具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，如果不冲突，本申请实施例中的各个特征可以相互组合，均在本申请的保护范围之内。另外，虽然在装置示意图中进行了功能模块的划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置示意图中的模块划分，或流程图中的顺序执行所示出或描述的步骤。
实施例一
如图1所示为一种扫描成像方法的流程示意图。扫描成像方法可以应用于计算机设备，计算机设备例如可以包括相机、扫描仪、个人计算机、服务器计算机、手持设备或便携式设备、平板型设备、多处理器系统、基于微处理器的系统、可编程的消费计算机设备、网络PC、小型计算机、大型计算机等。
示例性的，扫描成像方法应用于搭载线阵相机的扫描仪，例如数字切片扫描仪，用于实现通过线阵相机扫描目标物，如切片标本等，得到目标物的扫描图像等过程。
示例性的，线阵相机可以与扫描仪一体化设置,如线阵相机可以内嵌入扫描仪，或者线阵相机可以与扫描仪可拆卸的连接。
在本说明实施例中，不限制线阵相机的类型，线阵相机例如可以包括二线(2lines)线阵相机、三线(3lines)线阵相机等多线线阵相机、TDI(time delay integration，时间延时积分)线阵相机，多片式线阵相机等。
示例性的，扫描成像方法可以应用于线阵相机的处理器和/或扫描仪的处理器。
如图1所示，扫描成像方法包括以下步骤S110至步骤S150。
步骤S110、获取线阵相机沿第一方向扫描目标物时的第一扫描数据。
如图2所示，以由上至下为第一方向。可以理解的，当然也可以以由下至上为第一方向、以由左至右为第一方向、以由右至左为第一方向等等，本说明书对此不做限制。
示例性的，扫描仪包括运动机构，运动机构可以载着线阵相机移动，或者运动机构可以载着放置目标物的载台移动，或者分别载着线阵相机和放置目标物的载台移动。本说明书实施例以运动机构载着线阵相机移动实现线阵相机和目标物相对运动为例进行说明。
在一些可行的实施方式中，所述线阵相机的图像传感器包括多个相互平行的像素带，各所述像素带的延伸方向均与所述第一方向垂直。
为便于说明，本说明书以三线阵相机为例进行说明。在其他一些实施方式中，线阵相机也可以为二线阵相机、TDI线阵相机、多片式线阵相机等。
如图3所示，图像传感器包括三个相互平行的像素带。当第一方向为竖直方向时，各所述像素带的延伸方向为横向。
具体的，多个所述像素带各自感应不同波长范围的光线，例如像素带可以感应红外光、红色光、蓝色光、绿色光、紫外光等各种波长的光。
如图3所示，三个像素带分别感应红色光、蓝色光和绿色光。可以理解的，图像传感器的多个像素带当然也可以感应其他波长范围的光线，相邻像素带之间的间隔也可以为其他的数值、或者不同波长范围像素带的排序也可以不同，本说明书对此不做限制。
示例性的，多个所述像素带相邻设置，或者间隔特定的距离设置。
可以理解的，当多个所述像素带间隔特定的距离设置时，可以防止其他波长范围的光线的干扰，提高扫描成像的质量。
如图3所示，图像传感器扫描到目标物的图示区域时，通过红色光的像素带获取该区域中与所述红色光的像素带对应位置的红色通道数据，通过蓝色光的像素带获取该区域中与所述蓝色光的像素带对应位置的蓝色通道数据，通过绿色光的像素带获取该区域中与所述绿色光的像素带对应位置的绿色通道数据。
示例性的，所述第一扫描数据包括多个第一通道数据，所述多个第一通道数据各自通过对应的像素带获取。
如图4所示为步骤S110获取线阵相机沿第一方向扫描目标物时的第一扫描数据的示意图。
在T1时刻至T6时刻，图像传感器扫描到目标物的不同区域，各像素带在不同时刻扫描的位置也不同。在每一时刻均可获取与像素带数目一致的第一通道数据，例如每一时刻可以获取不同位置的红色通道数据R、蓝色通道数据B、绿色通道数据G。
如图4所示，经过多个时刻，可以获取同一位置的红色通道数据、蓝色通道数据、绿色通道数据。例如在T1时刻获取的绿色通道数据G1，在T3时刻获取的蓝色通道数据B3、在T5时刻获取的红色通道数据R5对应于目标物的同一位置。
步骤S120、根据所述第一方向对应的校正规则对所述第一扫描数据进行校正处理，得到第一图像。
