本发明的最佳实施方式BEST MODE FOR CARRYING OUT THE INVENTION
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
本发明的一个实施例提供了一种投影设备，如图1所示，该投影设备1包括光束发生器10，该光束发生器10用于发射第一光束a1、第二光束a2和第三光束a3，当投影设备1和预设大小的矩形屏幕2之间的位置为预设相对位置时，第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影线与矩形屏幕2的任意三边重合。One embodiment of the present invention provides a projection apparatus. As shown in FIG. 1, the projection apparatus 1 includes a beam generator 10 for emitting a first beam a1, a second beam a2, and a third beam. A3, when the position between the projection device 1 and the rectangular screen 2 of the preset size is a preset relative position, the projection lines of the first beam a1, the second beam a2, and the third beam a3 on the rectangular screen 2 and the rectangular screen Any three sides of 2 coincide.
本实施例中仅以设置于垂直于水平面的墙上的矩形屏幕2为例进行说明，但是，在其他实施例中，矩形屏幕2也可以设置在天花板上，本发明并不对矩形屏幕2的放置方式进行限定。In this embodiment, only the rectangular screen 2 disposed on the wall perpendicular to the horizontal plane is taken as an example. However, in other embodiments, the rectangular screen 2 may also be disposed on the ceiling, and the present invention does not place the rectangular screen 2. The method is limited.
如图1所示，第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影线与矩形屏幕2的任意三边重合可以为第一光束a1与矩形屏幕2的第一边b1重合、第二光束a2与矩形屏幕的第二边b2重合、第三光束a3与矩形屏幕的第三边b3重合，当然，在其他实施例中，第一光束a1也可以与矩形屏幕2的第四边b4重合，本发明并不仅限于此。As shown in FIG. 1, the projection lines of the first beam a1, the second beam a2, and the third beam a3 on the rectangular screen 2 coincide with any three sides of the rectangular screen 2, which may be the first of the first beam a1 and the rectangular screen 2. The side beam b1 coincides, the second light beam a2 coincides with the second side b2 of the rectangular screen, and the third light beam a3 coincides with the third side b3 of the rectangular screen. Of course, in other embodiments, the first light beam a1 may also be combined with the rectangular screen 2 The fourth side b4 overlaps, and the present invention is not limited thereto.
本实施例中，在投影设备1初始安装时，专业的安装人员会将投影设备1与矩形屏幕2之间的相对位置校调到最佳位置，该最佳位置即所述预设相对位置，然后固定光束发生器10的发射角度和位置关系，使得第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影线与矩形屏幕2的任意三边重合。In this embodiment, when the projection device 1 is initially installed, a professional installer adjusts the relative position between the projection device 1 and the rectangular screen 2 to an optimal position, that is, the preset relative position. The emission angle and positional relationship of the beam generator 10 are then fixed such that the projection lines of the first beam a1, the second beam a2, and the third beam a3 on the rectangular screen 2 coincide with any three sides of the rectangular screen 2.
其中，在初始安装阶段，固定光束发生器10的发射角度和位置关系可以调节，但是，其角度和位置关系固定下来后，就不会随投影设备1的位置改变而改变了，即不随投影设备1的水平状态和高度状态的改变而改变。也就是说，若投影设备1的水平状态和高度状态改变，则光束发生器10发射的光束在投影屏幕上的投影位置会改变，但是该光束相对于投影设备1的角度关系以及三束光束之间的相对位置关系不会随投影设备1的水平状态和高度状态的改变而改变。Wherein, in the initial installation stage, the transmission angle and the positional relationship of the fixed beam generator 10 can be adjusted, but after the angle and the positional relationship are fixed, the position of the projection device 1 does not change, that is, does not follow the projection device. The horizontal state and the height state of 1 change. That is, if the horizontal state and the height state of the projection apparatus 1 are changed, the projection position of the light beam emitted from the beam generator 10 on the projection screen changes, but the angular relationship of the light beam with respect to the projection apparatus 1 and the three beams of light The relative positional relationship between the two does not change with the change of the horizontal state and the height state of the projection apparatus 1.
