【摘要】:自動(dòng)目標(biāo)識(shí)別(ATR)在機(jī)器人導(dǎo)航、智能交通監(jiān)控、輔助駕駛等領(lǐng)域得到了越來(lái)越多的應(yīng)用,同時(shí)為了滿(mǎn)足不同應(yīng)用的需求,ATR算法也越來(lái)越豐富。不同的處理算法往往需要不同的處理結(jié)構(gòu),因此建立一個(gè)通用的、配置靈活、可擴(kuò)展性強(qiáng)的面向ATR評(píng)估的操作系統(tǒng)平臺(tái)的需求也越來(lái)越強(qiáng)烈。同時(shí)隨著應(yīng)用的豐富,操作系統(tǒng)實(shí)時(shí)性方面的需求也越來(lái)越引起人們的注意。眾多國(guó)內(nèi)外專(zhuān)家和學(xué)者在這些方面已經(jīng)研究了多年并取得了較為客觀的成果,本文主要在前人研究工作的基礎(chǔ)上,完成了如下方面的設(shè)計(jì)和實(shí)現(xiàn): (1)根據(jù)自動(dòng)目標(biāo)識(shí)別的特點(diǎn),設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)較為通用的操作系統(tǒng)平臺(tái)。此操作系統(tǒng)平臺(tái)可以根據(jù)硬件系統(tǒng)的特點(diǎn)進(jìn)行適當(dāng)?shù)牟眉粢赃m應(yīng)不同的任務(wù)要求,同時(shí)由于系統(tǒng)采用結(jié)構(gòu)化設(shè)計(jì)使得系統(tǒng)具有較好的可擴(kuò)展性能。實(shí)驗(yàn)表明此系統(tǒng)能適應(yīng)大多數(shù)自動(dòng)目標(biāo)識(shí)別任務(wù)的要求。 (2)針對(duì)實(shí)時(shí)系統(tǒng)的特點(diǎn),對(duì)Linux的實(shí)時(shí)性進(jìn)行了初步的研究,,并且通過(guò)對(duì)Linux的改進(jìn)使得ARM端的控制系統(tǒng)能較好地保證部分自動(dòng)目標(biāo)識(shí)別任務(wù)(如智能視頻監(jiān)控)在實(shí)時(shí)性方面的需求。 (3)為了調(diào)用不同處理器來(lái)協(xié)同完成自動(dòng)目標(biāo)識(shí)別方面的任務(wù),同時(shí)為了保證各個(gè)模塊間的低耦合,處理器間的通信是個(gè)重要環(huán)節(jié)。本系統(tǒng)針對(duì)自動(dòng)目標(biāo)識(shí)別的特點(diǎn),設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)結(jié)構(gòu)簡(jiǎn)單,功能靈活的處理器通信模塊。不同處理器上的模塊通過(guò)此模塊來(lái)組合成不同的結(jié)構(gòu),從而保證了系統(tǒng)整體的靈活性。 (4)監(jiān)控軟件平臺(tái)的設(shè)計(jì)與實(shí)現(xiàn);谇懊娴难芯抗ぷ鳎覀儗(shí)現(xiàn)了一個(gè)集成多種功能的軟件平臺(tái),該軟件監(jiān)控整個(gè)硬件系統(tǒng),并對(duì)異常狀況做出適當(dāng)反應(yīng),同時(shí)根據(jù)不同處理器的特點(diǎn)為其分配不同的任務(wù)代碼,將離線分析和在線加載結(jié)合起來(lái)。
[Abstract]:Automatic target recognition (ATR) has been applied more and more in the fields of robot navigation, intelligent traffic monitoring, auxiliary driving and so on. At the same time, in order to meet the needs of different applications, ATR algorithm is becoming more and more abundant. Different processing algorithms often require different processing structures, so the need to establish a general, flexible and scalable operating system platform for ATR evaluation is becoming more and more intense. At the same time, with the rich application, the real-time requirements of the operating system are attracting more and more attention. Many domestic and foreign experts and scholars have studied these aspects for many years and have achieved more objective results. The design and implementation of the following aspects are completed: 1) according to the characteristics of automatic target recognition, a general operating system platform is designed and implemented. The operating system platform can be tailored according to the characteristics of the hardware system to adapt to different tasks, and the system has good scalability because of the structural design of the system. Experiments show that the system can meet the requirements of most automatic target recognition tasks. And through the improvement of Linux, the arm control system can better meet the real-time requirements of some automatic target recognition tasks (such as intelligent video surveillance). Complete the task of automatic target recognition, At the same time, the communication between processors is an important link in order to ensure the low coupling between the various modules. According to the characteristics of automatic target recognition, a simple structure and flexible processor communication module is designed and implemented in this system. The modules on different processors are combined into different structures to ensure the overall flexibility of the system. 4) the design and implementation of the monitoring software platform. Based on the previous research work, we have implemented a multi-functional software platform, which monitors the whole hardware system and responds appropriately to the abnormal situation. According to the characteristics of different processors, different task codes are assigned, and offline analysis and online loading are combined.
