实施例1
根据本发明实施例，提供了一种像素数据确定方法的实施例，需要说明的是，在 附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图1是根据本发明实施例的像素数据确定方法的流程图，如图1所示，该方法包括如下步骤：
步骤S102，发送像素数据采集指令至线扫传感器，其中，线扫传感器中包括并行排布的三个感光芯片，三个感光芯片分别对应三种颜色，像素数据采集指令用于使位于不同位置处的三个感光芯片分别扫描对应的像素行；
在本申请所记载的步骤S102中，通过发送像素数据采集指令至线扫传感器，能够使得素数据采集指令用于使位于不同位置处的三个感光芯片分别扫描对应的像素行。假设在像素为3*3的图像中，第一位置感光芯片扫描第一行3个像素点的像素数据，第二位置感光芯片扫描第二行3个像素点的像素数据，第三位置感光芯片扫描第三行3个像素点的像素数据，达到了每个感光芯片扫描与之正对应位置处的像素行，使得像素行中像素确定的数据更为准确。
作为一种可选的实施例，三个感光芯片，包括：蓝光感光芯片，绿光感光芯片，红光感光芯片。在该实施例中，蓝光感光芯片能够获取B像素数据，绿光感光芯片能够获取G像素数据，红光感光芯片能够获取R像素数据，即如上述的例子，假设蓝光感光芯片，绿光感光芯片，红光感光芯片分别位于第一位置、第二位置、第三位置。第一位置感光芯片，即蓝色感光芯片扫描第一行3个像素点的B像素数据，第二位置感光芯片，即绿色感光芯片扫描第二行3个像素点的G像素数据，第三位置感光芯片，即红色感光芯片扫描第三行3个像素点的R像素数据。
步骤S104，接收线扫传感器发送的与目标像素行对应的第一感光像素数据，其中，第一感光像素数据为第一位置感光芯片扫描出的感光像素数据，在获取与目标像素行对应的第一感光像素数据时，目标像素行与第一位置感光芯片的扫描位置对应；
在本申请所记载的步骤S104中，在获取与目标像素行对应的第一感光像素数据时，目标像素行与第一位置感光芯片的扫描位置对应，使得得到的第一感光像素数据是出于与第一位置感光芯片的扫描位置对应的位置处的，能够准确扫描得到第一感光像素数据。
步骤S106，循环依次发送移动预定像素行指令与像素数据采集指令至线扫传感器，直至接收到线扫传感器发送的与目标像素行对应的第二感光像素数据与第三感光像素数据，其中，第二感光像素数据为第二位置感光芯片扫描出的感光像素数据，第三感光像素数据为第三位置感光芯片扫描出的感光像素数据，在获取与目标像素行对应的 第二感光像素数据时，目标像素行与第二位置感光芯片的扫描位置对应，在获取与目标像素行对应的第三感光像素数据时，目标像素行与第三位置感光芯片的扫描位置对应：
在本申请所记载的步骤S106中，通过该步骤，能够通过移动线扫传感器，获取目标像素行全部的像素数据，即第一感光像素数据，第二感光像素数据，第三感光像素数据，使得第一感光像素数据，第二感光像素数据，第三感光像素数据都是被处于正对应位置处的第一位置感光芯片，第二位置感光芯片，第三位置感光芯片分别扫描得到的。
步骤S108，依据与线扫传感器对应的颜色校正系数，与目标像素行对应的第一感光像素数据、第二感光像素数据与第三感光像素数据，确定目标像素行对应的目标像素数据。
在本申请所记载的步骤S108中，通过该步骤，获取了颜色校正系数参与了校正，使用相关技术中获取像素数据的方法获取像素数据，并依据颜色校正系数进行校正时，会出现色彩边缘现象。因此，通过该步骤，能够消除在颜色校正系数的参与下，出现色彩边缘现象的问题。而且，通过颜色校正系数，能够校正像素数据，使得最终确定出的目标像素数据能够还原更真实的色彩。
