具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述本发明实施例的投影设备及其控制方法。
图1是根据本发明一个实施例的投影设备的结构示意图。
如图1所示，该投影设备包括投影模块100、手势检测模块200和控制模块300，其中：
投影模块100设置为向目标载体投影图像。
具体地，在使用投影设备的过程中，投影模块100可根据用户的投影指令，向例如投影屏幕、墙等目标载体投影图像。
需要说明的是，上述投影屏幕和墙仅是目标载体的示例，该实施例的目标载体并不限定于此。
其中，该实施例中的投影设备可以为投影仪、投影手机或便携式投影设备等设备。
手势检测模块200设置为检测用户的手势并生成手势参数。
在本发明的一个实施例中，手势检测模块200检测预设区域内用户的手势输入，其中，该手势检测模块200可采用已有的手势检测组件，例如红外手势检测组件等。
其中，上述手势参数可以为手势移动量，也可以为手势移动后停止时间，为了提高判断效果的准确性，手势参数还可以为手势移动量和手势移动后停止时间。即，手势检测模块200在检测到用户的手势后，可根据用户的手势仅计算手势移动量，也可以根据手势仅确定手势移动后停止时间，还可以根据手势即计算手势移动量，并根据手势确定手势移动后停止时间。
其中，手势移动量为用户的手从第一方向进入预设区域的最大移动距离，手势移动后停止时间为手在进入预设区域且达到最大移动距离后的停止时间，其中，在经过停止时间之后，用户的手以与第一方向相反的第二方向移出预设区域。
需要理解的是，第一方向与第二方向是相对的方向，例如，第一方向为垂直方向上的从上往下，则对应的第二方向为垂直方向上的从下往上，或者，第一方向为垂直方向上的从下往上，则第二方向为垂直方向上的从上往下。
在本发明的一个实施例中，投影模块100包括投影镜头(图中未示出)，且手势检测模块200设置在投影镜头的一侧。
具体地，在投影模块100向目标载体投影图像的过程中，当手势检测模块200检测到用户在投影镜头前做手势时，手势检测模块200获取用户的手势动作信息。
其中，手势检测模块200获取用户的手势动作信息的方式有很多，可以根据实际应用需要进行选择。举例如下：
(1)在手势检测模块200中设置手势感应器，手势检测模块200通过手势感应器获取用户的手势动作信息。
(2)在手势检测模块200中设置红外传感器，手势检测模块200通过红外传感器采集红外强度值变化信息，并根据红外强度值变化信息获得用户的手势动作信息。
需要理解的是，上述举例仅是出于示例性目的，手势检测模块200还可以通过其他方式获取用户的手势操作信息，该实施例对手势检测模块200获取用户的手势动作信息的方式不做限定。
在手势检测模块200获取用户在投影镜头前的预设区域内的手势动作信息后，手势检测模块200对手势动作信息进行分析，以确定用户当前的手势是否以第一方向进入预设区域。
在手势检测模块200确定用户当前的手势是以第一方向进入预设区域后，手势检测模 块200可根据用户的手势计算手势移动量，以及根据用户的手势确定手势移动后停止时间。
具体地，手势检测模块200在确定用户当前的手势是以第一方向进入预设区域后，手势检测模块200可根据用户的手势确定手势沿上下方向移动的范围。
具体而言，在用户通过手势在投影镜头前作从上至下再返回上、或者从下至上再返回下等上下移动时，手势检测模块200可获取到用户的手势，并根据用户的手势计算手势移动量和手势移动后停止时间。
其中，手势沿垂直方向的上下移动的示例图，如图2所示。通过图2中箭头的方向可以确定用户在投影镜头前作的手势的移动方向为从上往下再往上。图2中的第一方向为从上往下，第二方向为从下往上。
