【摘要】：目標(biāo)跟蹤技術(shù)是電視導(dǎo)引頭的關(guān)鍵技術(shù),同時也是計算機視覺等領(lǐng)域的研究熱點。本文的主要研究內(nèi)容為低成本電視導(dǎo)引頭的目標(biāo)跟蹤器以及導(dǎo)航信息的隨屏顯示技術(shù)。主要進行了以下工作： 首先設(shè)計了基于單片機、字符疊加器和DSP芯片TMS320DM642的目標(biāo)跟蹤和隨屏顯示系統(tǒng)的硬件平臺。其中,DM642作為核心處理器來實現(xiàn)圖像跟蹤算法,單片機和專用的字符疊加芯片用來實現(xiàn)導(dǎo)航信息的隨屏顯示。 然后,對相關(guān)匹配跟蹤算法進行了研究,并將其應(yīng)用在DM642上,完成了基于DM642的視頻采集與顯示程序、圖像跟蹤程序以及UART串口數(shù)據(jù)傳輸?shù)瘸绦蛟O(shè)計。為實現(xiàn)目標(biāo)位置、跟蹤狀態(tài)、跟蹤框和十字線等導(dǎo)航信息的實時隨屏顯示,設(shè)計了用于導(dǎo)航信息的專用字庫、單片機和字符疊加器的SPI通信程序、串口通信程序以及導(dǎo)航信息隨屏疊加程序等軟件。 最后,對系統(tǒng)硬件平臺的各功能模塊進行了測試。通過對一個運動的模型小車做圖像跟蹤實驗,驗證了系統(tǒng)的可行性。實驗結(jié)果表明,本文中設(shè)計的目標(biāo)跟蹤和隨屏顯示系統(tǒng)能夠正確完成目標(biāo)跟蹤以及導(dǎo)航信息隨屏顯示工作,為低成本電視導(dǎo)引頭的工程應(yīng)用打下了基礎(chǔ)。
[Abstract]:Target tracking is the key technology of TV seeker. At the same time, it is also a research hotspot in computer vision. The main content of this paper is the target tracker of low cost TV seeker and the display technology of navigation information. The main work is as follows:. Firstly, the hardware platform of target tracking and display with screen system based on single chip microcomputer, character superposition and DSP chip TMS320DM642 is designed, in which DM642 is used as the core processor to realize image tracking algorithm. Single-chip microcomputer and special character superposition chip are used to display navigation information with screen. Then, the correlation matching tracking algorithm is studied, and it is applied to DM642. The video acquisition and display program based on DM642, image tracking program and UART serial port data transmission program are completed. Tracking status, real-time display of navigation information such as tracking frame and cross line, design of special font library for navigation information, SPI communication program of single chip computer and character superposition, etc. Serial communication program and navigation information with screen superposition program and other software. Finally, the functional modules of the hardware platform of the system are tested, and the feasibility of the system is verified by an image tracking experiment of a moving model car. The target tracking and on-screen display system designed in this paper can correctly complete the target tracking and navigation information display with the screen, which lays the foundation for the engineering application of low-cost TV seeker.