例如，以投影设备1的形状近似为长方体为例，将投影设备1的上表面作为基准面，假设第一光束a1与基准面的夹角为45度，第二光束a2和第三光束a3都垂直于基准面，第二光束a2与第三光束a3的夹角为60度，则无论投影设备1的位置如何变化，第一光束a1与基准面的夹角一直保持45度，第二光束a2和第三光束a3也一直都垂直于基准面，第二光束a2与第三光束a3的夹角也一直保持在60度。For example, taking the shape of the projection device 1 as a rectangular parallelepiped as an example, the upper surface of the projection device 1 is used as a reference surface, assuming that the angle between the first light beam a1 and the reference surface is 45 degrees, and the second light beam a2 and the third light beam a3 are both The angle between the second beam a2 and the third beam a3 is 60 degrees perpendicular to the reference plane, and the angle between the first beam a1 and the reference plane is maintained at 45 degrees regardless of the position of the projection device 1, and the second beam a2 The third beam a3 is also always perpendicular to the reference plane, and the angle between the second beam a2 and the third beam a3 is also maintained at 60 degrees.
可选的，投影设备1的最佳位置可以为投影设备1的出光口在矩形屏幕2上的投影位置位于矩形屏幕2垂直于水平面的对称轴上。在其他实施例中，投影设备1的最佳位置可以为投影设备1与矩形屏幕2的中心点相隔预设距离。当然，本发明并不对最佳位置具体限定，只需保证最佳位置时投影设备1投射的图像在矩形屏幕2上形成的矩形投影区域与矩形屏幕2重合，且矩形屏幕2上呈现的图像清晰、准确即可。Alternatively, the optimal position of the projection device 1 may be that the projection position of the light exit port of the projection device 1 on the rectangular screen 2 is located on the axis of symmetry of the rectangular screen 2 perpendicular to the horizontal plane. In other embodiments, the optimal position of the projection device 1 may be a predetermined distance between the projection device 1 and the center point of the rectangular screen 2. Of course, the present invention does not specifically limit the optimal position, and only the rectangular projection area formed on the rectangular screen 2 by the image projected by the projection apparatus 1 coincides with the rectangular screen 2 when the optimal position is ensured, and the image presented on the rectangular screen 2 is clear. And accurate.
也就是说，本实施例中的矩形屏幕2与投影设备1具有预设相对位置指的是：投影设备1在预设的初始状态下投射的图像在矩形屏幕2上形成的矩形投影区域与矩形屏幕2重合。That is to say, the rectangular screen 2 and the projection device 1 in the present embodiment have a preset relative position, which refers to a rectangular projection area and a rectangle formed on the rectangular screen 2 by the image projected by the projection device 1 in a preset initial state. Screen 2 coincides.
对投影设备1进行初始校调后，在后续的使用过程中，如果投影设备1到矩形屏幕2之间的距离发生变化，或者，投影设备1与矩形屏幕2的四个顶点的距离发生变化即投影方向发生偏转，那么，第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影位置也会发生变化，此时，用户只需在校调投影设备1时判断第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影线是否与矩形屏幕2的上述三边重合，即可判断投影设备1与矩形屏幕2之间的相对位置是否为预设相对位置即最佳位置，从而简化了投影设备的校调过程。After the initial calibration of the projection device 1, during the subsequent use, if the distance between the projection device 1 and the rectangular screen 2 changes, or the distance between the projection device 1 and the four vertices of the rectangular screen 2 changes, When the projection direction is deflected, the projection positions of the first beam a1, the second beam a2, and the third beam a3 on the rectangular screen 2 also change. At this time, the user only needs to judge the first when the projection device 1 is adjusted. Whether the projection line of the light beam a1, the second light beam a2, and the third light beam a3 on the rectangular screen 2 coincides with the above three sides of the rectangular screen 2, it can be determined whether the relative position between the projection device 1 and the rectangular screen 2 is a preset. The relative position is the optimal position, which simplifies the calibration process of the projection device.
