When the conveying device 13 drives the entire area of the ticket or the preset partial area to pass the scanning position of the image sensor 141, the image sensor 141 completes the acquisition of the plurality of first images, wherein each of the first images corresponds to a light source, such as When the white light illuminator 1411a illuminates the ticket, the first image acquired is a white light reflection image of the ticket, and when the transmission image white light source 17a illuminates the ticket, the collected first image is a white light transmission image of the ticket.

本实施例中，票据的设定区域可以为票据的全部区域，也可以为票据的部分区域，相应地，第一图像可以为票据的全部区域的图像，也可以为票据的部分区域的图像。比如，一种可选实施例中，第二距离L2和第五距离L5的值均为0，也即，票据的扫描起始位置为票据的前沿，票据的扫描终止位置为票据的后沿，这种情况下，当完成票据扫描时，获取到的第一图像为票据的全部区域的图像；再比如，另一种可选实施例中，第二距离L2和第五距离L5中至少一项的值不为0，这种情况下，当完成票据扫描时，获取到的第一图像为票据的部分区域的图像。考虑到第一图像的亮度可能不满足要求，为提高票据图像获取效率，可以是第一图像为票据的部分区域的图像。In this embodiment, the setting area of the ticket may be the entire area of the ticket, or may be a partial area of the ticket. Accordingly, the first image may be an image of the entire area of the ticket, or may be an image of a partial area of the ticket. For example, in an optional embodiment, the values of the second distance L2 and the fifth distance L5 are both 0, that is, the scanning start position of the ticket is the leading edge of the ticket, and the scanning termination position of the ticket is the trailing edge of the ticket. In this case, when the ticket scanning is completed, the acquired first image is an image of the entire area of the ticket; and, in another alternative embodiment, at least one of the second distance L2 and the fifth distance L5. The value is not 0. In this case, when the ticket scanning is completed, the acquired first image is an image of a partial area of the ticket. In view of the fact that the brightness of the first image may not satisfy the requirement, in order to improve the ticket image acquisition efficiency, the first image may be an image of a partial region of the ticket.

在S420中，判断第一图像的亮度是否满足预设要求。In S420, it is determined whether the brightness of the first image satisfies a preset requirement.

本步骤中，设置有预设亮度要求，判断第一图像的亮度是否满足该预设亮度要求。可选地，预设亮度要求包括图像亮度与票据图像的预设标准亮度之间的差值在预设范围内，例如，该预设范围可以是票据图像的预设标准亮度的20％，比如，获取第一图像后，计算第一图像的亮度，当该第一图像的亮度与票据图像的预设标准亮度的差值与票据图像的预设标准亮度的比值小于20％时，判定第一图像的亮度满足要求，否则，判定第一图像的亮度不满足要求。In this step, a preset brightness requirement is set, and it is determined whether the brightness of the first image satisfies the preset brightness requirement. Optionally, the preset brightness requirement includes a difference between the image brightness and the preset standard brightness of the ticket image within a preset range, for example, the preset range may be 20% of the preset standard brightness of the ticket image, for example, After obtaining the first image, calculating the brightness of the first image, determining that the ratio of the difference between the brightness of the first image and the preset standard brightness of the ticket image and the preset standard brightness of the ticket image is less than 20% The brightness of the image satisfies the requirement, otherwise, it is determined that the brightness of the first image does not satisfy the requirement.

预设亮度要求还可以是包括图像亮度在预设范围内，该预设范围可以是预设的数值范围，比如，获取第一图像后，计算第一图像的亮度，当第一图像的亮度在预设的数值范围内时，判定第一图像的亮度满足要求，当第一图像的亮度不在预设的数值范围内时，判定第一图像的亮度不满足要求。The preset brightness requirement may further include: the image brightness is within a preset range, and the preset range may be a preset value range. For example, after acquiring the first image, calculating the brightness of the first image, when the brightness of the first image is When the preset value range is within, it is determined that the brightness of the first image satisfies the requirement, when the first image is bright When the degree is not within the preset numerical range, it is determined that the brightness of the first image does not satisfy the requirement.