通过上述步骤，发送像素数据采集指令至线扫传感器，其中，线扫传感器中包括并行排布的三个感光芯片，三个感光芯片分别对应三种颜色，像素数据采集指令用于使位于不同位置处的三个感光芯片分别扫描对应的像素行，接收线扫传感器发送的与目标像素行对应的第一感光像素数据，再循环依次发送移动预定像素行指令与像素数据采集指令至线扫传感器，直至接收到线扫传感器发送的与目标像素行对应的第二感光像素数据与第三感光像素数据，其中，第一感光像素数据为第一位置感光芯片扫描出的感光像素数据，在获取与目标像素行对应的第一感光像素数据时，目标像素行与第一位置感光芯片的扫描位置对应，第二感光像素数据为第二位置感光芯片扫描出的感光像素数据，第三感光像素数据为第三位置感光芯片扫描出的感光像素数据，在获取与目标像素行对应的第二感光像素数据时，目标像素行与第二位置感光芯片的扫描位置对应，在获取与目标像素行对应的第三感光像素数据时，目标像素行与第三位置感光芯片的扫描位置对应。依据与线扫传感器对应的颜色校正系数，与目标像素行对应的第一感光像素数据、第二感光像素数据与第三感光像素数据，确定目标像素行对应的目标像素数据。即目标像素行的像素数据是经过多次扫描，分别依据第一位置感光芯片，第二位置感光芯片与第三位置感光芯片扫描确定出的，是在确定的扫描位置扫描得到的，相对于相关技术中，目标像素行的像素数据由一次扫描，扫描出全部的像素数据，颜色校正系数校正后，可能会存在色彩边缘的问题。在确定的扫描位置扫 描得到对应的像素数据，使得确定出的像素数据的区域范围都是规范的，相对应的，确定出的像素数据是更准确的，即不会出现色彩边缘的问题，进而解决了相关技术中确定出目标像素行对应的目标像素数据时，目标像素数据会存在彩色边缘的技术问题。
作为一种可选的实施例，发送像素数据采集指令至线扫传感器之前，还包括：获取线扫传感器扫描被扫描物体的扫描区域；依据扫描区域，确定扫描传感器的初始扫描位置；发送位置调节指令至线扫传感器，其中，位置调节指令携带有初始扫描位置。
在该实施例中，当线扫传感器要扫描一个被扫描物体时，是能够确定出包括这个被扫描物体的扫描区域的。依据这个扫描区域，确定出扫描传感器的初始扫描位置，发送位置调节指令至线扫传感器，使得线扫传感器响应于位置调节指令到达初始扫描位置，以便完成整个扫描区域的图像处理。
作为一种可选的实施例，依据与目标像素行对应的第一感光像素数据、第二感光像素数据与第三感光像素数据，确定目标像素行对应的目标像素数据之后，还包括：依据扫描区域，确定扫描传感器的终点扫描位置；确定初始扫描位置至终点扫描位置所经过的所有像素行；循环依次发送移动预定像素行指令与像素数据采集指令至线扫传感器，直至接收到线扫传感器发送的与所有像素行分别对应的第一感光像素数据，第二感光像素数据与第三感光像素数据；依据与所有像素行分别对应的第一感光像素数据，第二感光像素数据与第三感光像素数据，确定与扫描区域对应的图像数据。
在该实施例中，获取扫描区域所有像素行的像素数据，以确定出与扫描区域对应的图像数据。可以理解的为，移动线扫传感器，相当于也移动了三个感光芯片的位置，控制三个感光芯片分别扫描与之对应的三行像素，得到对应的像素值，直至接收到线扫传感器发送的与所有像素行分别对应的第一感光像素数据，第二感光像素数据与第三感光像素数据，能够确定出最终的图像数据，使得最终确定出的图像不存在色彩边缘的问题。
作为一种可选的实施例，发送像素数据采集指令至线扫传感器之前，还包括：确定移动像素行；依据移动像素行，确定像素数据采集指令与移动预定像素行指令。
在该实施例中，像素数据采集指令采集的像素行数以及移动预定像素行所移动的像素行数都是可以根据实际的应用与场景确定的。即可以确定出想要多少像素行，便依据移动像素行，确定像素数据采集指令与移动预定像素行指令。例如，若目标移动一个像素的长度，则移动像素行为1，像素数据采集指令采集的像素行数定为1以及移动预定像素行所移动的像素行数定为1，即感光芯片扫描的像素行为1行，移动预定像素行为1行；若目标移动两个像素的长度，则移动像素行为2，像素数据采集指令采集的像素行数定为2以及移动预定像素行所移动的像素行数定为1，即感光芯片 扫描的像素行为2行，移动预定像素行为1行。通过进行不同的设置，可以满足不同应用与场景的需求，扩大本申请的保护范围。
作为一种可选的实施例，确定目标移动距离，包括：获取目标分辨率；依据目标分辨率，确定目标移动像素行。