示例性的，步骤S120中所述根据所述第一方向对应的校正规则对所述第一扫描数据进行校正处理，得到第一图像，包括：根据对应于目标物同一位置的多个第一通道数据确定所述位置的图像。
其中，所述同一位置的多个第一通道数据是在所述线阵相机沿所述第一方向扫描目标物的不同时刻获取的。
由于三线阵相机RGB通道排布在空间上是有差异的，这就导致在同一时刻拍摄到的RGB通道对应的是不同位置的图像。如图4所示，在T1时刻获取到红色通道数据R1，蓝色通道数据B1，绿色通道数据G1的像素数据，当按照扫描方向到T3时刻，此时的蓝色通道数据B3才和绿色通道数据G1是空间上同一处的图像数据，同理到T5时刻，此时的红色通道数据R5和蓝色通道数据B3，绿色通道数据G1是空间上同一处的图像数据。
示例性的，可以在扫描过程中分别缓冲3个时刻的蓝色通道数据，5个时刻的红色通道数据，在不断更新缓冲数据的同时，可以结合缓冲数据的时刻或存 储位置对齐绿、蓝、红三个通道的数据，最终获得无色差的第一图像。
可以理解的，可以根据图像传感器的具体结构设置相应的校正规则，例如，当图像传感器的多个像素带感应不同波长范围的光线，相邻像素带之间具有其他间隔、或者不同波长范围像素带的排序不同时，扫描过程中缓冲各种波长范围对应的通道数据的数目可以适应性调整；即以上举例的目的为便于说明本实施例的一种实现方式，不应作为对本说明书实施例的限定。
示例性的，步骤S120中所述根据所述第一方向对应的校正规则对所述第一扫描数据进行校正处理，得到第一图像，包括：基于所述第一方向对应的校正规则，根据各所述第一通道数据的获取时间确定目标物同一位置的多个第一通道数据，以及根据所述多个第一通道数据确定所述位置的图像。
示例性的，校正规则包括红色通道数据、蓝色通道数据、绿色通道数据在空间位置上偏差的行数，或者包括红色通道数据、蓝色通道数据、绿色通道数据的获取时刻的偏差。
示例性的，校正规则可以通过一个校准过程来确定，该校准过程可以通过算法实现，也可以通过手动设定。例如，由于线阵相机图像传感器的像素加工等因素，红色通道数据、蓝色通道数据、绿色通道数据在空间位置上偏差的行数不一定为整数，这个行数可以通过该校准过程来确定。
如图4所示，目标物同一位置的红色通道数据和绿色通道数据差了5行，蓝色通道数据和绿色通道数据差了3行，那么在校正过程中，可以缓存5行红色通道数据，3行蓝色通道数据，在T5时刻的时候将同一空间位置的通道数据进行对齐处理，之后的扫描校正过程是个循环处理的过程。
可以理解的，第一方向对应的校正规则可以根据线阵相机所使用的图像传感器的种类、规格等进行适应性调整，在此不做赘述。
步骤S130、获取所述线阵相机沿第二方向扫描目标物时的第二扫描数据。
具体的，所述第一方向和所述第二方向的夹角为180度。
如图2所示，当第一方向为由上至下的方向时，第二方向为由下至上的方向。
具体的，线阵相机在沿第一方向扫描目标物时的姿态和沿第二方向扫描目标物时的姿态相同。示例性的，如图3所示，沿第一方向扫描目标物时，线阵相机图像传感器三个像素带由上至下的排列顺序为：红色光的像素带、蓝色光的像素带、绿色光的像素带；如图5所示，沿第二方向扫描目标物时，线阵相机图像传感器三个像素带由上至下的排列顺序也保持为：红色光的像素带、蓝色光的像素带、绿色光的像素带。
如图5所示，图像传感器扫描到目标物的图示区域时，通过红色光的像素带获取该区域中与所述红色光的像素带对应位置的红色通道数据，通过蓝色光的像素带获取该区域中与所述蓝色光的像素带对应位置的蓝色通道数据，通过绿色光的像素带获取该区域中与所述绿色光的像素带对应位置的绿色通道数据。
示例性的，所述第二扫描数据包括多个第二通道数据，所述多个第二通道数据各自通过对应的像素带获取。
如图6所示为步骤S130获取线阵相机沿第二方向扫描目标物时的第二扫描数据的示意图。
在T1时刻至T6时刻，图像传感器扫描到目标物的不同区域，各像素带在不同时刻扫描的位置也不同。在每一时刻均可获取与像素带数目一致的第一通道数据，例如每一时刻可以获取不同位置的红色通道数据R、蓝色通道数据B、绿色通道数据G。
如图6所示，经过多个时刻，可以获取同一位置的红色通道数据、蓝色通 道数据、绿色通道数据。例如在T1时刻获取的红色通道数据R1，在T3时刻获取的蓝色通道数据B3、在T5时刻获取的绿色通道数据G5对应于目标物的同一位置。
