The Biomechanics Laboratory makes quantitative information concerning human motion available to clinicians and researchers at the NIH. The BEIP has upgraded Dr. Stanhope's Vicon Motion and Image Analysis System by designing and fabricating six video-camera units, each with a variable-intensity, dual-wavelength infrared strobe. The upgrade solved many of the original Vicon system's problems, but fast motion analysis is still limited by the system's slow frame rate of 25 frames per second. The Biomechanics Laboratory requires a system to take data at 2000 frames per second. To satisfy this requirement, Dr. Stanhope requested that the BEIP develop a three-dimensional motion measurement system, using a concept patented by Dr. Andrew Dainis. The funds for this project are from a CRADA and have been placed with the BEIP. In collaboration with the Biomechanics Laboratory and Dr. Dainis, the BEIP will develop, fabricate, and test the system electronics. Dr. Dainis will develop the optics for the CCD linear arrays and the system software. The idea of Dr. Dainis's patent is that each camera has four linear CCD arrays, with each array having a specially designed lens. The arrays are placed on the face of the camera in a special pattern to translate a light source from a target into its spatial coordinates.

生物力学实验室提供有关 提供给临床医生和研究人员。 的 BEIP升级了斯坦霍普博士的Vicon运动和图像分析 通过设计和制造六个视频摄像机单元，每个单元 一种可变强度双波长红外闪光灯 升级 解决了许多原始Vicon系统的问题，但快速运动 分析仍然受到系统25帧缓慢帧速率的限制 每秒 生物力学实验室需要一个系统， 每秒2000帧的数据。 为了满足这一要求，博士。 斯坦霍普要求BEIP开发三维运动 测量系统，采用安德鲁·戴尼斯博士的专利概念。 该项目的资金来自CRADA，并已与 的BEIP。 在与生物力学实验室和博士合作。 戴尼斯，BEIP将开发，制造和测试系统 electronics. Dainis博士将开发CCD线性光学系统 阵列和系统软件。 戴尼斯博士的专利理念是 每个摄像机具有四个线性CCD阵列，每个阵列具有 特别设计的透镜。 阵列放置在 一个特殊模式的摄像机，用于从目标平移光源 空间坐标。
