图2是本发明实施例提供的投影手机的一种结构示意图；

具体实施方式
以下结合附图对本发明进行详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
如图1所示，本发明的实施例提供一种用于移动终端的物品显示方法，包括：
S11，获取目标物品的图片和参数信息；
S12，根据所述参数信息对所述图片进行图像处理；
S13，将经过图像处理后的图片投影到预设位置，以使所述目标物品的影像尺寸等于所述目标物品的实际尺寸。
本发明实施例提供的用于移动终端的物品显示方法，能够获取目标物品的图片和参数信息，并根据参数信息对图片进行图像处理，再将经过图像处理后的图片投影到预设位置，从而使得目标物品的影像尺寸等于该目标物品的实际尺寸。这样就能够将目标物品的一些简单的参数信息和示意性的图片中的信息相结合，使目标物品的影像信息更细致丰富，为用户提供关于目标物品的更多细节，同时，由于影像尺寸与目标物品的实际尺寸相同，用户能够直观感受到该目标物品放置在预设位置是否合适，从而为用户提供了非常方便准确的购物参考，大大提升了用户体验。
一般的，在一些商户提供的购物软件应用程序(App)中包括有较为丰富的商品图片和商品参数，那么在步骤S11中，就可以通过目标物品所在的应用程序获取该目标物品的图片和参数信息。当App中的图片或参数信息不够全面时，可选的，还可以根据目标物品的产品序号从互联网上获取相应的图片和参数信息。
由于图片拍摄或设计时，目标物品的长、宽、高，颜色、材质光感等都可能有不同程度的失真。这些失真在小图片中也许并不明显，用户也查看不清太多细节，但如果要将与实物等比例的影像投放出来，这些失真就可能会为用户提供不够准确的信息，影响用户的判断。为了改善这些失真情况，在步骤S12中，可以利用步骤S11中获取的参数信息对图片进行图像处理，以使图片能够包含目标物品的更多细节。
图像处理方法可以多种多样，可依据用户需求实现不同的效果。例如，在本发明的一个实施例中，根据所述参数信息对所述图片进行图像处理可以包括：
根据所述目标物品的长、宽、高信息对所述图片中目标物品的长、宽、高的比例进行调整；
形成不同视角下所述目标物品的视图。
也就是说，本实施例中，可以利用发达的图像处理技术，利用参数信息对目标物品的外形进行校正，还可以将原本一张或几张图片的内容进行整合，从而能够在不同角度查看目标物品，优选的，甚至还可以将图片处理成模拟三维立体图像的效果，为用户提供全方位的参考。
在步骤S13中，可以将经过图像处理后的图片投影到预设位置，该预设位置可以是目标物品预计摆设的位置，或者其他一些应用场景中，可选的，为了准确将目标物品的影像投放到预设位置，还可以在预设位置附近设置一定的参照物。例如，如果用户在浏览电商提供的电视机信息，想要看看某一型号的电视机放在家中客厅的电视柜上尺寸是否合适，颜色、样式与客厅里的其他设施搭配是否协调，那么他就可以选择电视柜为参照物。
然而，仅仅将目标物品的影像投射到预设位置还不足以为用户提供足够准确的参考，还需要保证该目标物品的影像尺寸等于该目标物品的实际尺寸。而根据投影仪的工作原理，影像尺寸与图片尺寸、移动终端投影透镜的焦距以及移动终端与该预设位置之间的距离密切相关。对于一般的移动终端投影设备，其投影透镜是确定的，那么该透镜的焦距也是确定的，可以通过调节透镜的位置来改变物距和像距，从而使其在预设位置处成清晰的影像。而对于一种确定的目标物品，经过图像处理后的图片的尺 寸大多处在一定范围内，可以在该范围内对图片的大小进行适当的缩放。而调节范围最大的就是移动终端与该预设位置之间的距离了。根据以上这些信息即能够保证在预设位置处，目标物品的影像尺寸等于该目标物品的实际尺寸。
可选的，在本发明的一个实施例中，将经过图像处理后的图片投影到预设位置具体可包括如下步骤：
分别获取所述目标物品在图片中的尺寸和所述目标物品的实际尺寸；
根据所述目标物品在图片中的尺寸和所述目标物品的实际尺寸，确定投影透镜与所述预设位置的理论距离；
当所述投影透镜与所述预设位置的实际距离等于所述投影透镜与所述预设位置的理论距离时，向用户做出提示。
本实施例中，可以通过目标物品中携带的参数信息确定该目标物品的实际尺寸，而目标物品在图片中的尺寸既可以根据原始图片尺寸以及在图像处理中的变换条件获得，也可以现将图片投影到一个成像微镜(如DMD(Digital Micro mirror Device,数字微镜元件))上，然后再投影到预设位置。由于成像微镜上的成像由像素点组成，各像素点之间的间隔是已知的，因此，可以通过统计成像微镜上目标物品的像所占据的像素数来获知像的尺寸，进而获知图片的尺寸。具体而言，获取所述目标物品在图片中的尺寸可包括：将所述图片通过成像微镜后投影；根据所述图片中的目标物品在所述成像微镜中占据的像素数确定所述成像微镜中的目标物品的尺寸；根据所述成像微镜中的目标物品的尺寸确定所述目标物品在图片中的尺寸。