一种可选实施例中，计算第一图像中所有像素点的亮度的均值，并将所有像素点的亮度的均值作为第一图像的亮度值，另一种可选实施例中，计算第一图像中所有像素点的亮度的方差，并将所有像素点的亮度的方差作为第一图像的亮度值。票据图像的预设标准亮度可以采用与计算第一图像的亮度值相同的运算方法，如计算均值或者计算方差，对作为模板的票据图像进行计算得到。In an optional embodiment, the average value of the brightness of all the pixels in the first image is calculated, and the average value of the brightness of all the pixels is used as the brightness value of the first image. In another alternative embodiment, the first calculation is performed. The variance of the luminance of all the pixels in the image, and the variance of the luminance of all the pixels is taken as the luminance value of the first image. The preset standard brightness of the ticket image may be calculated by the same calculation method as calculating the brightness value of the first image, such as calculating the mean value or calculating the variance, and calculating the ticket image as a template.

当在步骤S410中，票据的设定区域为票据的部分区域时，票据图像获取装置扫描作为模板的票据的相同部分区域的图像，按照与计算第一图像的亮度值相同的运算方法计算作为模板的票据的相同部分区域的图像的亮度值，并将该亮度值作为票据图像的预设标准亮度。当在步骤S410中，票据的设定区域为票据的全部区域时，票据图像获取装置扫描作为模板的票据的全部区域的图像，按照与计算第一图像的亮度值相同的运算方法计算作为模板的票据的全部区域的图像的亮度值，并将该亮度值作为票据图像的预设标准亮度。When the set area of the ticket is a partial area of the ticket in step S410, the ticket image acquiring means scans the image of the same partial area of the ticket as the template, and calculates it as a template according to the same calculation method as calculating the brightness value of the first image. The brightness value of the image of the same partial area of the ticket, and the brightness value is used as the preset standard brightness of the ticket image. When the setting area of the ticket is the entire area of the ticket in step S410, the ticket image acquiring means scans the image of the entire area of the ticket as the template, and calculates the same as the calculation method of the brightness value of the first image. The brightness value of the image of the entire area of the ticket, and the brightness value is used as the preset standard brightness of the ticket image.

当对票据进行扫描后获取到多幅第一图像时，依次判断每幅第一图像的亮度是否满足要求。可以是包括：对于任意一幅第一图像，均计算其亮度值，并判断该亮度值是否满足上述的预设亮度要求。比如，票据图像获取装置根据每幅第一图像的设定光源和对应的票据区域预先存储有与每幅第一图像对应的预设标准亮度。票据图像获取装置计算每幅第一图像的亮度，判断每幅第一图像的亮度与该第一图像对应的预设标准亮度的差值是否处于预设的差值范围内，或者每幅第一图像的亮度与该第一图像对应的预设标准亮度的差值与该预设标准亮度的比值是否小于预设阈值，或者每幅第一图像的亮度是否处于预设的数值范围内，当任意一幅第一图像不满足上述的预设亮度要求时，确定该第一图像的亮度不满足要求。When a plurality of first images are acquired after scanning the ticket, it is sequentially determined whether the brightness of each of the first images satisfies the requirement. The method may include: calculating, for any one of the first images, a brightness value thereof, and determining whether the brightness value meets the preset brightness requirement. For example, the bill image obtaining means pre-stores a preset standard brightness corresponding to each of the first images in accordance with the set light source of each of the first images and the corresponding ticket area. The bill image obtaining device calculates the brightness of each of the first images, and determines whether the difference between the brightness of each of the first images and the preset standard brightness corresponding to the first image is within a preset difference range, or each of the first Whether the ratio of the difference between the brightness of the image and the preset standard brightness corresponding to the first image and the preset standard brightness is less than a preset threshold, or whether the brightness of each first image is within a preset value range, when When a first image does not satisfy the preset brightness requirement, it is determined that the brightness of the first image does not meet the requirement.

在S430中，若第一图像的亮度不满足预设要求，则根据预设要求以及第一图像的亮度，调整与图像亮度相关的扫描参数，以使使用调整后的扫描参数扫描得到的图像满足预设要求。In S430, if the brightness of the first image does not meet the preset requirement, the scan parameter related to the brightness of the image is adjusted according to the preset requirement and the brightness of the first image, so that the image scanned by using the adjusted scan parameter is satisfied. Preset requirements.