在该实施例中，公开了一种确定目标移动距离的方法，例如，高分辨率当做降低一半的分辨率像素使用时，如600DPI(Dots Per Inch，每英寸点数)当做300DPI的分辨率用时，移动长度就会由原来的43.2um(同上述一个像素的长度)，变为84.6um(同上述二个像素的长度)，即移动像素行由1变成了2，此时，像素数据采集指令采集的像素行数由1变成了2，即可以完成像素的采集。使得本申请所提供的方法可以根据不同的分辨率进行调整，增加了本方案的适用性。
作为一种可选的实施例，依据与线扫传感器对应的颜色校正系数，与目标像素行对应的第一感光像素数据、第二感光像素数据与第三感光像素数据，确定目标像素行对应的目标像素数据之前，包括：获取与线扫传感器对应的颜色校正系数。
在该实施例中，获取了颜色校正系数，能够消除在颜色校正系数的参与下，出现色彩边缘现象的问题。而且，通过颜色校正系数，能够校正像素数据，使得最终确定出的目标像素数据能够还原更真实的色彩。
基于上述实施例及可选实施例，提供了一种可选实施方式，下面具体说明。
本发明可选实施方式中提供了一种像素数据确定方法，以线扫传感器为蓝绿红三排感光芯片并行排布的线扫传感器，即蓝色感光芯片处于第一位置，绿色感光芯片处于第二位置，红色感光芯片处于第三位置为例，线扫传感器的蓝绿红三排感光芯片为B，G，R，一次曝光可以获得三行像素数据分别是，第一位置处对应行的蓝光的像素数据，第二位置处对应行的绿光的像素数据，第三位置处对应的红光的像素数据，通过本发明可选实施方式提供的方法能够准确地确定出像素点的像素信息，消除像素行之间存在的色彩边缘现象。
图2是现有技术中像素点的示意图，每个像素点都是由红绿蓝三种颜色光孔组成的。本发明可选实施方式提供的像素数据确定方法将分三次曝光(同上述扫描)，获取如图2中一行像素点的全部像素数据。
现有技术中直接将(B1，G1，R1)×颜色校正系数后形成的图像会有彩色边缘现象出现。图3是本发明可选实施方式提供的使用本方法后的图像示意图，如图3所示，采用了该技术后，将(B1，G2，R3)×颜色校正系数后形成图像，扫描过程中，彩色边缘现象消失。下面对本发明可选实施方式进行详细介绍：
S1，获取线扫传感器扫描被扫描物体的扫描区域；
S2，依据扫描区域，确定扫描传感器的初始扫描位置；
S3，发送位置调节指令至线扫传感器，使线扫传感器移至初始扫描位置，即使得蓝光感光芯片能够扫描到第一行的像素点；
S4，发送像素数据采集指令至线扫传感器，使线扫传感器曝光扫描，获得第一行的像素数据，定义成B1，即此时第一行的像素点的B1像素数据，由于蓝色感光芯片位于第一位置刚能够扫描到第一行的像素点，因此，位于蓝色感光芯片之后的绿色感光芯片与红色感光芯片是无法得到像素点的像素数据的；
S5，发送移动预定像素行指令与像素数据采集指令至线扫传感器，使得线扫传感器向预定方位移动一行，使线扫传感器曝光扫描，获得第一行的像素数据G2，以及第二行的像素数据B2；
S6，再次发送移动预定像素行指令与像素数据采集指令至线扫传感器，使得线扫传感器向预定方位再移动一行，使线扫传感器曝光扫描，获得第一行的像素数据R3，以及第二行的像素数据G3，以及第三行的像素数据B3；
需要说明的是，图4是本发明可选实施方式中的像素数据确定示意图，如图4所示，图4中即示出了上述第一行像素点的(B1，G2，R3)像素数据的确定过程，图中深色部分即为上述(B1，G2，R3)像素数据。
…
S7，直至接收到线扫传感器发送的与所有像素行分别对应的像素数据B，像素数据G与像素数据R；
S8，依据颜色校正系数，与所有像素行对应的像素数据B，像素数据G与像素数据R，确定与扫描区域对应的图像数据。
需要说明的是，在上述过程中，确定与扫描区域对应的图像数据，可以是依据颜色校正系数，与每像素行对应的像素数据B，像素数据G与像素数据R，确定每像素行对应的目标像素数据的，例如，对于第一行中的某个像素点来说，第一行像素点的像素数据为(B1，G2，R3)，乘以颜色校正系数。等到一个颜色校正后的彩色像素点。以此类推第N，N+1，N+2次曝光获得的像素点也以同样算法做颜色校正。
