Laser Stripe Profiler Calibration Using Nonlinear Models
The calibration of a laser stripe profiler consisting of a laser stripe projector, camera, and linear motion table is considered. A nonlinear system model is used which accommodates radial distortion in the camera lens. The way in which stripe data is extracted from the camera images leads to a natural formulation of the calibration problem as a nonlinear least squares problem. This can then be...

متن کاملLaser-Video Scanner Calibration without the use of a frame store
Abstract We present a new calibration method for a structured light surface scanner. The new method uses a model-based calibration, accounting for laser stripe and translation stage alignment and the internal and external camera parameters. The inclusion of non-linear radial distortion in the camera model gives an improvement in the calibration accuracy over a linear model. The method has been ...
متن کاملThe DLR Multisensory Hand-Guided Device
This paper presents the DLR Laser Stripe Profiler as a component of the DLR multisensory Hand-Guided Device for 3D modeling. After modeling the reconstruction process, we propose a novel method for laser plane self-calibration based on the assessment of the deformations the miscalibration leads to. In addition, the requirement for absence of optical filtering implies the development of a robust...