本步骤中采用以下方法调整与图像亮度相关的扫描参数：将第一图像的亮度与预设标准亮度进行对比分析，得到扫描参数调整值，根据扫描参数调整值调整与图像亮度相关的扫描参数，其中，与图像亮度相关的扫描参数可以为第一图像对应的光源的发光时间或者光电流的值，对应地，根据扫描参数调整值调整与图像亮度相关的扫描参数，可以为：根据扫描参数调整值调整第一图像对应的光源的发光时间或者光电流的值。In this step, the following method is used to adjust the scanning parameters related to the brightness of the image: comparing the brightness of the first image with the preset standard brightness, obtaining the scanning parameter adjustment value, and adjusting the scanning parameter related to the image brightness according to the scanning parameter adjustment value, The scan parameter related to the brightness of the image may be the light-emitting time or the value of the light current of the light source corresponding to the first image, and correspondingly, the value is adjusted according to the scan parameter. Adjusting the scan parameter related to the brightness of the image may be: adjusting the light-emitting time or the value of the light current of the light source corresponding to the first image according to the scan parameter adjustment value.

可选的，将所述第一图像的亮度与预设标准亮度进行对比分析，得到扫描参数调整值，包括：根据所述第一图像的亮度与所述预设标准亮度的比例关系或所述第一图像的亮度与所述预设标准亮度的差值，计算得到所述扫描参数调整值。Optionally, the brightness of the first image is compared with the preset standard brightness to obtain a scan parameter adjustment value, including: according to a ratio of the brightness of the first image to the preset standard brightness or the The difference between the brightness of the first image and the preset standard brightness is calculated to obtain the scan parameter adjustment value.

比如，当第一图像的亮度为A1，票据图像的预设标准亮度为A时，设置扫描参数调整值为k1＝A/A1，将第一图像对应的设定光源的发光时间调整为当前值的k1倍，或者，将第一图像对应的设定光源的光电流的值调整为当前值的k1倍。For example, when the brightness of the first image is A1 and the preset standard brightness of the ticket image is A, the scan parameter adjustment value is set to k1=A/A1, and the illumination time of the set light source corresponding to the first image is adjusted to the current value. K1 times, or the value of the photocurrent of the set light source corresponding to the first image is adjusted to be k1 times the current value.

可选的，将所述第一图像的亮度与预设标准亮度进行对比分析，得到扫描参数调整值，还可以是包括：根据所述第一图像的亮度与所述预设标准亮度的比例关系或所述第一图像的亮度与所述预设标准亮度的差值，通过查询预先存储的对照表得到所述扫描参数调整值。Optionally, the brightness of the first image is compared with the preset standard brightness to obtain a scan parameter adjustment value, and the method further includes: determining, according to a brightness relationship between the brightness of the first image and the preset standard brightness Or the difference between the brightness of the first image and the preset standard brightness, and the scan parameter adjustment value is obtained by querying a pre-stored comparison table.

比如，当第一图像的亮度为A2，票据图像的预设标准亮度为A3时，根据亮度差值A2-A3在预先存储的差值对照表内查找该差值对应的扫描参数调整值k2，将第一图像对应的设定光源的发光时间调整为当前值的k2倍，或者，将第一图像对应的设定光源的光电流的值调整为当前值的k2倍。For example, when the brightness of the first image is A2 and the preset standard brightness of the ticket image is A3, the scan parameter adjustment value k2 corresponding to the difference is searched according to the difference value A2-A3 in the pre-stored difference table. The light-emitting time of the set light source corresponding to the first image is adjusted to be k2 times the current value, or the value of the light current of the set light source corresponding to the first image is adjusted to be k2 times the current value.

以图1中的票据图像获取装置为例，控制器11在步骤S420中计算第一图像的亮度，并获取预先存储的票据图像的预设标准亮度，当控制器11通过步骤S420确定第一图像的亮度不满足要求时，通过本步骤根据第一图像的亮度以及票据图像的预设标准亮度计算扫描参数调整值，并根据扫描参数调整值调整第一图像对应的光源的发光时间或者光电流的值，比如，当第一图像对应的设定光源为白光发光器1411a，并计算得到扫描参数调整值为k1时，控制器11将存储器15中存储的第一预设时间的值修改为当前值的k1倍，或者，控制器11调整输出至与白光发光器1411a连接的DA转换器的控制信号，将白光发光器1411a的光电流的值调整为当前值的k1倍。Taking the ticket image acquiring device in FIG. 1 as an example, the controller 11 calculates the brightness of the first image in step S420, and acquires a preset standard brightness of the pre-stored ticket image, when the controller 11 determines the first image through step S420. When the brightness is not satisfactory, the scanning parameter adjustment value is calculated according to the brightness of the first image and the preset standard brightness of the ticket image, and the lighting time or the photocurrent of the light source corresponding to the first image is adjusted according to the scanning parameter adjustment value. For example, when the set light source corresponding to the first image is the white light illuminator 1411a and the scan parameter adjustment value is calculated as k1, the controller 11 modifies the value of the first preset time stored in the memory 15 to the current value. Alternatively, the controller 11 adjusts the control signal output to the DA converter connected to the white light emitter 1411a to adjust the value of the photocurrent of the white light emitter 1411a to k1 times the current value.

