Characterising a High-Speed 3D Surface Scanner for Bat Behaviour Study
نویسنده
چکیده
There has been an increasing interest in studying animal behaviours [1]. In the EU funded project “ChiRoPing: Developing Versatile and Robust perception using Sonar Systems that Integrate Active Sensing, Morphology and Behaviour” [2], the interest is placed on Chiroptera (bats) as bats are the nature’s expert in active sonar sensing [3]. Study of bats’ behaviour is not only of biological interest in the project but also helpful in engineering an active sonar sensing system similar to what bats possess.

Relationships between Hitting Technique and Ball Carry Distance in Cricket
The aim of this study was to identify the technique parameters characterising batsmen who generate large carry distances, ball launch speeds, and bat speeds during a range hitting task in cricket. Kinematic data were collected for 20 batsmen, and a series of ball launch, impact, and technique parameters were calculated for each trial. A regression analysis found impact location relative to the ...
متن کاملApplication of a High-speed Stereovision Sensor to 3D Shape Acquisition of Flying Bats
3D shape acquisition of fast-moving objects is an emerging area with many potential applications. This paper presents a novel application of 3D acquisition for studying the dynamic external morphology of live bats in flight. The 3D acquisition technique is based on binocular stereovision. Two high-speed (500 fps) calibrated machine vision cameras are employed to capture intensity images from th...
متن کاملOnline 3D Acquisition and Model Integration
This paper presents a system which yields complete 3D models in a fast and inexpensive way. The major building blocks are a high-speed structured light range scanner and a registration module. The former generates ’raw’ range data whereas the latter performs a fast registration (ICP) and renders the partially integrated model as a preview of the final result. As the scanner uses only a single i...
متن کاملThe Computation of 3d Pattern Matching as a Tool for Conceptual Freeform Shape Design
Freeform feature fitting is a technique underlying different applications, including reverse engineering, object recognition and conceptual shape design. The latter application poses specific requirements to the fitting technique with regard to speed, robustness and interactivity. On the other hand, the spatial accuracy and the density of the input data can be permitted to be relatively low. We...
متن کاملDetailed image-based 3D geometric reconstruction of heritage objects
The attention in digital documentation and preservation of heritages is always increasing and fast but reliable, low cost, portable and practical solutions are more and more of great interest for archaeologists, restorators and the all heritage community. The goal of this work is to present the developed multi-photo image-based techniques able capture the fine 3D geometric details of such objec...
