Revolutionary retro-reflective calibration technology enabling microsecond-precision calibration for event cameras without traditional image limitations
Event cameras (DVS - Dynamic Vision Sensors) represent a paradigm shift in computer vision, capturing changes in pixel intensity rather than absolute brightness. This asynchronous operation enables microsecond temporal resolution and extreme dynamic range, but makes traditional calibration impossible as they don't produce conventional images.
CalibWorks developed a groundbreaking retro-reflective calibration system that solves this fundamental challenge. Our solution uses a specially designed retro-reflective calibration board paired with a high-frequency strobing light source. The retro-reflective material returns light directly to the camera, creating solid pattern visibility in the event stream that mimics traditional calibration images without the size limitations of LED-based approaches.
Patent-pending technology for event camera calibration
Overcoming fundamental event camera limitations
Event cameras only detect changes, making traditional static calibration patterns invisible. Our strobing approach creates continuous events.
Conventional flickering LED boards are limited in size and resolution. Retro-reflective technology removes these constraints entirely.
Our controlled high-frequency illumination overwhelms ambient light changes, ensuring consistent calibration in any environment.
Achieving sub-pixel corner detection in asynchronous event streams through advanced temporal accumulation algorithms.
Synchronized calibration of multiple event cameras using phase-locked strobing patterns for stereo and array configurations.
Joint optimization of intrinsic parameters, lens distortion, and temporal biases specific to event camera sensors.