进一步地，当对票据进行扫描后获取到多幅第一图像时，将不满足预设亮度要求的第一图像的亮度与该第一图像对应的预设标准亮度进行对比分析，得到扫描参数调整值，根据扫描参数调整值调整该不满足预设亮度要求的第一图像对应的光源的发光时间或者光电流的值。 Further, when the plurality of first images are acquired after scanning the ticket, the brightness of the first image that does not meet the preset brightness requirement is compared with the preset standard brightness corresponding to the first image, and the scan parameter adjustment is obtained. And adjusting a value of the light-emitting time or the photocurrent of the light source corresponding to the first image that does not satisfy the preset brightness requirement according to the scan parameter adjustment value.

比如，当不满足预设亮度要求的第一图像的亮度为A1，与该第一图像的亮度对应的预设标准亮度为A时，设置扫描参数调整值为k＝A/A1，将该不满足预设亮度要求的第一图像对应的设定光源的发光时间调整为当前值的k倍，或者，将该设定光源的光电流的值调整为当前值的k倍。For example, when the brightness of the first image that does not meet the preset brightness requirement is A1, and the preset standard brightness corresponding to the brightness of the first image is A, the scan parameter adjustment value is set to k=A/A1, and the The illumination time of the set light source corresponding to the first image that satisfies the preset brightness requirement is adjusted to be k times of the current value, or the value of the photocurrent of the set light source is adjusted to be k times of the current value.

以图1中的票据图像获取装置为例，控制器11在步骤S420中计算每幅第一图像的亮度，并获取预先存储的每幅第一图像对应的预设标准亮度，当控制器11通过步骤S420确定一幅特定的第一图像不满足预设亮度要求时，通过本步骤根据该不满足预设亮度要求的第一图像的亮度以及与第一图像对应的预设标准亮度计算扫描参数调整值，并根据扫描参数调整值调整该不满足预设亮度要求的第一图像对应的光源的发光时间或者光电流的值，比如，该不满足预设亮度要求的第一图像对应的设定光源为红外光发光器1411b，并且计算得到扫描参数调整值为k1时，控制器11将存储器15中存储的第二预设时间修改为当前值的k1倍，或者，控制器11调整输出至与红外光发光器1411b连接的DA转换器的控制信号，将红外光发光器1411b的光电流的值调整为当前值的k1倍。Taking the ticket image acquiring device in FIG. 1 as an example, the controller 11 calculates the brightness of each first image in step S420, and acquires a preset standard brightness corresponding to each first image stored in advance, when the controller 11 passes Step S420: When it is determined that a specific first image does not meet the preset brightness requirement, the scan parameter adjustment is calculated according to the brightness of the first image that does not satisfy the preset brightness requirement and the preset standard brightness corresponding to the first image. And adjusting a value of the light-emitting time or the light current of the light source corresponding to the first image that does not meet the preset brightness requirement according to the scan parameter adjustment value, for example, the set light source corresponding to the first image that does not meet the preset brightness requirement When the infrared light illuminator 1411b is calculated and the scan parameter adjustment value is calculated as k1, the controller 11 modifies the second preset time stored in the memory 15 to k1 times the current value, or the controller 11 adjusts the output to the infrared The control signal of the DA converter connected to the photo illuminator 1411b adjusts the value of the photocurrent of the infrared illuminator 1411b to k1 times the current value.

本步骤中，由于将第一图像的亮度与票据图像的预设标准亮度进行对比，根据对比结果调整第一图像对应的光源的发光时间或者光电流的值，而票据图像的预设标准亮度满足要求，因此使用调整后的扫描参数重新扫描票据时，得到的图像的亮度也满足要求。In this step, since the brightness of the first image is compared with the preset standard brightness of the ticket image, the light-emitting time or the value of the light current of the light source corresponding to the first image is adjusted according to the comparison result, and the preset standard brightness of the ticket image is satisfied. It is required that the brightness of the resulting image also satisfies the requirements when the ticket is rescanned using the adjusted scan parameters.

