Multimedia-based Camera-Laser Joint Calibration

Line structured light measurement systems are widely used in the 3D model reconstruction in air. When deployed in a multi-media scene, the measurement system will not work effectively due to the failure of general imaging models. To solve these problems, we propose a multi-media-based 3D reconstruction method, in which applying the calibration parameters in the air and considering the refraction of light can improve the accuracy of 3D reconstruction in multimedia without recalibrating sensor parameters. With the help of the system experimental platform, the practicability and accuracy of our proposed method are verified by comparative experiments under common multi-media conditions, respectively.
