试飞机载测试系统一体化验证平台的设计与实现

为提高智能车对多车道的实际道路车辆行驶环境的适应性，提出了一种基于三车道模型的车辆检测方法。方法在预处理的基础上利用极角及位置约束的Hough变换得到可能的车道线信息并利用消失点对车道线进行筛选；利用三车道四线模型对车道线进行匹配；对于每条车道，分别利用车辆灰度信息对车道线内车辆进行识别，并利用视频的连贯性对车辆识别结果进行修正并跟踪车辆。该算法通过对车道线的二次筛选，提高了三车道模型的准确率，进一步提高了对于不同车道车辆识别的正确率。实验结果表明，在结构化道路上，对于不同路况，算法均具有较好的实时性和鲁棒性。

Design and Implementation of the Integrative Validation Platform for Flight Test Instruments System

With the explosive development of avionics and computer network technology, the complication and validation cost for Flight Test Instruments (FTI)) system is on the increase. In this paper, the FTI system validation procedure is analyzed, and the FTI integrative validation technology is researched. Otherwise, an integrative validation platform is designed and implemented with data acquiring, recording, real-time checking, data analyzing, health monitoring and etc. Besides, this validation platform is applied to flight test very well. The practical application shows that this platform can meet the factual task requirements and can reduce the validation periods and costs for FTI system, so it has good application value.
