Calculate 3D Capture Speed

3D acquisition time is the time the camera and scene must remain still, which is also the time it takes for the capture API to return. It depends on:

• Vision engine

• Number of acquisitions

• Exposure time and aperture of each acquisition

• Filters

• Processing power of the connected hardware

Use the calculator below to estimate it for your settings, or see the real benchmarked numbers further down this page. For example, a Zivid 2+ MR130 running the Consumer Goods Fast preset on a high-end PC has a combined 2D and 3D capture time of approximately 150 ms (see Settings Selector based on Capture Speed for more preset benchmarks).

For more information about the point cloud capture process, see Point Cloud Capture Process.

Warning

Be aware that using the Zivid camera at a high duty cycle can trigger thermal throttling to prevent overheating. For more on this topic check out the projector brightness page.

Camera Benchmarks

Below you will find benchmarks of different camera presets with different type of hardware. You can adjust cameras, configuration, and display options to find the data most interesting for you.

Note

Note that settings with the same name may differ across camera models. For more information about recommended hardware please see Recommended Industrial PCs.

You can check your acquisition and total capture time in Zivid Studio and via the SDK.

C++

source

const auto frame = camera.capture2D3D(settings);
const auto frameInfo = frame.info();
std::cout << "Acquisition time:" << std::endl;
std::cout << std::chrono::duration_cast<std::chrono::milliseconds>(
                 frameInfo.metrics().acquisitionTime().value())
                 .count()
          << " ms" << std::endl;
std::cout << "Capture time:" << std::endl;
std::cout
    << std::chrono::duration_cast<std::chrono::milliseconds>(frameInfo.metrics().captureTime().value()).count()
    << " ms" << std::endl;

C#

source

using (var frame = camera.Capture2D3D(settings))
{
    var frameInfo = frame.Info;
    Console.WriteLine("Acquisition time:");
    Console.WriteLine(frameInfo.Metrics.AcquisitionTime.Milliseconds + " ms");
    Console.WriteLine("Capture time:");
    Console.WriteLine(frameInfo.Metrics.CaptureTime.Milliseconds + " ms");

Python

source

frame = camera.capture_2d_3d(settings)
frame_info = frame.info
print("Acquisition time:")
print(f"{frame_info.metrics.acquisition_time.total_seconds() * 1000:.0f} ms")
print("Capture time:")
print(f"{frame_info.metrics.capture_time.total_seconds() * 1000:.0f} ms")

You can also run our C++ sample ZividBenchmark.cpp to benchmark with your hardware.
