在本实施例中提供了一种投影方法，图1是根据本发明实施例的投影方法的流程图一，如图1所示，该流程包括如下步骤：
步骤S102，获取用于作为投影背景的目标图像；
步骤S104，提取目标图像的三原色RGB值；
步骤S106，确定与提取的RGB值对应的投影仪参数值；
步骤S108，依据确定的投影仪参数值进行投影。
通过上述步骤，获取用于作为投影背景的目标图像；提取目标图像的三原色RGB值；确定与提取的RGB值对应的投影仪参数值；依据确定的投影仪参数值进行投影，实现了可以根据投影背景的图像颜色来自动对投影仪的参数进行适当的调整，解决了相关技术中存在的投影地点可选择性较少，投影参数需要手动设置的问题，进而达到了提高投影地点的可选择性，实现参数的自动设置，改善用户体验的效果。
在一个可选的实施例中，可以采用如下方法确定与提取的RGB值对应的投影仪参数值，例如，可以将提取的目标图像的RGB值发送至云端服务器，其中，该云端服务器存储有RGB值与投影仪参数值的对应关系；接收云端服务器返回的对提取的RGB值进行匹配后获得的投影仪参数值。在云端服务器中可以预先存储多组RGB值与投影仪参数值之间的对应关系，根据目标图像的RGB值来确定最合适的投影仪参数值。
在一个优选的实施例中，在将提取的目标图像的RGB值发送至云端服务器之前，还可以通过3G/4G无线宽带模块与云端服务器建立3G/4G无线宽带连接，基于建立的 3G/4G无线宽带连接将提取的RGB值发送至云端服务器。这样可以保证，只要在有信号的地方，投影仪便能够连接网络，相对于其他类型的网络连接，3G/4G无线宽带连接受地理区域的限制是较小的，扩大了投影仪的应用范围。
在一个可选的实施例中，还可以采用如下方法确定与提取的RGB值对应的投影仪参数值，获取投影仪本地存储的RGB值与投影仪参数值的对应关系；根据对应关系确定与提取的RGB值对应的投影仪参数值。在本地保存RGB值和投影仪参数值的对应关系可以无需联网便能够直接获取针对目标图像的较佳的投影仪参数。
在一个优选的实施例中，提取目标图像的RGB值包括：获取目标图像预定像素范围内和/或预定比例的颜色特征；根据获取的颜色特征计算目标图像的RGB值。这样可以保证当选择的投影背景上的颜色并非单一的情况下，可以选取投影背景上的预定比例的颜色作为基准颜色，获取该基准颜色的RGB值，进而获取投影仪参数值，保证投影的清晰度。
其中，投影仪参数值可以包括以下至少之一：投影仪的亮度值、对比度、伽马值、色温值、颜色参数、色调参数。
在本实施例中还提供了一种投影方法，图2是根据本发明实施例的投影方法的流程图二，如图2所示，该流程包括如下步骤：

步骤S204，根据接收的RGB值确定投影仪参数值；
步骤S206，将确定的投影仪参数值发送给投影仪进行投影。
通过上述步骤，接收投影仪发送的用于作为投影背景的目标图像的三原色RGB值；根据接收的RGB值确定投影仪参数值；将确定的投影仪参数值发送给投影仪进行投影。实现了可以根据投影背景的图像颜色来自动对投影仪的参数进行适当的调整，解决了相关技术中存在的投影地点可选择性较少，投影参数需要手动设置的问题，进而达到了提高投影地点的可选择性，实现参数的自动设置，改善用户体验的效果。
在一个可选的实施例中，根据接收的RGB值确定投影仪参数值包括：获取云端服务器中存储的RGB值与投影仪参数值的对应关系；利用预定算法对比接收的RGB值与云端服务器中存储的RGB值；根据对比结果选择投影仪参数值。利用预先存储对应表的方式可以减少计算过程，缩短获取投影仪参数的时间。

