| 摘 要: 为了更好的解决无人车定点追踪的问题，本文提出了一种基于OpenCL的图像追踪算法。特定目标物的检 测和连续跟踪技术是目前计算机视觉领域的前沿方向和热点研究[1]。本设计是将OpenCV中的CamShift算法移植到DE1- SoC开发板的OpenCL平台上。整个设计分为五个模块：视频模块、音频模块、超声波测距模块、蓝牙音箱驱动模块 和算法移植模块。最终小车能够实现定点追踪固定目标物，且在目标物的正前方10cm处停下同时外接蓝牙音箱响起乐 曲。 |

| Abstract: In order to solve the problem of unmanned vechicle tracking,this paper proposes an image tracking algorithm based on OpenCL.The detection and continuous tracking of a certain object is the leading direction and hot spot in the field of computer vision.This design is the CamShift algorithm in the OpenCV transplanted to the OpenCL for DE1-SoC. The whole design is divided into five modules:video module,audio module,ultrasonic distance measuring module,bluetooth speaker driver module and algorithm transplantation module.Finally our car can achieve fixed-point tracking fixed target,and then stop in front of the target 10cm and at the same time to pick up the bluetooth speaker. |
