Description
技术领域
本发明属于目标跟踪技术领域,具体涉及一种对燃油型设备进行跟踪的方法。
背景技术
目前对于燃油型设备的跟踪主要是利用计算机视觉技术中的视频跟踪技术,通过在视频的每一帧中定位目标,以生成目标的型轨迹,并在每一时刻提供完整的目标区域。视频跟踪技术在军事和民用方面都有着十分广泛的应用,军事方面包括无人飞行器、精确制导、空中预警、战场监视等;民用方面包括移动机器人、智能视频监控、智能交通系统、人机交互、虚拟现实等。但当处于某些特殊情况之下,利用计算机视觉技术可能并不是最适合的跟踪方式。
发明内容
为解决上述现有技术中出现的问题,本发明提出了一种对燃油型设备进行跟踪的方法。
本发明所述的对燃油型设备进行跟踪的方法为:
(1)将荧光材料进行亲油改性;
(2)将改性后的荧光材料加入到燃油中;
(3)实时采集燃油燃烧后所产生的尾气颗粒物;
(4)利用激光诱导荧光的方法对尾气颗粒物进行检测,根据检测到的荧光数据来确定燃油型设备的轨迹,以此对燃油型设备进行跟踪。
所述荧光材料为稀土掺杂无机物光致发光材料。
所述荧光材料的组成包括激活剂和基质;所述激活剂为Eu3+、Ce3+、Tm3+中的一种或几种,基质为硅酸盐基质、氧化物基质、无机非金属盐基质、金属酸盐基质中的一种或几种。
所述荧光材料的耐高温和耐火程度应满足燃油型设备燃油过程中的燃烧温度条件,其经过燃烧后仍保持荧光性能。
所述燃烧温度条件为800-2200℃。
所述步骤(1)的具体操作为:将γ-(甲基丙烯酰氧基)丙基三甲氧基硅烷(KH-570)加入无水乙醇中,然后加入荧光材料,50-70℃回流搅拌反应10-20h,反应结束后真空抽滤,无水乙醇洗涤,最后冷冻干燥即得改性后的荧光材料。
所述步骤(2)中改性后的荧光材料的添加量为0.1-1.0g/L。
本发明首先对荧光材料进行改性,将KH-570以化学键方式结合在荧光材料表面形成有机包覆层,使荧光材料表面变为亲油性;然后加入燃油中,使其均匀分散,最后收集尾气排放出的颗粒物进行荧光检测,实现燃油型设备在快速移动中的跟踪。
附图说明
图1为本发明实施例1使用的实验装置示意图;
图2为本发明实施例1中10s时间收集颗粒物的滤膜;
图3为本发明实施例1中10s时间收集颗粒物的激发光谱;
图4为本发明实施例1中10s时间收集颗粒物的发射光谱;
图5为本发明实施例1中10s时间收集颗粒物的荧光成像;
图6为本发明实施例1中空滤膜的发射光谱;
图7为本发明实施例1中空滤膜的荧光成像。
具体实施方式
下面将通过具体实施方式结合附图对本发明进一步详细说明,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部实施例。基于本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
实施例1
(1)选择硼酸钇钆铕(Y,Gd)BO3:Eu3+作为荧光材料,该材料采用高温退火的方式合成,能够经受住1400℃以上的高温;首先对硼酸钇钆铕(Y,Gd)BO3:Eu3+荧光材料进行亲油改性:将1.0g的γ-(甲基丙烯酰氧基)丙基三甲氧基硅烷(KH-570)加入盛有80mL无水乙醇的三口烧瓶中,并加入5.0g硼酸钇钆铕(Y,Gd)BO3:Eu3+荧光材料,60℃恒温水浴回流搅拌下反应12h,反应结束后进行真空抽滤,并用无水乙醇洗涤三次,最后放入冷冻干燥箱中干燥24h后得到改性后的荧光材料;
(2)将步骤(1)改性后的荧光材料取出1.0g均匀分散于2000mL的3号航空煤油中,然后倒入如图1所示的实验装置的煤油喷灯中进行燃烧并收集,煤油喷灯燃烧过程温度可达800-1200℃;
(3)尾气颗粒物的收集过程为:如图1所示,将耐高温的石英管前端置于煤油喷灯喷口处收集尾气,石英管后端连接上贴了滤膜的真空抽滤器装置,真空抽滤器上面为密闭口,下面接着一个抽气泵,形成一个真空抽气体系,使得前端的尾气能快速进入石英管,并使尾气中的颗粒物收集于滤膜上。收集过程中等待喷口处火焰呈现均匀淡蓝色火焰的时候开始收集,收集过程中采取分段计时收集,收集时间分别为:90s、60s、30s、10s。最后将收集到颗粒物的滤膜放在贴好标签的培养皿里面保存,如图2为10s时间收集到尾气颗粒物的滤膜。
(4)对收集到的尾气颗粒物进行荧光光谱测试(PL)分析材料经过高温燃烧之后的激发、发射光谱,以及利用荧光成像来对尾气颗粒物进行分析,并加入了空白滤膜的发射光谱和荧光成像进行对比。通过最短时间10s收集到颗粒物的实验结果可看出,如图3激发光谱中收集的颗粒物在254nm处具有最强的激发峰,如图4在激发波长为254nm处的发射谱中611nm处拥有最强发射峰;此外通过该颗粒物的荧光成像可以看出其发光效果,如图5为激发波长在254nm处的荧光成像,发光颜色为红色,跟该材料的实际发光颜色相同,为了与空滤膜的荧光效果形成对比,添加了空滤膜的发射光谱和荧光成像,如图6为颗粒物在254nm激发波长下的发射光谱,可以看出其没有发射峰的出现,说明其不具有荧光发射光谱,通过如图7空滤膜的荧光成像也可以看出,254nm激发波长下,空滤膜不具有荧光成像效果;荧光成像图中左边为明场图,右边为暗场对比图。由此可根据此荧光光谱和荧光成像效果来实现对燃油型设备的跟踪。
以上所述仅为本发明的一种实施例而已,并非用于限定本发明的保护范围。尽管参照前述实施例对本发明进行了详细说明,对于本领域的技术人员来说,其依然可以对前述实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换。凡在本发明的构思前提下,所作的任何修改、改进等、均应包含在本发明的保护范围之内。