在相关技术中，由于便携的特性，投影时选择的幕布可以不局限于专门的投影幕布，可以就地取材，选择墙面、办公桌围挡这样的地方作为投影地点。而环境的多样性也造成了一个问题，墙面围挡等非专业的投影屏幕颜色存在多样性，与专门的投影幕布相比，投射的影像在色彩对比和清晰度上会受不同程度的影响，并且，在相关技术中，对投影仪参数的调整需要手动去设置，不能实现参数的自动调整，这在一定程度上也影响了用户体验。因此，针对相关技术中存在的投影地点可选择性较少，投影参数需要手动设置的问题，目前尚未提出有效的解决方案。
针对相关技术中的上述问题，即存在着投影地点可选择性较少，投影参数需要手动设置的问题，为了解决这个问题，结合移动通讯设备的特点，本发明实施例中提供了一种根据当前投影背景颜色自动调整投影颜色的智能移动设备，可以更好的发挥投影仪的便携性和投影效果。
本发明实施例中所提出的包含微型投影仪的智能移动设备，包含以下功能模块：
3G/4G无线宽带模块(同上述建立单元52)，设置为使用移动网络连接云端服务器；
摄像头，设置为获取当前投影背景图像；
数据分析处理模块(同上述提取模块34和第一确定模块36)，设置为分析处理获取图像的颜色信息并发送给云端服务器；
云端服务器(同上述接收模块92、第二确定模块94和发送模块96)，设置为计算背景色和相应的最佳投影仪设置信息(即，投影仪参数值)，和设备进行数据交互；
投影仪控制模块(同上述第一确定模块36和投影模块38)；
微型投影仪。
本发明实施例中记载的自动调整投影颜色的方法包括以下步骤：
第一步，移动宽带设备通过3G/4G无线宽带模块建立3G/4G无线宽带连接；
第二步，摄像头获取投影地点图像；
第三步，数据分析模块进行图像取样分析，将投影背景颜色信息通过无线宽带连接发送到云端服务器；
第四步，云端服务器根据设备传送数据和颜色调整算法计算出最适合当前投影背景颜色的投影图像设置数据，发送回数据处理模块；
第五步，投影仪控制模块根据服务器发回数据修改当前投影仪亮度，对比度，伽马值，色温，颜色，色调等参数，改善投影效果。
与传统的投影仪相比，本实施例的优点是可以根据实际投影地点的颜色自动修正投影仪设置实现投影效果的改进，并且利用无线宽带连接的便捷性将数据对比计算放 到服务器端，算法有修正和更新时直接在服务器端进行，而不需要用户手中设备软件进行升级，并且增加计算和处理速度，缓解设备压力。

3G/4G无线宽带模块1221负责建立3G/4G无线宽带连接，建立连接后智能投影设备可以与云端服务器进行数据交互，可以减少使用网络使用地点的限制。为了节约数据流量，可以对交互过程中需要发送和接收的数据进行压缩，利用压缩后的数据进行数据交互。
摄像头1222设置为获取投影背景图像并保存该投影背景图像。
数据分析处理模块1223负责图像分析处理。这里可以应用成熟的图像颜色特征识别算法，计算目标图像一定像素范围内的颜色特征，并且选取占目标图像预定比例(例如，80％或更高比例)的颜色作为最终图像的基准颜色，保存选取的颜色的RGB值。
云端服务器126存储有一个大数据库，在该数据库中保存着常见的背景颜色与其对应的最佳投影仪图像设置参数(同上述投影仪参数值)，并且使用预定算法对比实际背景颜色和数据库中保存的背景颜色，匹配相应的投影仪图像设置参数，对于新的数据库中未保存的背景颜色，可以利用特定的算法计算出与其相匹配的投影仪图像设置参数，并可以保存新背景颜色和对应于该新背景颜色的投影仪图像设置参数。
投影仪控制模块1224设置为直接控制投影仪的设置和工作，可以自动修改投影仪图像设置参数。
微型投影仪1225将设备中图像和影像投影到当前背景。
图13是根据本法明实施例的智能投影设备工作流程图。如图13所示，该流程包括如下步骤：
步骤S1302，使用摄像头获取当前准备作为投影背景的地点图像，保持获取地点图像时的光线环境与实际投影时的光线环境相同。
步骤S1304，获取投影背景图像后启动数据分析处理模块，得到当前背景图像基准颜色的RGB值。
步骤S1306，使用3G/4G无线宽带模块建立连接至云端图像处理服务器，并将步骤S1304中得到的颜色RGB值发送至服务器。
步骤S1308，云端服务器根据背景颜色匹配对应的投影仪图像设置参数，并将参数通过无线网络发回给设备。
步骤S1310，投影仪控制模块根据服务器发送的参数对投影仪进行设置的修改。
步骤S1312，投影仪使用修正后的数据进行投影。
