چکیده
Abstract A novel concept of camera modelling for underwater 3D measurements based on stereo utilisation is introduced. The geometrical description the ray course subject to refraction in cameras presented under assumption conditions, which are typically satisfied or can be achieved approximately. Possibilities simplification shown, allow an approximation by classical pinhole modelling. It shown how expected measurement errors estimated, as well its influence result. Final processing data according requirements regarding accuracy performed using several kinds refinement. For example, calibration parameters refined, systematic decreased subsequent compensation suitable error correction functions. Experimental simulations and real obtained two different scanners discussed. If inverse image magnification larger than about one hundred, remaining caused effects usually neglected model used camera-based systems.

Modelling Scattering Distortion in 3d Range Camera
A time-of-flight camera suffers from significant range distortion due to the scattering artefact caused by secondary reflections occurring between the lens and the image plane. The reflected beam from the foreground objects undergoes multiple reflections within the camera device thereby introducing parasitic signals that bias the late-arrival, backscattered signals from the background targets. ...
متن کاملCalibration Techniques for Accurate Measurements by Underwater Camera Systems
Calibration of a camera system is essential to ensure that image measurements result in accurate estimates of locations and dimensions within the object space. In the underwater environment, the calibration must implicitly or explicitly model and compensate for the refractive effects of waterproof housings and the water medium. This paper reviews the different approaches to the calibration of u...
متن کاملCompressive Underwater Video Camera
A tertiary goal, which we plan to explore in depth in future research, is the integration of image compression with automated target recognition (ATR). Two cases are of interest to this study. First, we have shown that one can achieve increased processing efficiency by applying specially configured ATR operations to compressed imagery [Sch97c,d]. Second, we have developed techniques for prefilt...
متن کاملMapping 3D Underwater Environments with Smoothed Submaps
This paper presents a technique for improved mapping of complex underwater environments. Autonomous underwater vehicles (AUVs) are becoming valuable tools for inspection of underwater infrastructure, and can create 3D maps of their environment using high-frequency profiling sonar. However, the quality of these maps is limited by the drift in the vehicle’s navigation system. We have developed a ...
متن کاملMultibeam 3D Underwater SLAM with Probabilistic Registration
This paper describes a pose-based underwater 3D Simultaneous Localization and Mapping (SLAM) using a multibeam echosounder to produce high consistency underwater maps. The proposed algorithm compounds swath profiles of the seafloor with dead reckoning localization to build surface patches (i.e., point clouds). An Iterative Closest Point (ICP) with a probabilistic implementation is then used to ...