步骤S140、根据所述第二方向对应的校正规则对所述第二扫描数据进行校正处理，得到第二图像。
示例性的，步骤S140中所述根据所述第二方向对应的校正规则对所述第二扫描数据进行校正处理，得到第二图像，包括：根据对应于目标物同一位置的多个第二通道数据确定所述位置的图像。
其中，所述同一位置的多个第二通道数据是在所述线阵相机沿所述第二方向扫描目标物的不同时刻获取的。
由于三线阵相机RGB通道排布在空间上是有差异的，这就导致在同一时刻拍摄到的RGB通道对应的是不同位置的图像。如图6所示，在T1时刻获取到红色通道数据R1，蓝色通道数据B1，绿色通道数据G1的像素数据，当按照扫描方向到T3时刻，此时的蓝色通道数据B3才和红色通道数据R1是空间上同一处的图像数据，同理到T5时刻，此时的绿色通道数据G5和蓝色通道数据B3，红色通道数据R1是空间上同一处的图像数据。
示例性的，在扫描过程中分别缓冲3个时刻的蓝色通道数据，5个时刻的绿色通道数据，在不断更新缓冲数据的同时，可以结合缓冲数据的时刻或存储位置对齐绿、蓝、红三个通道的数据，最终获得无色差的第一图像。
示例性的，步骤S140中所述根据所述第二方向对应的校正规则对所述第二扫描数据进行校正处理，得到第二图像，包括：基于所述第二方向对应的校正规则，根据各所述第二通道数据的获取时间确定目标物同一位置的多个第二通道数据，以及根据所述多个第二通道数据确定所述位置的图像。
示例性的，校正规则包括红色通道数据、蓝色通道数据、绿色通道数据在空间位置上偏差的行数，或者包括红色通道数据、蓝色通道数据、绿色通道数据的获取时刻的偏差。
如图6所示，目标物同一位置的绿色通道数据和红色通道数据差了5行，蓝色通道数据和红色通道数据差了3行，那么在校正过程中，可以缓存5行绿色通道数据，3行蓝色通道数据，在T5时刻的时候将同一空间位置的通道数据进行对齐处理，之后的扫描校正过程是个循环处理的过程。
可以理解的，第二方向对应的校正规则可以根据线阵相机所使用的图像传感器的种类、规格等进行适应性调整，在此不做赘述。
步骤S150、对所述第一图像和所述第二图像进行拼接处理，得到目标物的扫描图像。
示例性的，如图7所示，将多次沿第一方向扫描得到的多个第一图像和多次沿第二方向扫描得到的多个第二图像，根据扫描的顺序进行拼接处理，得到目标物整体的扫描图像。
在一些可行的实施方式中，所述扫描成像方法还包括：控制所述线阵相机或目标物的载台相对运动，使所述线阵相机交替对目标物进行沿所述第一方向的扫描和沿所述第二方向的扫描。
如图2所示，线阵相机在目标物的左侧先沿第一方向扫描目标物，然后沿第二方向扫描，之后再次沿第一方向扫描，以此交替完成对目标物整体的扫描。
在一些可行的实施方式中，所述扫描成像方法还包括：在所述线阵相机沿所述第一方向的扫描和/或沿所述第二方向的扫描完成后，控制所述线阵相机或目标物的载台沿第三方向相对运动预设的距离，所述第三方向与所述第一方向垂直。
示例性的，如图8所示为线阵相机相对目标物的移动轨迹示意图。图8中的1至8表示线阵相机移动轨迹的先后顺序。在线阵相机相对目标物沿所述第一方向的扫描完成后，向右侧移动预设的距离，然后沿所述第二方向进行扫描；在线阵相机相对目标物沿所述第二方向的扫描完成后，向右侧再次移动预设的距离，以沿第一方向进行扫描。
在一些实施方式中，也可以对目标物的同一列或同一行进行第一方向的扫描和第二方向的扫描，然后再对下一列或下一行进行第一方向的扫描和第二方向的扫描。示例性的，对某一列沿第一方向扫描时的第一扫描数据校正处理得到第一图像，对该列沿第二方向扫描时的第二扫描数据校正处理得到第二图像，将该列的第一图像和第二图像进行图像融合处理，可以得到该列较高精度的扫描图像，之后将目标物所有列的扫描图像拼接得到整体的扫描图像。
本申请实施例提供的扫描成像方法，可以通过获取线阵相机沿第一方向扫描目标物时的第一扫描数据，根据第一方向对应的校正规则对第一扫描数据进行校正处理，得到第一图像；以及获取线阵相机沿第二方向扫描目标物时的第二扫描数据；根据第二方向对应的校正规则对第二扫描数据进行校正处理，得到第二图像；之后对第一图像和第二图像进行拼接处理可以得到目标物的扫描图像。可以实现往复路径上的扫描，减少运动的空程，提高扫描效率，而且在扫描方向不同时，采用扫描方向对应的校正规则对扫描数据进行校正处理，提高扫描图像的质量。