例如，手势的移动方向，如图2所示。由于通常在手势上下移动过程中，从上往下移动的幅度与从下往上的幅度会有一定的差异，假定手势从下往上移动的移动距离为a，从下往上移动的移动距离为b，手势检测模块200在计算用户的手势对应的手势移动量的过程中，可将这两个移动距离进行比较，并将其中最大的移动距离作为手势移动量。假设移动距离a小于移动距离b，则将移动距离b作为手势移动量。
控制模块300设置为根据手势参数判断手势是否满足预设条件，并在判断手势满足预设条件时控制投影模块100执行对应地操作。
在本发明的一个实施例中，控制模块300可根据手势参数判断手势是否满足预设条件，并在判断手势满足预设条件时控制投影模块100关闭或者将投影图像切换为默认图像。
需要理解的是，控制模块300除了可以控制投影模块100关闭或者将投影图像切换为默认图像外，还可以执行其他的操作，例如，在投影设备中预先定义了点亮或者关闭投影灯的手势时，在投影灯处于关闭状态使，当手势检测模块200检测到用户输入的手势与预先保存的点亮投影灯的手势相同时，控制模块300可根据用户的手势操作点亮投影灯。或者，在投影灯点亮时，当手势检测模块200检测到用户输入的手势与预先保存的关闭投影灯的手势相同时，控制模块300可根据用户的手势操作关闭投影灯。
其中，需要说明的是，默认图像是投影设备中预先保存的图像，通常投影设备中可以预先保存多张图像，且投影设备通常会预先为用户默认一张图像，用户也可以根据需求重新选择图像，投影设备将根据用户的选择将对应的图像作为默认图像。
具体地，在手势检测模块200生成手势参数后，如果手势参数为手势移动量时，控制模块300可判断手势移动量是否小于或等于预设距离阈值，如果手势移动量小于或等于预设距离阈值，则控制模块300判断手势满足预设条件，控制模块300控制投影模块100执行对应地操作。
另外，在手势检测模块200生成手势参数后，如果手势参数为手势移动后停止时间时， 控制模块300可判断手势移动后停止时间是否大于或等于第一预设时间阈值，如果手势移动后停止时间大于或等于第一预设时间阈值，则控制模块300判断用户的手势满足预设条件，并控制投影模块执行对应地操作。
优选地，在手势参数为手势移动量和手势移动后停止时间时，控制模块300可判断手势移动量是否小于或等于预设距离阈值，以及手势移动后停止时间是否大于或等于第一预设时间阈值，如果手势移动量小于或等于预设距离阈值，且手势移动后停止时间大于或等于第一预设时间阈值，则控制模块300判断手势满足预设条件，并控制投影模块100执行对应地操作，例如，控制模块300判断出用户的手势操作符合关闭投影图像或者将投影图像切换为默认图像的手势条件时，控制模块300控制投影模块100关闭或者将投影图像切换为默认图像。
另外，如果手势移动量小于或等于预设距离阈值，且手势移动后停止时间小于第一预设时间阈值，则控制模块300判断手势不满足预设条件，投影正常运行。
如果手势移动量大于预设距离阈值，且手势移动后停止时间大于或等于第一预设时间阈值，则控制模块300判断手势不满足预设条件，投影正常运行。
如果手势移动量大于预设距离阈值，且手势移动后停止时间小于第一预设时间阈值，则控制模块300判断手势不满足预设条件，投影正常运行。
其中，预设距离阈值是预先设置的手势移动量的距离阈值，例如，预设距离阈值为5cm(厘米)。
其中，第一预设时间阈值是预先设置的手势移动后停止时间的时间阈值，例如，第一预设时间阈值为2s(秒)。