上个实施例中，是根据所述目标物品在图片中的尺寸和所述目标物品的实际尺寸，确定投影透镜与所述预设位置的理论距离的，但本发明不限于此。在本发明的其他实施例中，还可以采用其他方法来确定投影透镜与预设位置之间的理论距离。例如，在确定了成像微镜中的目标物品的尺寸A1后，也可以根据成像微镜与投影透镜之间的距离L1，目标物品的实际尺寸A2(即预设位置处目标物品的影像尺寸)，直接算出预设位置与投影透镜之间的理论距离L2。
其数据关系为:
L2＝L1×A1÷A2  公式(1)
下面通过具体实施例来对本发明提供的移动终端物品显示装置进行详细说明。通过具有投影功能的投影手机可以对需要仔细查看的目标物品进行等比例显示。如图2 所示，投影手机除了包括传统的手机显示模块、手机通讯模块和无线传输模块外(未显示)，还包括投影模块、Apps处理模块、测距模块。其主要工作流程可如图3所示。
该流程分为两部分，一部分需要Apps提供相应的接口配合终端获取数据，另一部分为投影手机进行投影以及测距显示功能，以下从这两个方面来进行说明。
一、Apps接口部分
电商提供的软件提供接口，通过该接口可以提供商品的长宽高、外形图片。该功能主要通过Apps实现，需要Apps针对商品的参数信息提供接口。
Apps处理模块，在接收到API(Application Programming Interface,应用程序编程接口)提供的Message(消息)之前，进行一次刷新功能，确保参数信息的正确性，并对接收到的Apps中的商品参数部分进行预先处理。商品的形状不限，若为不规则商品，提供其最小外接长方体的长宽高即可。
电商提供的软件提供接口，通过该接口可以提供商品的长、宽、高和外形图片。其中，商品的形状不限，若为不规则商品，提供其最小外接长方体的长宽高即可。该功能主要通过Apps实现，需要Apps针对商品的参数信息提供接口。
对于Apps来说，商品参数部分需要特殊处理，提供相应的API接口，这些内容可以提交到投影的智能处理模块。在智能处理模块接收到API提供的Message之前，进行一次刷新功能，确保参数信息的正确性。
在手机的Apps处理模块读取到接口提供的这些信息后，处理模块回馈Get命令，同时使用图像处理芯片对图片进行调整，待调整到最适合人眼观看的图片后，通过API发送至投影模块。
二、投影部分
投影模块接收到Apps处理模块发送的商品的实际大小、商品图片后，在投影模块的成像器件上成像，计算图片上商品的最小外接长方形的长宽，并根据成像器件上每个象素点的大小计算商品图片大小，调节投影模块的镜头焦距及物距，根据几何光学原理计算出最佳投影距离，同时触发测距模块，进行测距的动作。
如果通过调节投影模块的镜头焦距及物距不能达到很好的投影效果，投影模块可根据数字图像处理技术对商品图片进行等比例放大和缩小操作后再进行投影。
测距模块启动后，通过语音或文字，提示用户前进或后退，进行距离测量，当所测距离等于投影模块计算的最佳投影距离时即停止，测距完成后进行投影。
可选的，如图4所示，测距可按照如下方法进行：用户选择参照物，输入参照物的大小，测距模块启动，手机后置摄像头对焦后，利用参照物的实际大小、参照物在手机屏幕上的大小，并结合后置摄像头的焦距及像距，即可计算出参考物的物距，即所需测量的距离。
上述技术既可用于2D投影技术，当3D投影技术完善后，还可以用于3D投影中，只需用3D投影的相关技术代替2D技术即可。
需要说明的是，本实施例中，用户使用Apps查询到相应需要投影的商品，Apps处理模块启动后，手机从APPs模块或者商品的官方网站获取预先设置在APPs内商品的实际长宽高、外形图片；或者，也可以通过商品名称的标题来锁定商品的实际长宽高、外形图片；获取到商品的实际信息后，APPs处理模块会根据商品的长宽高，使用内置的图像处理芯片对商品图片进行处理，达到人眼最适合观看的效果后传递到投影模块进行处理。投影模块在被触发后，首先启动测距模块进行距离测量，然后根据投影模块内预制距离和图片大小的对应参数进行图片的自动调整，之后完成商品投影。测距模块在完成投影距离测量后，提示成功。在完成整个投影功能后，消费者这时可以直观的参考商品的大小和外形等。
通过上述技术方案，在不增加任何硬件的基础上，达到了直观显示商品的效果，避免了用户使用Apps查询到商品后无法直观查看商品的大小等造成不便，提高了用户体验。而且具有较好的可移植性，同样可以移植在各类手机及相关产品上，提高用户的使用方便性。
相应的，本发明还提供一种用于移动终端的物品显示装置，如图5所示，该装置可包括：
获取单元20，设置为获取目标物品的图片和参数信息；
图像处理单元22，设置为根据所述参数信息对所述图片进行图像处理；

可选的，获取单元20可具体设置为：通过所述目标物品所在的应用程序获取所述图片和所述参数信息；或者根据所述目标物品的产品序号从互联网上获取所述图片和所述参数信息。
可选的，图像处理单元22可具体设置为：
