Flock of Birds
应用范围：头部跟踪、手部跟踪、交互式虚拟设计与数据分析、飞行仿真、模拟驾驶、实时三维可视化、遥感、航测、器械跟踪、生物力学研究、三维图形操控
|
Flock of Birds is a 6 degree of freedom (6DOF) tracker used for tracking 1-4 sensors simultaneously.
Each Flock receiver makes up to 144 position and orientation measurements per second. Track the motion of just your head or all the key joints of your body without degradation in update rate or an increase in lag. Whichever way you turn, every motion is captured.
You need not worry about losing data due to blocking problems. The Flock's pulsed DC magnetic fields permeate all non-metallic objects. Even in the presence of metallic structures, the Flock makes its measurements with only a fraction of the distortion errors experienced by AC electromagnetic tracking devices. That's why the Flock is used in harsh environments - ranging from tank and flight simulator to gait labs and movie sound stages.
For sit-down applications in medicine, virtual reality, and simulation, use the economical standard range transmitter to track motions over a four-foot radius. For animation, biomechanics, and walk-around applications, move up to the extended range transmitter (ERT). It increases range to a 10-foot radius and is the choice of animators worldwide for proven long-range performance. Linked together, dual ERTs provide enough coverage to fill a large room.
The Flock employs a separate microprocessor for each of its sensors and a Fast Bird Bus (FBB) to minimize communication time. The result is fast delivery of sensed motions with low levels of lag no matter how many points are being tracked. You never suffer from reduced measurement rates when adding additional sensors.
Flock trackers work with all major computer platforms. Powerful software interfaces are readily available for simulation, virtual reality, biomechanics and medical applications.
The Flock is available in many flexible configurations. Long-range coverage is easily added by 'clicking in' the Extended Range Transmitter (ERT). For quick and easy interface, simply plug in the RS-232 cable to your host computer.

|
Full functionality of the Flock with miniature sensors, as small as 5 mm wide, especially useful for medical imaging. Sensors are small enough to be inserted in endoscopes or attached to probes, trocars, biopsy needles, diagnostic devices, and other instruments for instantaneous localization of their position and orientation.
Model 800 - 8mm sensors. Available with both serial and ISA - bus interfaces. The ISA card version now simultaneously tracks two sensors per card.Model 500 - 5mm sensors. Beta units available Q1, 2001, with a serial interface to your host computer. Designed especially for use with endoscopes and laproscopes. Now available for beta testing.
Real-Time Orientation Tracking 3D-BIRD provides instant orientation tracking for real-time viewing of 3D graphical images and scenes. It is ideally suited for head-tracking applications in which one needs to look around virtual environments and simulated worlds.Magnetic tracking with miniaturized sensors miniBIRD measures the real-time position and orientation (six degrees of freedom) of one or miniaturized sensors. It lets you accurately track the spatial location of probes, instruments, and other devices. With dimensions of just 18mm x 8mm x 8mm for the Model 800 and just 10mm x 5mm x 5mm for the Model 500, each sensor is small enough for both external and internal use.DC magnetic fields overcome blocking and distortion DC magnetic fields avoid blocking problems and yield reduced distortion from nearby conductive metals. Signals pass through the human body without attenuation. Mini sensors may be inserted into a body cavity to accurately record instantaneous position and orientation. Accuracy is unaffected by mounting mini sensors on ultrasound scanheads or non-magnetic stainless-steel
instruments.
Clinical applications miniBIRD collects the spatial data necessary for accurate 3D reconstruction of ultrasound images of the heart, blood vessels, stomach, and other organs. In conjunction with ultrasound devices, it offers non-invasive, radiation-free imaging. In one major new application, its sensors continuously monitor the descent of the fetal head during human labor to optimize outcome while minimizing C-sections. Dual mini sensors are used for differential readings of anatomical structures and for tracking multiple instruments. These approaches provide accurate volume measurements and precise navigation inside the body. For example, miniBIRD ensures that biopsy needles reach their target by correlating needle orientation with ultrasound imagery.

The digital detectors embedded in the frame provide full coverage of performers while minimizing blocked markers. The Instant Marker Recognition instantly reacquires blocked markers for clean data. This means less post processing and a efficient motion capture pipeline.
Benefits
◇544 digital detectors give unprecedented coverage of performer with far fewer occlusions than passive optical systems.
◇42 embedded LEDs give high accuracy of 3 mm and wide angle field of view of each marker producing unprecedented coverage and highest quality data.
◇Real-time engine allows director to direct characters rather than actors. Actors get real-time feedback of performance, and are able to modify behavior to suit the character. Instant Marker Recognition Technology produces virtually no occlusions, and therefore less data gaps.
◇Solid state electronics mean less time and cost associated with maintaining, calibrating, and operating the system.
◇Prop tracking eases post production pipeline by tracking props in original mocap take. ◇Solid cubic frame for easy set up and start up. No continuing calibration, no moving parts and no maintenance.
Applications
3D Character animation for TV, Movies & Games Live Performance Animation Sports & Biomedical Analysis Human Performance Assessment Rehabilitative Assessment/Feedback Active Infrared Optical Tracking - How does it work?ReActor 2 captures the real-time motions of an un tethered performer - free to move in a capture area bordered by 12 modular bars that snap together in minutes. Embedded in the bars are IR detectors and electronics for automatic marker recognition, and data transfer to the ReActor PC.
The performer wears an ergonomically-designed, lightweight motion suit fitted with robust, slim-line active IR markers. These are connected to a belt pack by thin, flexible cables. The belt pack communicates with the ReActor 2 PC via a wireless radio link. Its dual battery packs fit snugly on the waist belt. These batteries power the suit and can be detached for recharge/replacement in seconds.
The ReActor 2 PC performs data processing and outputs time-stamped records to a host computer for instant display of animated motions. Motion files can be transmitted across a network or the Internet for remote visualization, editing, or further processing. Motion files compress to just 100 kilobytes/minute of data to facilitate handling and transmission.
ReActor 2 can be used in natural light and requires no calibration. Since a significant amount of signal processing is already carried out by electronics in the bars and PC, ReActor 2's data is extremely clean. Little or no post processing is required. Occlusion is also handled intelligently thereby minimizing marker dropout.
