Getting started with Basler pylon5 C-API and Embarcadero Delphi 10.1 Berlin

This project provides sample code to demonstrate how to use the pylon5 C-API in Embarcadero Delphi 10.1 Berlin in combination with Basler USB3 Vision and GigE Vision cameras.


This guide assumes that:

  1. you're using Windows 7 OS (or newer)
  2. you're using Basler's pylon Camera Software Suite for Windows v5.0.5 or newer. You can download the latest pylon version from here.
  3. you're using a Basler USB 3 Vision or a GigE Vision camera


Supported functionalities

  1. device enumeration
  2. simple access to camera prameters e.g. width, height etc.
  3. buffer management
  4. single image grabbing
  5. image display in the RAD Studio

The manually created type library file doesn’t currently contain all pylon functions and variable types, but it can be extended by users upon their needs.

PS: do not forget this is a sample private project without any warranty and further support.