例如，手势的移动方向，如图2所示。假设预设距离阈值为5cm，第一预设时间阈值为2s。在手势检测模块200获取到用户在投影镜头前作垂直方向上的先上后下，再从下往上的移动手势，且用户手势移动后停止时间为3s，假设手势检测模块200获取用户先上后下的移动量为4cm，获取用户从下往上的移动量为4.9cm，此时，手势检测模块200可确定用户当前的手势移动量为4.9cm，且手势移动后停止时间为3s，手势检测模块200将上述所获得的手势移动量和手势移动后停止时间传递给控制模块300，控制模块300通过比较可以确定用户当前的手势移动量小于5cm，此时，控制模块300可进一步确定出用户手势移动后停止时间大于2s，此时，控制模块300可判断出用户当前输入的手势满足预设条件，并控制投影模块100关闭或者将投影图像切换为默认图像。由此，使得通过手势即可关闭投影图像或者将投影图像切换为默认图像，通过手势对投影设备的投影图像进行控制，操作简单方便，提高了用户体验。
根据本发明实施例的投影设备，在投影模块向目标载体投影图像的过程中，通过手势 检测模块检测用户的手势并生成手势参数，以及控制模块根据手势参数判断手势是否满足预设条件，并在判断手势满足预设条件时控制投影模块执行对应地操作，由此，使得投影设备支持用户的手势控制方便了用户通过手势对投影设备进行控制，操作简单、便捷，提高了用户的体验度。
图3是根据本发明另一个实施例的投影设备的结构示意图。
如图3所示，在图1所示实施例的基础上，该投影设备还可以包括计时模块400。
具体地，计时模块400设置为在控制模块300控制投影模块100关闭或者将投影图像切换为默认图像之后进行计时。
其中，上述控制模块300在计时模块400的计时时间大于第二预设时间阈值时控制投影模块开启或者将投影图像切换回正常图像。
其中，第二预设时间阈值是预先设置的控制控制投影模块开启或者将投影图像切换回正常图像的时间阈值，在该实施例中，第二预设时间阈值默认为2分钟，在使用投影设备的过程中，用户也可根据需求自己设置第二预设时间阈值，例如，用户可根据需求将第二预设时间阈值设置为5分钟。
也就是说，控制模块300在监控到计时模块400的计时时间大于第二预设时间阈值时，控制模块300可自动开启投影图像，或者将投影图像切换回正常图像，由此，自动恢复投影图像，减少了用户手动再次开启投影图像的麻烦，提高了用户的体验度。
在本发明的一个实施例中，上述控制模块300还设置为当在计时模块400的计时时间小于第二预设时间阈值，且接收到用户的开启指令时，控制投影模块200开启或者将投影图像切换回正常图像，并将计时模块400清零。也就是说，在控制模块300自动恢复正常投影之前，用户已手动开启投影图像或者将投影图像切换回正常图像。
根据本发明实施例的投影设备，在计时模块的计时时间大于或者等于第二预设时间阈值时，控制模块可自动开启投影图像或者将投影图像切换回正常图像，由此，自动恢复投影图像，减少了用户手动再次开启投影图像的麻烦，提高了用户的体验度。
为了实现上述实施例，本发明还提出一种投影设备控制方法。
图4是本发明一个实施例的投影设备控制方法的流程图。
如图4所示，该投影设备控制方法包括：
S401，在投影设备向目标载体投影图像的过程中，检测用户的手势并生成手势参数。
具体地，在使用投影设备的过程中，可根据用户的投影指令，向例如投影屏幕、墙等目标载体投影图像。
需要说明的是，上述投影屏幕和墙仅是目标载体的示例，该实施例的目标载体并不限定于此。
其中，上述投影设备可以为投影仪、投影手机或便携式投影设备等设备。
其中，手势参数可以包括手势移动量和/或手势移动后停止时间，即在后续判断中，可通过手势移动量对手势是否满足预设条件进行判断，或者，通过手势移动后停止时间对手势是否满足预设条件进行判断，优选地，可通过手势移动量和手势移动后停止时间这两个参数对手势是否满足预设条件进行判断。
其中，手势移动量为用户的手从第一方向进入预设区域的最大移动距离，手势移动后停止时间为手在进入预设区域且达到最大移动距离后的停止时间，其中，在经过停止时间之后，用户的手以与第一方向相反的第二方向移出预设区域。
需要理解的是，第一方向与第二方向是相对的方向，例如，第一方向为垂直方向上的从上往下，则对应的第二方向为垂直方向上的从下往上，或者，第一方向为垂直方向上的从下往上，则第二方向为垂直方向上的从上往下。
