Andy Dai developed a HITL Camera Emulator module for the UWARG/common repository, enabling automated integration testing of camera data paths without requiring physical hardware. Using Python, he implemented image processing and virtual camera emulation to stream images directly to a virtual device, supporting image cycling and frame-rate control for realistic test scenarios. The module features robust error handling for both virtual camera initialization and image loading, ensuring stable and reliable test execution. By integrating the emulator into CI workflows, Andy reduced hardware dependencies and provisioning time, improving test coverage and accelerating early defect detection for flight-readiness and continuous integration pipelines.