本实施例中，光束发生器10可以包括发射第一光束a1的第一激光模组、发射第二光束a2的第二激光模组和发射第三光束a3的第三激光模组。其中，每个激光模组均包括激光器和位于对应激光器出射光路上的扩束器。由于扩束器能够将激光束扩展成在具有预设角度的平面内传播的光束，因此，第一激光模组发射的第一光束a1、第二激光模组发射的第二光束a2以及第三激光模组发射的第三光束a3能够在矩形屏幕2上形成一定长度的投影线。In this embodiment, the beam generator 10 may include a first laser module that emits the first light beam a1, a second laser module that emits the second light beam a2, and a third laser module that emits the third light beam a3. Each of the laser modules includes a laser and a beam expander located on the exiting path of the corresponding laser. Since the beam expander can expand the laser beam into a light beam propagating in a plane having a preset angle, the first beam a1 emitted by the first laser module, the second beam a2 emitted by the second laser module, and the third The third light beam a3 emitted by the laser module is capable of forming a projection line of a certain length on the rectangular screen 2.
本实施例中，投影设备1包括水平调节装置、水平仪和高度调节装置。水平调节装置用于调节投影设备1的水平状态以及第一光束a1、第二光束a2和第三光束a3的投影位置。水平仪用于判断投影设备1是否处于水平状态。高度调节装置用于调节投影设备1的高度以及第一光束a1、第二光束a2和第三光束a3的投影位置。In the present embodiment, the projection apparatus 1 includes a level adjusting device, a level, and a height adjusting device. The level adjusting means is for adjusting the horizontal state of the projection apparatus 1 and the projection positions of the first light beam a1, the second light beam a2, and the third light beam a3. The level is used to judge whether the projection device 1 is in a horizontal state. The height adjustment means is for adjusting the height of the projection apparatus 1 and the projection positions of the first light beam a1, the second light beam a2, and the third light beam a3.
当投影设备1与矩形屏幕2之间的相对位置发生改变时，该相对位置包括投影设备1到矩形屏幕2之间的距离以及投影设备1到矩形屏幕2的四个顶点之间的距离，用户可通过水平调节装置和高度调节装置等调节投影设备1的位置。When the relative position between the projection device 1 and the rectangular screen 2 is changed, the relative position includes the distance between the projection device 1 to the rectangular screen 2 and the distance between the projection device 1 to the four vertices of the rectangular screen 2, the user The position of the projection device 1 can be adjusted by a level adjusting device, a height adjusting device, or the like.
在通过水平调节装置调节投影设备1的过程中，第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影线的位置也会发生变化，在通过高度调节装置调节投影设备1的过程中，第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影线的位置也会发生变化，因此，只需判断第一光束a1、第二光束a2和第三光束a3在矩形屏幕2上的投影线是否与矩形屏幕2的上述三边重合，即可判断投影设备1的位置是否为最佳位置。In the process of adjusting the projection apparatus 1 by the level adjusting means, the positions of the projection lines of the first light beam a1, the second light beam a2 and the third light beam a3 on the rectangular screen 2 also change, and the projection apparatus is adjusted by the height adjusting means. In the process of 1, the positions of the projection lines of the first beam a1, the second beam a2, and the third beam a3 on the rectangular screen 2 also change, and therefore, it is only necessary to judge the first beam a1, the second beam a2, and the Whether or not the projection line of the three-beam a3 on the rectangular screen 2 coincides with the above-mentioned three sides of the rectangular screen 2 can determine whether the position of the projection apparatus 1 is the optimum position.

The projection line on the rectangular screen coincides with any three sides of the rectangular screen, so that the relative position between the projection device and the rectangular screen is a preset relative position, that is, the position of the professional installer at the initial installation, thereby solving the problem due to the projection device and The problem that the user cannot view the projected image normally due to the change in the relative position of the screen.
