|1. (WO2018201677) BUNDLE ADJUSTMENT-BASED CALIBRATION METHOD AND DEVICE FOR TELECENTRIC LENS-CONTAINING THREE-DIMENSIONAL IMAGING SYSTEM|
|Title:||BUNDLE ADJUSTMENT-BASED CALIBRATION METHOD AND DEVICE FOR TELECENTRIC LENS-CONTAINING THREE-DIMENSIONAL IMAGING SYSTEM|
Disclosed in the present invention are a bundle adjustment-based calibration method and device for a telecentric lens-containing three-dimensional imaging system. In the method, a camera apparatus having a telecentric lens and a projector apparatus having a telecentric lens are employed in a three-dimensional imaging system, a bundle adjustment technique is employed to perform non-linear calibration on the camera apparatus and projector apparatus, and calibration parameters of the calibrated camera apparatus and projector apparatus are employed to calibrate the three-dimensional imaging system. By employing the bundle adjustment technique to effectively reduce influences of errors of a target on calibration accuracy of the three-dimensional imaging system, the present invention effectively improves the calibration accuracy, and accordingly enhances precision of the three-dimensional imaging system.