具体而言，在获取用户在投影设备的投影镜头前预设区域内的手势动作信息后，对手势动作信息进行分析，以确定用户当前的手势是否以第一方向进入预设区域。
在确定用户当前的手势是以第一方向进入预设区域后，手势检测模块200可根据用户的手势计算手势移动量，以及根据用户的手势确定手势移动后停止时间。
具体地，在确定用户当前的手势是以第一方向进入预设区域后，可根据用户的手势确定手势沿上下方向移动的范围。
具体而言，在用户通过手势在投影镜头前作从上至下再返回上、或者从下至上再返回下等上下移动时，可获取到用户的手势，并根据用户的手势计算手势移动量和手势移动后停止时间。
其中，手势沿垂直方向的上下移动的示例图，如图2所示。通过图2中箭头的方向可以确定用户在投影镜头前作的手势的移动方向为从上往下再往上。图2中的第一方向为从上往下，第二方向为从下往上。
例如，手势的移动方向，如图2所示。由于通常在手势上下移动过程中，从上往下移动的幅度与从下往上的幅度会有一定的差异，假定手势从下往上移动的移动距离为a，从下往上移动的移动距离为b，手势检测模块200在计算用户的手势对应的手势移动量的过程中，可将这两个移动距离进行比较，并将其中最大的移动距离作为手势移动量。假设移动距离a小于移动距离b，则将移动距离b作为手势移动量。
S402，根据手势参数判断手势是否满足预设条件。
具体地，在根据手势生成手势参数后，如果手势参数为手势移动量时，可判断手势移 动量是否小于或等于预设距离阈值，如果手势移动量小于或等于预设距离阈值，则判断手势满足预设条件。
另外，如果手势参数为手势移动后停止时间时，可判断手势移动后停止时间是否大于或等于第一预设时间阈值，如果手势移动后停止时间大于或等于第一预设时间阈值，则判断用户的手势满足预设条件。
在根据手势生成手势参数后，如果手势参数为手势移动量和手势移动后停止时间，可先判断手势移动量是否小于或等于预设距离阈值，如果手势移动量小于或等于预设距离阈值，则进一步判断手势移动后停止时间是否大于或等于第一预设时间阈值，如果手势移动量小于或等于预设距离阈值，且手势移动后停止时间大于或等于第一预设时间阈值，则判断手势满足预设条件，即判断出用户的手势操作符合关闭投影图像或者将投影图像切换为默认图像的条件。
另外，如果手势移动量小于或等于预设距离阈值，且手势移动后停止时间小于第一预设时间阈值，则判断手势不满足预设条件，投影正常运行。
如果手势移动量大于预设距离阈值，且手势移动后停止时间大于或等于第一预设时间阈值，则判断手势不满足预设条件，投影正常运行。
如果手势移动量大于预设距离阈值，且手势移动后停止时间小于第一预设时间阈值，则判断手势不满足预设条件，投影正常运行。
其中，预设距离阈值是预先设置的手势移动量的距离阈值，例如，预设距离阈值为5cm(厘米)。
其中，第一预设时间阈值是预先设置的手势移动后停止时间的时间阈值，例如，第一预设时间阈值为2s(秒)。
S403，如果手势满足预设条件，则控制投影设备执行对应地操作。
在本发明的一个实施例中，在投影设备投影图像的过程中，在根据用户在投影镜头前所做的手势生成手势参数后，可根据手势参数判断手势是否满足预设条件，并在判断手势满足预设条件时，控制投影设备关闭投影图像或者将投影图像切换为默认图像。
需要理解的是，除了可以控制投影设备关闭投影图像或者将投影图像切换为默认图像外，还可以控制投影设备执行其他的操作，例如，在投影设备中预先定义了点亮或者关闭投影灯的手势时，在投影灯关闭时，在检测到用户输入的手势与预先保存的点亮投影灯的手势相同时，可控制投影设备将投影灯点亮。或者，在投影灯点亮时，当检测到用户输入的手势与预先保存的关闭投影灯的手势相同时，可根据用户的手势操作关闭投影灯。其中，需要说明的是，默认图像是投影设备中预先保存的图像，通常投影设备中可以预先保存多张图像，且投影设备通常会预先为用户默认一张图像，用户也可以根据需求重新选择图像， 投影设备将根据用户的选择将对应的图像作为默认图像。
