AUTOMATIC SCENE CALIBRATION |
摘要 |
Described herein is a method of calibrating a three-dimensional imaging system (300). During calibration, a position (340) and an orientation (330) of the three-dimensional imaging system is determined with respect to a first parameter comprising a real world vertical direction (V w ) and to a second parameter comprising an origin of a three-dimensional scene captured by the imaging system. The first and second parameters are used to derive a calibration matrix (M c2w ) which is used to convert measurements (360) from a virtual coordinate system (M c ) of the three-dimensional imaging system into a real coordinate system (M w ) related to the real world, The calibration matrix (M c2w ) is used to rectify measurements (360) prior to signal processing (380). An inverse calibration matrix (M w2c ) is also determined. Continuous monitoring (370) and adjustment of the setup of the three-dimensional imaging system is carried out and the calibration matrix (M c2w ) and its inverse (M w2c ) are adjusted accordingly. |