示例性的，如图9所示，左侧为未进行相应校正处理时的扫描图像，右侧为本说明书实施例扫描成像方法得到的扫描图像，该扫描图像质量更高，消除了色差。具体的，图9中左侧扫描图像的左右两部分分别对应实施例中正反不同方向的扫描结果，两个结果拼接形成最终完整的图像，可以看出右半部分具 有比较明显的色差，图9中右侧扫描图像则不存在这种色差。
实施例二
请结合前述实施例参阅本实施例，如图10所示为本申请实施例提供的另一种扫描成像方法的流程示意图。
如图2所示，扫描成像方法包括以下步骤S210至步骤S240。
步骤S210、获取线阵相机沿第一方向扫描目标物时的第一图像。
在一些实施方式中,线阵相机自身可以获取线阵相机沿第一方向扫描目标物时的第一扫描数据,根据所述第一方向对应的校正规则对所述第一扫描数据进行校正处理，得到第一图像。可以理解的线阵相机预设有固定的扫描方向，可以将该扫描方向作为第一方向，相应的扫描相机可以输出校正后的第一图像。
具体的，第一方向的色彩校正可以由线阵相机自身实现，但相机内部设置的参数只能保证一个方向上的校正成功。如果使用线阵相机自带的色彩校正功能，则线阵相机在反向扫描目标物时生成的图像会存在较为严重的色彩畸变，如图9中左侧的扫描图像，此时的图像不可用。
步骤S220、获取所述线阵相机沿第二方向扫描目标物时的第二扫描数据。
示例性的，线阵相机沿第二方向扫描目标物时可以得到第二扫描数据。与线阵相机通信连接的计算机设备，如扫描仪、个人计算机、服务器计算机、手持设备或便携式设备、平板型设备等可以从线阵相机读取所述第二扫描数据。

步骤S230、根据所述第二方向对应的校正规则对所述第二扫描数据进行校正处理，得到第二图像。
示例性的，所述线阵相机的图像传感器包括多个相互平行的像素带，各所述像素带的延伸方向均与所述第一方向垂直。
示例性的，多个所述像素带各自感应不同波长范围的光线；所述第二扫描数据包括多个第二通道数据，所述多个第二通道数据各自通过对应的像素带获取。
示例性的，所述根据所述第二方向对应的校正规则对所述第二扫描数据进行校正处理，得到第二图像，包括：根据对应于目标物同一位置的多个第二通道数据确定所述位置的图像；其中，所述同一位置的多个第二通道数据是在所述线阵相机沿所述第二方向扫描目标物的不同时刻获取的。
示例性的，与线阵相机通信连接的计算机设备，如扫描仪、个人计算机、服务器计算机、手持设备或便携式设备、平板型设备等可以根据所述第二方向对应的校正规则对所述第二扫描数据进行校正处理，得到第二图像。
示例性的，所述根据所述第二方向对应的校正规则对所述第二扫描数据进行校正处理，得到第二图像，包括：基于所述第二方向对应的校正规则，根据各所述第二通道数据的获取时间确定目标物同一位置的多个第二通道数据，以及根据所述多个第二通道数据确定所述位置的图像。
步骤S240、对所述第一图像和所述第二图像进行拼接处理，得到目标物的扫描图像。
示例性的，与线阵相机通信连接的计算机设备可以对所述第一图像和所述 第二图像进行拼接处理，得到目标物的扫描图像。
步骤S220、S230和S240，分别对应实施例一中的S130、S140和S150，不再赘述。
本申请实施例提供的扫描成像方法，通过获取线阵相机沿默认的第一方向扫描目标物时得到的第一图像；以及获取线阵相机沿第二方向扫描目标物时的第二扫描数据；根据第二方向对应的校正规则对第二扫描数据进行校正处理，得到第二图像；之后对第一图像和第二图像进行拼接处理可以得到目标物的扫描图像。可以实现往复路径上的扫描，减少运动的空程，提高扫描效率，而且在扫描方向不同时，采用扫描方向对应的校正规则对扫描数据进行校正处理，提高扫描图像的质量。

一种计算机可读存储介质，所述计算机可读存储介质存储有计算机程序，若所述计算机程序被处理器执行，实现前述扫描成像方法的步骤。
本申请可用于众多通用或专用的计算系统环境或配置中。例如：相机、扫描仪、个人计算机、服务器计算机、手持设备或便携式设备、平板型设备、多处理器系统、基于微处理器的系统、可编程的消费计算机设备、网络PC、小型计算机、大型计算机、包括以上任何系统或设备的分布式计算环境等等，如实施例三。