例如，手势的移动方向，如图2所示。假设预设距离阈值为5cm，第一预设时间阈值为2s。在获取到用户在投影镜头前作垂直方向上的先上后下，再从下往上的移动手势，且用户手势移动后停止时间为3s，假设获取用户先上后下的移动量为4cm，获取用户从下往上的移动量为4.9cm，此时，可确定用户当前的手势移动量为4.9cm，且手势移动后停止时间为3s，通过比较可以确定用户当前的手势移动量小于5cm，并进一步确定出用户手势移动后停止时间大于2s，此时，可判断出用户当前输入的手势满足预设条件，可关闭投影图像或者将投影图像切换为默认图像。由此，使得通过手势即可关闭投影图像或者将投影图像切换为默认图像，通过手势对投影设备的投影图像进行控制，操作简单方便，提高了用户体验。
根据本发明实施例的投影设备控制方法，在向目标载体投影图像的过程中，检测用户的手势并生成手势参数，以及根据手势参数判断手势是否满足预设条件，并在判断手势满足预设条件时控制投影设备执行对应地操作，由此，方便了用户通过手势对投影设备进行控制，操作简单、便捷，提高了用户的体验度。
图5是本发明另一个实施例的投影设备控制方法的流程图。
如图5所示，该投影设备控制方法包括：
S501，在投影设备向目标载体投影图像的过程中，检测用户的手势并生成手势参数。
具体地，在使用投影设备的过程中，可根据用户的投影指令，向例如投影屏幕、墙等目标载体投影图像。
需要说明的是，上述投影屏幕和墙仅是目标载体的示例，该实施例的目标载体并不限定于此。
其中，投影设备可以为投影仪、投影手机或便携式投影设备等设备。
其中，手势参数可以包括手势移动量和/或手势移动后停止时间，即在后续判断中，可通过手势移动量对手势是否满足预设条件进行判断，或者，通过手势移动后停止时间对手势是否满足预设条件进行判断，优选地，可通过手势移动量和手势移动后停止时间这两个参数对手势是否满足预设条件进行判断。
其中，手势移动量为用户的手从第一方向进入预设区域的最大移动距离，手势移动后停止时间为手在进入预设区域且达到最大移动距离后的停止时间，其中，在经过停止时间之后，用户的手以与第一方向相反的第二方向移出预设区域。
需要理解的是，第一方向与第二方向是相对的方向，例如，第一方向为垂直方向上的从上往下，则对应的第二方向为垂直方向上的从下往上，或者，第一方向为垂直方向上的 从下往上，则第二方向为垂直方向上的从上往下。
具体而言，在获取用户在投影设备的投影镜头前预设区域内的手势动作信息后，对手势动作信息进行分析，以确定用户当前的手势是否以第一方向进入预设区域。
在确定用户当前的手势是以第一方向进入预设区域后，手势检测模块200可根据用户的手势计算手势移动量，以及根据用户的手势确定手势移动后停止时间。
具体地，在确定用户当前的手势是以第一方向进入预设区域后，可根据用户的手势确定手势沿上下方向移动的范围。
具体而言，在用户通过手势在投影镜头前作从上至下再返回上、或者从下至上再返回下等上下移动时，可获取到用户的手势，并根据用户的手势计算手势移动量和手势移动后停止时间。
其中，手势沿垂直方向的上下移动的示例图，如图2所示。通过图2中箭头的方向可以确定用户在投影镜头前作的手势的移动方向为从上往下再往上。图2中的第一方向为从上往下，第二方向为从下往上。
例如，手势的移动方向，如图2所示。由于通常在手势上下移动过程中，从上往下移动的幅度与从下往上的幅度会有一定的差异，假定手势从下往上移动的移动距离为a，从下往上移动的移动距离为b，手势检测模块200在计算用户的手势对应的手势移动量的过程中，可将这两个移动距离进行比较，并将其中最大的移动距离作为手势移动量。假设移动距离a小于移动距离b，则将移动距离b作为手势移动量。