步骤S440，使用调整后的扫描参数重新扫描票据，得到票据的第二图像。Step S440, re-scanning the ticket using the adjusted scan parameters to obtain a second image of the ticket.

考虑到如图2所示的票据图像获取装置的结构，本步骤的过程为：控制票据回退至设定位置，使用调整后的扫描参数对票据进行扫描，得到票据的第二图像，能够理解，由于第二图像使用调整后的扫描参数扫描得到，因此第二图像对应的光源与第一图像对应的光源相同。上述设定位置可以是图像传感器141的扫描位置，控制票据回退至设定位置可以是将票据的扫描起始位置回退至图像传感器141的扫描位置。Considering the structure of the ticket image acquiring device shown in FIG. 2, the process of this step is: controlling the ticket to fall back to the set position, and scanning the ticket using the adjusted scanning parameter to obtain a second image of the ticket, which can be understood. Since the second image is scanned using the adjusted scan parameters, the light source corresponding to the second image is the same as the light source corresponding to the first image. The set position may be a scan position of the image sensor 141, and the control ticket may be retracted to the set position by retracting the scan start position of the ticket to the scan position of the image sensor 141.

可选地，根据第一图像的亮度调整扫描参数后，控制器11控制输送装置13驱动票据沿后退方向移动，票据移动过程中，控制器11检测第二传感器162的状态，当检测到第二传感器162由被覆盖状态变化到不被覆盖状态时，判定票据的前沿到达第二传感器162的检测位置，此时，控制器11控制输送装置13驱动票据沿前进方向移动，并开始记录票据移动的距离，当所记录的票据移动的距离等于第三距离L3时，判定票据的扫描起始位置到达图像传感器141的扫描位置，此时，控制器11控制图像采集器14与输送装置13配合工作以启动扫描票据，从而获取票据的第二图像。Optionally, after adjusting the scan parameter according to the brightness of the first image, the controller 11 controls the transport device 13 to drive the ticket to move in the backward direction. During the movement of the ticket, the controller 11 detects the state of the second sensor 162, and when the second is detected When the sensor 162 changes from the covered state to the uncovered state, it is determined that the leading edge of the ticket reaches the detection position of the second sensor 162. At this time, the controller 11 controls the conveying device 13 to drive the ticket to move in the forward direction, and starts recording the movement of the ticket. Distance, when the recorded ticket moves distance, etc. At the third distance L3, it is determined that the scan start position of the ticket reaches the scan position of the image sensor 141. At this time, the controller 11 controls the image collector 14 to cooperate with the transport device 13 to start scanning the ticket, thereby acquiring the second ticket. image.

可选地，当步骤S410中对票据进行扫描后获取到多幅第一图像时，如果判定多幅第一图像中一幅特定的第一图像的亮度不能满足预设亮度要求，则根据不能满足预设亮度要求的第一图像的亮度调整相应的扫描参数，并使用调整后的扫描参数重新扫描票据，以获取票据的第二图像。其中，当多幅第一图像的亮度不满足要求时，本步骤中分别使用调整后的与每幅第一图像对应的扫描参数重新扫描票据，得到多幅第二图像，其中，一幅第二图像与一幅亮度不满足要求的第一图像相对应，当多幅第一图像中仅有一幅第一图像的亮度不满足要求，本步骤中使用调整后的与该第一图像对应的扫描参数重新扫描票据，得到一幅第二图像，该第二图像与亮度不满足要求的第一图像对应。比如，步骤S410中对票据进行扫描后获取到的多幅第一图像分别为票据的白光反射图像、红外光反射图像、紫外光反射图像、白光透射图像、红外光透射图像、紫外光透射图像等六幅图像时，如果在步骤S420中判定白光反射图像的亮度不满足预设亮度要求，本步骤中，根据白光反射图像的亮度与白光反射图像对应的预设标准亮度的差值计算与白光反射图像对应的扫描参数调整值，并根据计算的扫描参数调整值调整白光反射图像对应的扫描参数，在重新扫描票据时，获取到第二图像，该第二图像为票据的白光反射图像。Optionally, when the plurality of first images are acquired after scanning the ticket in step S410, if it is determined that the brightness of a particular first image in the plurality of first images cannot meet the preset brightness requirement, the The brightness of the first image required by the preset brightness adjusts the corresponding scan parameter, and the ticket is re-scanned using the adjusted scan parameter to obtain the second image of the ticket. Wherein, when the brightness of the plurality of first images does not meet the requirement, in the step, the adjusted scan parameters corresponding to each of the first images are used to re-scan the ticket respectively to obtain a plurality of second images, wherein one second The image corresponds to a first image whose brightness does not meet the requirement. When only one of the plurality of first images has a brightness that does not meet the requirement, the adjusted scan parameter corresponding to the first image is used in this step. The ticket is rescanned to obtain a second image corresponding to the first image whose brightness does not satisfy the requirement. For example, the plurality of first images acquired after scanning the ticket in step S410 are respectively a white light reflection image, an infrared light reflection image, an ultraviolet light reflection image, a white light transmission image, an infrared light transmission image, an ultraviolet light transmission image, and the like. In the case of six images, if it is determined in step S420 that the brightness of the white light reflection image does not satisfy the preset brightness requirement, in this step, the difference between the brightness of the white light reflection image and the preset standard brightness corresponding to the white light reflection image is calculated and reflected by the white light. The scan parameter adjustment value corresponding to the image is adjusted, and the scan parameter corresponding to the white light reflection image is adjusted according to the calculated scan parameter adjustment value. When the ticket is rescanned, the second image is acquired, and the second image is a white light reflection image of the ticket.

