Run Sample

Introduction​

This document demonstrates how to use the CSVizionSDK C# SDK with practical examples. You can download the complete sample code from the official repository.

Running the Sample Project​

Before building the sample, open the project's .csproj file and make sure it includes the correct references and configurations.

Verify .csproj Settings​

Open the .csproj file in your sample project and confirm it has the proper setup. Here’s an example configuration:

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
    <!-- Target framework version -->
    <TargetFramework>net8.0</TargetFramework>
</PropertyGroup>

<ItemGroup>
    <!-- Reference the CSVizionSDK NuGet package -->
    <PackageReference Include="CSVizionSDK" Version="VERSION" />
</ItemGroup>
</Project>

Replace VERSION with the correct version of the CSVizionSDK package.

Ensure that the target framework matches the one supported by the package, such as:

  • net8.0 (recommended)
  • net6.0
  • or netstandard2.0 for library projects.

Build and Run the Sample​

Follow the steps below to build and run the sample:

  1. Open a terminal (Command Prompt or PowerShell).

  2. Navigate to the sample project directory:

    cd vizionsdk-csharp/samples

  3. Build the project:

    dotnet build

  4. Run the sample:

    dotnet run

Once executed, the sample application will run using the CSVizionSDK library.

Example Usage​

Below are some example usages of the CSVizionSDK functions as demonstrated in the sample project.

1. Start the Device​

Using StringVector to store the availabled camera devices and start the device at index 0:

StringVector devList = new StringVector();
int cam_num = CSVizionSDK.VxDiscoverCameraDevices(devList);
Console.WriteLine($"Devices: {cam_num}");

for (int i = 0; i < devList.Count; i++)
{
    Console.WriteLine($"[{i}] {devList[i]}");
}

VxCamera cam = CSVizionSDK.VxInitialCameraDevice(0);
int ret = CSVizionSDK.VxOpen(cam);
Console.WriteLine($"Open camera: {ret}");

2. Retrieve Device Information​

Get the device name and interface type:

// Get the camera device name
string devName = "";
int ret = CSVizionSDK.VxGetDeviceName(cam, ref devName);
Console.WriteLine($"GetDeviceName: {ret} / {devName}");

// Get the interface type name
VX_CAMERA_INTERFACE_TYPE type;
ret = CSVizionSDK.VxGetDeviceInterfaceType(cam, out type);
Console.WriteLine($"Get interface type: {ret} / {type}");

3. Adjust Device Brightness​

Retrieve and set the brightness of the device:

// Get UVC image processing brightness
long min, max, step, def;
int ret = CSVizionSDK.VxGetUVCImageProcessingRange(cam, VX_UVC_IMAGE_PROPERTIES.UVC_IMAGE_BRIGHTNESS, out min, out max, out step, out def);
Console.WriteLine($"GetUVCImageProcessingRange: {ret}/{min}/{max}/{step}/{def}");

// Set the brightness to 12
ret = CSVizionSDK.VxSetUVCImageProcessing(cam, VX_UVC_IMAGE_PROPERTIES.UVC_IMAGE_BRIGHTNESS, 12, 0);
Console.WriteLine($"SetUVCImageProcessing: {ret}");
