Trackit 2D | ||||||||||||||||
| Trackit performs object tracking at 50 frames per second. The obtained data is processed instantly and is on-line available to the user. The orientation of the long body axis of the tracked animal is also measured on-line. Trackit is a data acquistion system that integrates a pan-tilt video camera, a personal computer with a video digitizing board and with special-purpose software. The aim of the system is to follow the object with a close-up zoom, thereby keeping it near the centre of the image. The movements of the camera and details of the grabbed images allow the subsequent calculation of the animals trajectory. | |||||||||||||||||

The concept of 'Trackit': A pan-tilt video camera (VC) obtains close-up images of the flying insect.

| In many experiments it would be desired to be able to vary the stimulus conditions as a function of the animal's behaviour. We provide a flexible and powerful solution to this problem: Positional data is read out in real-time, which can processed in a specific device or on a different computer (platform independently). In this way the stimulus conditions can be controlled and altered during the process of the trial. Trackit 3D Commander is successfully used in a project in which a parasitoid nocturnal fly is tracked in 3-dimensional space (Dr. D. Robert, P. Müller, Bioacoustics Lab, University of Zürich; correspondence to: piemue@zool.unizh.ch). The graph below shows the 3-dimensional trajectory of the fly. The 3D position data is read out to a second computer on line, as the fly approaches an emitting loud-speaker. A second computer reads in the the positional data and is used to trigger a sensory stimulus when the fly is within a certain region, as for instance the shaded region shown in the graph. |
