
No, this is not possible today. It is something that we intend to make available in the future, but there’s no committed timeline yet.
Is the structured light that Zivid uses in the visual spectrum?¶
Yes, the Zivid camera uses white LED light for vivid colors.
How can I access the log files to forward to Zivid Support?¶
You can find the logs at
%LOCALAPPDATA%\Zivid\API\Logon Windows and$XDG_CACHE_HOME/Zivid/API/Logon Ubuntu.Caution
If
$XDG_CACHE_HOMEis not set use$HOME/.cache.
Is the structured light that Zivid uses harmful to people?¶
Zivid 3D cameras use a white light source, which is tested against IEC 62471 and is classified as Risk Group 2 (see the label at the back of the camera). There is possibly hazardous optical radiation emitted from the camera. Do not stare at operating lamp, it may be harmful to the eyes.
What light class certificate do Zivid 3D cameras have?¶
Zivid 3D cameras use a white light source, which is tested against IEC 62471 and is classified as Risk Group 2 (see the label at the back of the camera).
Will the point cloud data differ when using Zivid Studio and the API?¶
As long as the settings used are the same, there should be no difference between Zivid Studio GUI and the API. If you notice a difference in the data between the tools, ensure that all the settings used are the same. Note that the default settings may differ for Zivid Studio and the API.
What is the expected service life of Zivid camera?¶
Expected service life of the Zivid 3D camera is 50000 hours @ 35˚C. This assumes a typical operating pattern with 500 HDR-captures per hour.
This is not to be mistaken for expected Mean Time To Failure (MTTF/MTBF).
Does Zivid support GenICam?¶
Zivid Software includes a GenICam GenTL producer
Using GenICam with Zivid cameras is tested in following HALCON versions:
19.05 Progress
For other GenICam GenTL consumers, we provide a technical preview. This may allow use of a Zivid camera in other software packages that enable interfacing GenICam GenTL compliant cameras.
What temperatures can I safely run Zivid in?¶
Zivid One+ cameras are designed to work within 10˚C and 40˚C.
Zivid Two cameras are designed to work within 0˚C and 40˚C.
We strongly recommend operating the camera within its specified temperature range.
Caution
Using the camera outside its temperature range can damage the camera and void your warranty. Use the camera out of spec at own risk.
Hint
The point cloud accuracy and stability when using a Zivid 3D camera outside of its temperature specification (e.g. close to 0˚C for Zivid One+ camera) have been improved with SDK 2.4.
How can I process the point cloud data from Zivid?¶
Zivid does not provide point cloud processing software. HALCON, Matrox, and Easy3DObject are examples of paid processing software while OpenCV and Open3D are free alternatives to use depending on the target application.
What material is the Zivid camera casing made of?¶
The Zivid One+ camera has a robust aluminum casing.
The Zivid Two camera is constructed of both aluminum and magnesium parts to create a lightweight and robust casing.
