电视跟踪箱跟踪性能检测仪设计

最小跟踪目标对比度、最小跟踪目标尺寸、最大跟踪目标速度、跟踪精度、目标捕获概率和目标捕获时间等六个指标是衡量电视跟踪箱跟踪性能的重要指标。本文介绍了电视跟踪箱跟踪性能检测仪设计方案、工作原理和组成,包括针对电视跟踪箱的性能检测设计的、基于PC总线的模拟目标产生卡,该卡可以利用软件编程产生目标大小、对比度、运动轨迹、速度和方向等参数都可以精确调整的运动或静止模拟目标。该检测仪已应用于多种电视跟踪箱的性能测试和评价中,与传统的室内标志法相比,具有可编程性好、精度高、通用性强和运动状态可控性好等特点。

A Design of the Test System for TV Tracking Box

These indexes of the least tracking contrast, least tracking target, most tracking velocity, tracking error , target acquisition time and target acquisition probability are important parameters for estimating the quality of the TV tracking box . In this paper, we introduced designing theory and constitute of the test system for TV tracking box including the simulate target producing board. The board can create a moving target that can be changed in size, contrast, movement, speed and direction. The test system has been used in testing many TV tracking boxes, comparing with the way of sign in room, it has excellence in the aspect of programming , precision , currency and movement state.