可选地，基于上述可选实施方式，本申请又提出来一种高分辨率换算成低分辨率用的扩展方案，图5是本发明可选实施方式的扩展方案中的像素数据确定示意图，如图5所示，图5中即示出了下述(B1，G1，R2)像素数据的确定过程，图中深色部分即 为上述(B1，G1，R2)像素数据，下面对本方案进行具体说明：
由于高分辨率换算成低分辨率用，所以原来高分辨率时的两个像素点：像素1的第一行B1，像素2的第一行B1，像素1的上行G，像素2的上行G四个像素点，组成1个新的低分辨率像素点。假设从扫描区域的中间位置开始扫描，扫描方向从像素点中的B运动到R时，对于一种蓝绿红三排感光芯片依次排列的线扫相机，获得三种颜色的图像数据可以分两次曝光的。第一次曝光获得红光的图像数据定义为R1，蓝光的图像数据B1。当移动到1/2line时开始第二次曝光获得绿光的图像数据G1；当移动到1line时，曝光获得像素数据R2，B2；将(B1，G1，R2)×颜色校正系数＝红绿蓝R，G，B三色灰度值合成彩色点作为第一行彩色像素点。以此类推第N，N+1，N+2次曝光获得的像素点也以同样算法做颜色校正。以此类推第N，N+1，N+2次曝光获得的像素点也以同样算法做颜色校正。
通过上述可选实施方式，可以达到至少以下的有益效果：目标像素行的像素数据是经过多次扫描，分别由第不同位置处的感光芯片扫描确定出的，是在确定的扫描位置扫描得到的，相对于相关技术中，目标像素行的像素数据由一次扫描，扫描出全部的像素数据，可能会存在色彩边缘的问题。在确定的扫描位置扫描得到对应的像素数据，使得确定出的像素数据的区域范围都是规范的，相对应的，确定出的像素数据是更准确的，即不会出现色彩边缘的问题，进而解决了相关技术中确定出目标像素行对应的目标像素数据时，目标像素数据会存在彩色边缘的技术问题。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，因为依据本发明，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本发明所必须的。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例的方法。

工业实用性
本申请实施例提供的方案可应用于图像处理领域，在本申请实施例中，发送像素数据采集指令至线扫传感器，其中，线扫传感器中包括并行排布的三个感光芯片，三个感光芯片分别对应三种颜色，像素数据采集指令用于使位于不同位置处的三个感光芯片分别扫描对应的像素行，接收线扫传感器发送的与目标像素行对应的第一感光像 素数据，再循环依次发送移动预定像素行指令与像素数据采集指令至线扫传感器，直至接收到线扫传感器发送的与目标像素行对应的第二感光像素数据与第三感光像素数据，其中，第一感光像素数据为第一位置感光芯片扫描出的感光像素数据，在获取与目标像素行对应的第一感光像素数据时，目标像素行与第一位置感光芯片的扫描位置对应，第二感光像素数据为第二位置感光芯片扫描出的感光像素数据，第三感光像素数据为第三位置感光芯片扫描出的感光像素数据，在获取与目标像素行对应的第二感光像素数据时，目标像素行与第二位置感光芯片的扫描位置对应，在获取与目标像素行对应的第三感光像素数据时，目标像素行与第三位置感光芯片的扫描位置对应。依据与线扫传感器对应的颜色校正系数，与目标像素行对应的第一感光像素数据、第二感光像素数据与第三感光像素数据，确定目标像素行对应的目标像素数据。即目标像素行的像素数据是经过多次扫描，分别依据第一位置感光芯片，第二位置感光芯片与第三位置感光芯片扫描确定出的，是在确定的扫描位置扫描得到的，相对于相关技术中，目标像素行的像素数据由一次扫描，扫描出全部的像素数据，颜色校正系数校正后，可能会存在色彩边缘的问题。在确定的扫描位置扫描得到对应的像素数据，使得确定出的像素数据的区域范围都是规范的，相对应的，确定出的像素数据是更准确的，即不会出现色彩边缘的问题，进而解决了相关技术中确定出目标像素行对应的目标像素数据时，目标像素数据会存在彩色边缘的技术问题。
