Baumer工业相机是一款高性能的工业相机,堡盟工业相机是其一种型号。它们可以通过BGAPISDK来实现JPEG图像压缩功能。下面将介绍如何在C#中使用BGAPISDK来实现JPEG图像压缩功能,并提供部分代码示例和代码注释。
首先,需要在项目中引用BGAPISDK。可以在Baumer官网上下载并安装BGAPISDK,然后在项目中引用相应的DLL文件。
接下来,需要初始化相机并设置JPEG图像压缩参数。以下是一个示例代码:
csharpusing BGAPI2; using System; class Program{ static void Main(string[] args) { System.Console.WriteLine("Initialize the system"); System.Console.WriteLine("______________________ "); // Initialize the system System.Console.WriteLine("Loading the C++ API"); BGAPI2.SystemList systemList = null; try { systemList = BGAPI2.SystemList.Instance; } catch (BGAPI2.Exceptions.ResourceException ex) { System.Console.WriteLine("Loading the C++ API failed: " + ex.Message); return; } // Open the first system try { foreach (BGAPI2.System system in systemList) { system.Open(); System.Console.WriteLine("Open the system: " + system.FileName); break; } } catch (BGAPI2.Exceptions.ResourceException ex) { System.Console.WriteLine("Open the system failed: " + ex.Message); return; } // Open the first camera BGAPI2.InterfaceList interfaceList = null; try { interfaceList = system.GetInterfaces(); interfaceList.Open(); BGAPI2.Interface interfaceObj = interfaceList[0]; interfaceObj.Open(); BGAPI2.DeviceList deviceList = interfaceObj.GetDevices(); deviceList.Open(); BGAPI2.Device device = deviceList[0]; device.Open(); System.Console.WriteLine("Open the camera: " + device.TLType + " " + device.DisplayName); } catch (BGAPI2.Exceptions.ResourceException ex) { System.Console.WriteLine("Open the camera failed: " + ex.Message); return; } // Set JPEG compression parameters try { device.RemoteNodeList["PixelFormat"].Value = "Mono8"; device.RemoteNodeList["JPEGCompressionQuality"].Value =80; device.RemoteNodeList["JPEGCompressionRate"].Value =10; System.Console.WriteLine("Set JPEG compression parameters: " + device.RemoteNodeList["PixelFormat"].Value + " " + device.RemoteNodeList["JPEGCompressionQuality"].Value + " " + device.RemoteNodeList["JPEGCompressionRate"].Value); } catch (BGAPI2.Exceptions.IException ex) { System.Console.WriteLine("Set JPEG compression parameters failed: " + ex.Message); return; } // Close the camera try { device.Close(); System.Console.WriteLine("Close the camera"); } catch (BGAPI2.Exceptions.ResourceException ex) { System.Console.WriteLine("Close the camera failed: " + ex.Message); return; } // Close the system try { system.Close(); System.Console.WriteLine("Close the system"); } catch (BGAPI2.Exceptions.ResourceException ex) { System.Console.WriteLine("Close the system failed: " + ex.Message); return; } } }
在上面的示例代码中,首先初始化了系统,并打开了第一个相机。然后设置了JPEG压缩参数,包括像素格式、压缩质量和压缩比率。最后关闭了相机和系统。
通过以上示例代码,可以看到如何使用BGAPISDK来实现JPEG图像压缩功能。在实际应用中,可以根据具体需求来设置不同的压缩参数,以满足不同的应用场景。
