附图说明
为了更清楚地说明本发明实施例的技术方案,下面将对实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其它的附图。
图1为本发明实施例提供的一种点阵本交互方法的流程示意图;
图2为本发明实施例提供的一种点阵本编码示意图;
图3为本发明实施例提供的另一种点阵本编码示意图;
图4为本发明实施例提供的另一种点阵本编码示意图。
具体实施方式
下面结合附图对本发明实施例进行详细描述。
应当明确,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
参见图1,本公开实施例提供了一种点阵本交互方法,包括如下步骤:
S101,用户书写之前先用智能笔点击封皮页,封皮页的局部和整页铺设有第一点阵码,智能笔通过镜头成像解析出其携带的二进制信息即封皮码信息,将其发送给智能终端;
S102,智能终端根据该封皮码信息与后台的数据库进行匹配,获取到与所述封皮码对应的笔记信息;
S103,智能笔在点阵本的内页进行书写,所述点阵本的内页铺设有第二点阵码,所述智能笔在内页书写的过程中,将识别到的书写点的坐标信息发送给智能终端;
S104,智能终端根据书写点的页码和坐标信息,将书写点绘制在该封皮码对应的笔记信息页面中。
在实现步骤S101~S104的过程中,用户书写之前先用智能笔点击封皮页,封皮页的局部和整页铺设有第一点阵码,智能笔通过镜头成像解析出其携带的二进制信息即封皮码信息,将其发送给智能终端;智能终端根据该封皮码信息与后台的数据库进行匹配,可以获取到与该封皮码对应的笔记信息。智能笔在点阵本内页进行书写,点阵本的内页铺设有第二点阵码,并将书写点的坐标信息发送给智能终端。智能终端根据书写点的页码和坐标信息,将书写点绘制在该封皮码对应的笔记信息页面中。
参见图2及图3,点阵本的内页码点方案设计可以用4X4的码点文件,水平方向和垂直方向各布5个栅格点,构成4X4的方块格,每个方格里面有一个标识方向的数据点,每个数据点有上、下、左、右、左上、左下、右上、右下8个方向。16个数据点中,其中一个点做校验点,每个数据点出现的位置有8个,可以附带3bit数据。15个数据点产生45bit的数据。本发明中内页每个点阵单元数据的定义如下:0-7Y轴坐标、8-15X轴坐标、16-25页码信息、26-27奇偶校验、28-45容错处理。
参见图4,封皮码的设计本发明采用的封皮码与内页码类似,区别点在于:数据点仅包含四个方向,用2位来表示。16个数据点总共对应32位数据,选其中三个点作为定向定位点(如14、15、16),所以有26bit的数据可用做封皮序列码,理论上有67108864页,即67108864种封皮。定向定位点在32位数据中对应的位置26~31位。其中,30和31位为奇偶校验位,所有的奇数位1、3、5…29加起来是奇数,则其中一位就是1,所有的偶数位0、2、4、6…28加起来是偶数,则其中一位就是0,30、31位合起来就是10。26~29为固定值,比如0000,此时需要在点阵内页码中将包含这个固定值的码值去除,防止冲突。
智能笔的镜头在捕捉到黑点信息之后,先判断14、15这两个固定点的位置是否与预设的定向定位点相符,如果是,则判断当前识别的是封皮,则根据封皮的编码方式解析出26位二进制数,并对其进行奇偶校验,如果奇偶校验通过则发送给智能终端;否则,则按照内页的编码方式进行解析,解析出X坐标、Y坐标和页码信息,发送给智能终端。
此外,还可以在后台对26位封皮码信息进行定义,包含批次信息、厂商信息、学校信息等。智能终端根据封皮码信息可以监控到每个批次的本子的使用情况。
需要注意的是,这种结合方式还可以应用在其他的领域,比如,不同批次同一科目的试题可以采用在局部铺设第二点阵码的方式来进行区分。
根据本公开实施例的一种具体实现方式,所述点阵本内页采用采用4×4的码点文件,水平方向和垂直方向各布5个栅格点,构成4×4的方块格,每个方格里面有一个标识方向的数据点,每个数据点有上、下、左、右、左上、左下、右上、右下8个方向;
在内页码点中包含的16数据点中,其中一个点做校验点,每个数据点出现的位置有8个,用于附带3bit数据,15个数据点产生45bit的数据。
根据本公开实施例的一种具体实现方式,内页每个点阵单元数据的定义如下:0-7 Y轴坐标、8-15 X轴坐标、16-25页码信息、26-27奇偶校验、28-45容错处理。

Claims (8)

  1. 一种点阵本交互方法,其特征在于,包括:
    用户书写之前先用智能笔点击封皮页,封皮页的局部和整页铺设有第一点阵码,智能笔通过镜头成像解析出其携带的二进制信息即封皮码信息,将其发送给智能终端;
    智能终端根据该封皮码信息与后台的数据库进行匹配,获取到与所述封皮码对应的笔记信息;
    智能笔在点阵本的内页进行书写,所述点阵本的内页铺设有第二点阵码,所述智能笔在内页书写的过程中,将识别到的书写点的坐标信息发送给智能终端;
    智能终端根据书写点的页码和坐标信息,将书写点绘制在该封皮码对应的笔记信息页面中。
  2. 根据权利要求1所述的点阵本交互方法,其特征在于,
    所述点阵本内页采用采用4×4的码点文件,水平方向和垂直方向各布5个栅格点,构成4×4的方块格,每个方格里面有一个标识方向的数据点,每个数据点有上、下、左、右、左上、左下、右上、右下8个方向;
    在内页码点中包含的16数据点中,其中一个点做校验点,每个数据点出现的位置有8个,用于附带3bit数据,15个数据点产生45bit的数据。
  3. 根据权利要求2所述的点阵本交互方法,其特征在于,
    内页每个点阵单元数据的定义如下:0-7Y轴坐标、8-15X轴坐标、16-25页码信息、26-27奇偶校验、28-45容错处理。
  4. 根据权利要求3所述的点阵本交互方法,其特征在于,
    所述点阵本的封皮码中,数据点仅包含四个方向,用2位来表示,16个数据点总共对应32位数据,选其中三个点作为定向定位点,有26bit的数据用做封皮序列码。
  5. 根据权利要求4所述的点阵本交互方法,其特征在于,
    所述点阵本的封皮码职工,定向定位点在32位数据中对应的位置26~31位,其中,30和31位为奇偶校验位,所有的奇数位1、3、5…29加起来是奇数,则其中一位就是1,所有的偶数位0、2、4、6…28加起来是偶数,则其中一位就是0,30、31位合起来是10。
  6. 根据权利要求5所述的点阵本交互方法,其特征在于,所述方法还包括:
    智能笔的镜头在捕捉到黑点信息之后,先判断14、15这两个固定点的位置是否与预设的定向定位点相符,如果是,则判断当前识别的是封皮,则根据封皮的编码方式解析出26位二进制数,并对其进行奇偶校验,如果奇偶校验通过则发送给智能终端;否则,则按照内页的编码方式进行解析,解析出X坐标、Y坐标和页码信息,发送给智能终端。
  7. 根据权利要求6所述的点阵本交互方法,其特征在于,所述方法还包括:
    在后台对26位封皮码信息进行定义,包含批次信息、厂商信息、学校信息,智能终端根据封皮码信息监控到每个批次的本子的使用情况。
  8. 根据权利要求6所述的点阵本交互方法,其特征在于,所述方法还包括:
    针对所述点阵本,采用在局部铺设第二点阵码的方式来区分不同批次同一科目的试题。
