Compactly designed camera calibration device for distortion correction that does not require relay lenses.
GEOCAL is a device for camera calibration to correct distortion aberration, using collimated laser light combined with a diffractive optical element (DOE). It can correct distortion aberration in cameras that need to detect moving objects, such as those used in vehicles and security. 【Main Features】 ■ Regular grid generation using infinite distant light ■ Camera position does not require parallel movement (to a certain extent) ■ Easy management of camera rotation angles ■ No relay lens required ■ Very compact design ■ Calibration of wide-field cameras ■ Alignment and adjustment of stereo cameras <Importance of Geometric Calibration> Geometric calibration is essential for camera systems that need to detect moving objects, such as ADAS and security camera systems. Geometrically calibrated cameras can perform more accurate distance measurements, object detection, high-level distortion correction, and positioning adjustments for stereo cameras.

basic information
GEOCAL is available in three versions: the standard model, GEOCAL XL, and GEOCAL IR. 【GEOCAL XL】 GEOCAL XL is ideal for geometric calibration of cameras with large front lenses or when a significant distance between the camera and GEOCAL is required (for example, calibration through a windshield). 【GEOCAL IR】 GEOCAL IR is a version compatible with the near-infrared (NIR) range, which extends the wavelength range of the laser diode to 935 nm for calibration using NIR lighting. ＜GEOCAL Analysis Software＞ GEOCAL comes with standalone software that features a GUI interface for analyzing test results. If you wish to integrate these results into custom software, an API (sold separately) is also available.