S502，根据手势参数判断手势是否满足预设条件。
具体地，在根据手势生成手势参数后，如果手势参数为手势移动量时，可判断手势移动量是否小于或等于预设距离阈值，如果手势移动量小于或等于预设距离阈值，则判断手势满足预设条件。
另外，如果手势参数为手势移动后停止时间时，可判断手势移动后停止时间是否大于或等于第一预设时间阈值，如果手势移动后停止时间大于或等于第一预设时间阈值，则判断用户的手势满足预设条件。
在根据手势生成手势参数后，如果手势参数为手势移动量和手势移动后停止时间时，可先判断手势移动量是否小于或等于预设距离阈值，如果手势移动量小于或等于预设距离阈值，则进一步判断手势移动后停止时间是否大于或等于第一预设时间阈值，如果手势移动量小于或等于预设距离阈值，且手势移动后停止时间大于或等于第一预设时间阈值，则判断手势满足预设条件，即判断出用户的手势操作符合关闭投影图像或者将投影图像切换为默认图像的条件。
另外，如果手势移动量小于或等于预设距离阈值，且手势移动后停止时间小于第一预 设时间阈值，则判断手势不满足预设条件，投影正常运行。
如果手势移动量大于预设距离阈值，且手势移动后停止时间大于或等于第一预设时间阈值，则判断手势不满足预设条件，投影正常运行。
如果手势移动量大于预设距离阈值，且手势移动后停止时间小于第一预设时间阈值，则判断手势不满足预设条件，投影正常运行。
其中，预设距离阈值是预先设置的手势移动量的阈值，例如，预设距离阈值为5cm。
其中，第一预设时间阈值是预先设置的手势移动后停止时间的时间阈值，例如，第一预设时间阈值为2s。
S503，如果手势满足预设条件，则控制投影设备关闭投影图像或者将投影图像切换为默认图像。
其中，需要说明的是，默认图像是投影设备中预先保存的图像，通常投影设备中可以预先保存多张图像，且投影设备通常会预先为用户默认一张图像，用户也可以根据需求重新选择自己的图像，投影设备将根据用户的选择将对应的图像作为默认图像。
例如，手势的移动方向，如图2所示。假设预设距离阈值为5cm，第一预设时间阈值为2s。在获取到用户在投影镜头前作垂直方向上的先上后下，再从下往上的移动手势，且用户手势移动后停止时间为3s，假设获取用户先上后下的移动量为4cm，获取用户从下往上的移动量为4.9cm，此时，可确定用户当前的手势移动量为4.9cm，且手势移动后停止时间为3s，通过比较可以确定用户当前的手势移动量小于5cm，并进一步确定出用户手势移动后停止时间大于2s，此时，可判断出用户当前输入的手势满足预设条件，可关闭投影图像或者将投影图像切换为默认图像。由此，使得通过手势即可关闭投影图像或者将投影图像切换为默认图像，通过手势对投影设备的投影图像进行控制，操作简单方便，提高了用户体验。
S504，在控制投影设备关闭投影图像或者将投影图像切换为默认图像之后进行计时，并在计时时间大于第二预设时间阈值时，控制投影设备开启投影图像或者将投影图像切换回正常图像。
另外，在本发明的一个实施例中，如图6所示，该投影设备控制方法还可以包括S504。
S505，在计时时间小于第二预设时间阈值，接收到用户的开启指令时，控制投影设备开启投影图像或者将投影图像切换回正常图像，并将计时模块清零。
其中，需要说明的是，步骤S504和步骤S505的执行顺序不分先后。
根据本发明实施例的投影设备控制方法，在向目标载体投影图像的过程中，检测用户的手势并生成手势参数，以及根据手势参数判断手势是否满足预设条件，并在判断手势满足预设条件时关闭投影图像或者将投影图像切换为默认图像，由此，使得用户通过手势即 可关闭投影图像或者将投影图像切换为默认图像，方便了用户通过手势对投影设备进行控制，操作简单、便捷，提高了用户的体验度。
