定位导航信息与图像信息融合的便携式数字拍摄系统, 它主要包含便携式 数字拍摄装置和将获取的定位信息显示到该便携式数字拍摄装置的显示屏上的 定位信息接收机。 在拍摄时, 还可将定位信息接收机接收到的定位信息存储、 并将定位信息一同显示到该便携式数字拍摄装置的图像上。 该定位信息接收机 有 GPS接收机功能、 北斗接收机功能、伽利略接收机功能或其它地面定位接收 机功能。 该便携式数字拍摄装置可以是便携式数码相机或便携式数码摄像机。
请参阅图 1 , 它是定位导航信息与图像信息融合的便携式数字拍摄系统的 第一实施例图。 在便携式数码照相机或数码摄像机成像图的基础上, 加入定位 导航的功能。 我们可以使用功能比较强大的数字图像信息与定位数据信息的数 字信号处理器控制器芯片, 同时进行一体化综合数据信息融合处理, 将处理后 含有定位、 导航、 时间、 地图信息与图像信息全部及部分内容的一体化图像的 数据信息存储在容量较大的寄存器中, 然后通过信息数据接口电路输出。
这里以定位导航信息与图像信息融合的便携式数字拍摄系统中的融合处理 的一体化集成为实施例加以说明。 在一体化集成时, 便携式数字拍摄装置的摄 影头 bl l传感器采集的光信号, 经过光电变换电路和模拟处理的图像信号处理 电路 bl2, 通过模数转换 bl3变换为数字信号, 再经过数据压缩扩展 M4电路, 传输到便携式数字拍摄装置与定位信息接收机共用的定位解算及图像数字信号 处理器 abcl中。 定位信息接收机的天线 al l将接收到的射频定位信息信号, 射 频前端 al2的下变频的混频、 滤波、 放大之后, 通过模数转换 al3变换为数字 信号, 然后再接收信号相关器 al4中进行相关运算, 与定位解算及图像数字信 号处理器 abcl —同实现信号的捕获、 跟踪、 定位解算。 之后信号处理控制器 abcl对定位解算及图像数字信号进行融合处理, 将一体化信息存入一体化定位 与图像数据寄存器 abl5中, 并通过装置的信息数据接口电路 bl7输出, 同时可 以通过显示器 Μ8, 对其融合信息进行显示成像。
在其具体应用时, 结合利用定位信息数据与电子地图部分信息, 构成地点 特征信息显示于图像上的有特点的内容。 定位信息数据与电子地图部分信息中 的数据信息图像结合, 选取最能反映包含摄影定位场所的名称或摄影定位场所 附近最具代表性特征的名称信息, 自动与图像信息进行一体化综合数据信息融 合处理, 嵌入到图像中。 例如在北京天安门广场附近拍摄时, 在显示器上和存 入图片中, 除了显示时间、 经纬度之外, 配合电子地图信息, 显示出 "天安门 广场"的字样。 现有的手机、携带数码照相机或数码摄像机并不具备这种功能。

在系统装置中, 为了做到定位信息与图像信息的准确融合, 需要在整个系 统信号控制和处理时, 对时间和时序同步做出规定。 充分利用定位信息接收机 比较高精度的定时功能,在定位信息接收机中常带有精确时间输出端口,即 lpps 端口数据。 利用 lpps作为时间同步时钟, 对整个装置的相关部件和电路进行同 步控制和信号处理, 在图像信息中比较准确的嵌入时间和地点信息。
在一些特殊场合, 如警察、 勘探等部门应用时, 定位导航信息与图像信息 融合的便携式数字拍摄系统记录下的内容不希望被修订和改变, 为此在定位导 航信息与便携式数字拍摄装置的定位解算及图像信息数字信号处理器中对其融 合处理进行加密, 防止对写入到影像信息当中的位置、 时间、 地点信息进行修 改。
这种定位信息与图像信息融合的便携式数字拍摄装置包括但不限于以下融 合处理三个要素单元: 第一, 该装置的定位解算及图像信息数字信号处理器; 第二, 该装置的信息一体化的数据寄存器; 第三, 该装置的接口电路。