本步骤中，还能够将票据由输送通道的出口送出输送通道，并提示用户再次将票据放入输送通道的入口，当检测到票据进入输送通道的入口时，再次对票据进行扫描，得到第二图像。In this step, the ticket can also be sent out of the delivery channel by the outlet of the conveying channel, and the user is prompted to put the ticket into the entrance of the conveying channel again. When the ticket is detected to enter the entrance of the conveying channel, the ticket is scanned again to obtain the second. image.

以图1中的票据图像获取装置为例，控制器11检测到票据扫描完毕后，控制输送装置13驱动票据沿前进方向继续移动，直至将票据由输送通道的出口送出输送通道。票据图像获取装置向用户发出再次放入票据的提示信息，比如，通过通信装置12向主机返回“将票据再次送入输送通道”，当用户接收到主机输出的提示信息时，将票据再次放入输送通道的入口，当控制器11检测到票据再次进入输送通道时，控制输送装置13和图像采集器14配合工作以重新扫描票据，得到第二图像。Taking the ticket image acquiring device in FIG. 1 as an example, after the controller 11 detects that the ticket scanning is completed, the control conveying device 13 drives the ticket to continue moving in the forward direction until the ticket is sent out of the conveying channel by the outlet of the conveying channel. The bill image obtaining device sends a prompt message to the user to re-enter the bill. For example, the communication device 12 returns a “return ticket to the transport channel” to the host. When the user receives the prompt information output by the host, the ticket is placed again. At the entrance of the delivery channel, when the controller 11 detects that the ticket has again entered the delivery channel, the control delivery device 13 and the image capture device 14 cooperate to rescan the ticket to obtain a second image.

本实施例的票据图像获取方法中，当获取到票据的第一图像后，判断第一图像的亮度是否满足要求，若第一图像的亮度不满足要求，根据第一图像的亮度调整与图像亮度相关的扫描参数，并重新扫描票据，获取票据的第二图像。通过本实施例的票据图像获取方法，当由于票据类型发生变化导致获取的票据的第一图像的亮度不满足要求时，可以根据第一图像的亮度调整与图像亮度相关的扫描参数，由于使用调整后的扫描参数扫描得到的图像满足要求，因此重新扫描票据后获取的票据的第二图像的亮度满足要求，从而有效解决相关技术的票据图像获取装置在获取不同类型的票据的图像时，存在获取到的票据图像不能满足要求的问题。In the ticket image acquiring method of this embodiment, after acquiring the first image of the ticket, determining the first Whether the brightness of the image satisfies the requirement, if the brightness of the first image does not satisfy the requirement, the scanning parameter related to the brightness of the image is adjusted according to the brightness of the first image, and the ticket is re-scanned to obtain the second image of the ticket. With the ticket image obtaining method of the embodiment, when the brightness of the first image of the acquired ticket is not satisfied due to the change of the ticket type, the scanning parameter related to the image brightness may be adjusted according to the brightness of the first image, The image obtained by scanning the scanning parameter satisfies the requirement, so that the brightness of the second image of the ticket acquired after the re-scanning of the ticket satisfies the requirement, thereby effectively solving the problem that the ticket image acquiring device of the related art acquires an image of a different type of ticket. The image of the ticket arrived does not meet the required problem.
