摘要：Embodiments of the present invention disclose a parameter calibration method.The method includes: acquiring a calibration template image, where the calibrationtemplate image is obtained by photographing a calibration template; performing corner
detection on the calibration template image to extract image corners; calculating a radialdistortion parameter according to the extracted image corners; performing radialdistortion correction according to the calculated radial distortion parameter, so as toreconstruct a distortion correction image; and according to a perspective projectionrelationship between the calibration template and the reconstructed distortioncorrection image, calculating intrinsic and extrinsic parameters to implement parametercalibration, where the intrinsic and extrinsic parameters include: a matrix of intrinsicparameters, a rotational vector, and a translational vector. The present invention may beapplied to parameter calibration for an imaging apparatus such as a camcorder and acamera in a case of a high distortion.
