可选地，本发明实施例中除了采集激光笔的轨迹外，还要采集激光颜色。这样的话需要事先设置图像形状和激光颜色与控制操作之间的对应关系，只有在激光笔颜色和激光笔轨迹的形状与事先设置的图像形状和激光颜色同时匹配时，才执行所匹配的控制操作。Optionally, in addition to acquiring the trajectory of the laser pointer, the laser color is also collected in the embodiment of the present invention. In this case, the correspondence between the image shape and the laser color and the control operation needs to be set in advance, and the matched control operation is performed only when the shape of the laser pointer color and the laser pointer track are matched with the previously set image shape and laser color. .
可选地，该对应关系可以包括：一项控制操作与一项图像数据和一种激光笔的显示色彩相对应，一项控制操作与多项图像数据和多种激光笔的显示色彩相对应，一项控制操作与多项图像数据和一种激光笔的显示色彩相对应，一项控制操作与一项图像数据和多种激光笔的显示色彩相对应；多项控制操作与一项图像数据和一种激光笔的显示色彩相对应，也可以是多项控制操作与多项图像数据和一种激光笔的显示色彩相对应，多项控制操作与一项图像数据和多种激光笔的显示色彩相对应，多项控制操作与多项图像数据和多种激光笔的显示色彩相对应等。Optionally, the correspondence may include: a control operation corresponding to an image data and a display color of a laser pen, and a control operation corresponding to the display color of the plurality of image data and the plurality of laser pens, A control operation corresponds to a plurality of image data and a display color of a laser pen, and a control operation corresponds to an image data and display colors of a plurality of laser pens; a plurality of control operations and an image data and A display color corresponding to a laser pen, or a plurality of control operations corresponding to a plurality of image data and a display color of a laser pen, a plurality of control operations and an image data and display colors of the plurality of laser pens Correspondingly, a plurality of control operations correspond to a plurality of image data and display colors of a plurality of laser pens.
具体地，投影仪可以通过文字交互方式提示用户初始化工作。投影仪在开始检测投影面光源时，可以根据激光笔的显示色彩和用户使用习惯，配置交互策略，同时预置可绘制区域(即设定区域)，避免与显示内容区域重叠。Specifically, the projector can prompt the user to initialize the work by text interaction. When the projector starts to detect the projection surface light source, the interactive strategy can be configured according to the display color of the laser pointer and the user's usage habits, and the drawable area (ie, the set area) is preset to avoid overlapping with the display content area.
例如，投影仪可以通过附摄像头采集激光笔光源反射频率，让其受控指定“控制器”。即通过摄像头拍摄的图像在设定区域进行数字图像处理(可减少计算量，提高精度及运算速度)，逐行检测激光投影在屏幕上颜色，通过RGB颜色与相邻“白”区域造成的像素值突变，锁定激光笔投影颜色，化为默认激光控制颜色。For example, the projector can capture the reflected frequency of the laser pen light source with a camera and let it control the designated "controller". That is, the image captured by the camera performs digital image processing in the set area (the amount of calculation can be reduced, the accuracy and the calculation speed can be reduced), and the color of the laser projection on the screen is detected line by line, and the pixels caused by the RGB color and the adjacent "white" area are detected. The value is abrupt, locking the laser pen projection color and turning it into the default laser control color.
投影仪还可以通过附摄像头采集激光笔光源运动轨迹，通过数字图像处理技术综合判断，设定响应类型。即PPT讲演时，画面是固定的，摄像头通过连续拍摄，当在指定区域有RGB颜色值突变时，会就近把前后数十帧图像进行比对重合，如此可以动态绘出讲演者通过激光笔所绘制的轨迹，进行对应的控制操作，如换页显示操作(下一页、上一页)、返回主菜单、关机等；The projector can also collect the trajectory of the laser pen light source through the attached camera, and comprehensively judge the digital image processing technology to set the response type. That is, when the PPT is being lectured, the picture is fixed. When the camera shoots continuously, when there is a sudden change in the RGB color value in the specified area, the images of the dozens of frames before and after will be compared, so that the speaker can be dynamically drawn by the laser pointer. Draw the trace, perform corresponding control operations, such as page change display operation (next page, previous page), return to main menu, shutdown, etc.
假设预置正方形对应的控制操作为返回主菜单操作。Assume that the control operation corresponding to the preset square is to return to the main menu operation.
三角形对应的控制操作为关机操作。The control operation corresponding to the triangle is the shutdown operation.
回勾对应的控制操作为上一页(近似back键)操作。： The control operation corresponding to the checkback is the previous page (approximate back button) operation. :
直线对应的控制操作为下一页(近似直线，左至右)操作。The control operation corresponding to the line is the next page (approximately straight line, left to right) operation.
另外，投影仪还可以提示用户可操作区域，并复现用户所使用激光笔显示轨迹对应投影仪动作,如操作基本ppt功能,投影仪简单的关机、调整亮度等。In addition, the projector can also prompt the user to operate the area, and reproduce the action of the laser pointer displayed by the user corresponding to the projector, such as operating the basic ppt function, the projector simply shuts down, adjusts the brightness, and the like.
可选地，投影仪将识别处理结果与预置的各项控制操作对应的图像数据匹配后，若匹配成功，可以向用户显示所匹配成功的控制操作，当用户确认执行该控制操作时，再按照匹配成功的控制操作进行处理。这样可以避免误操作，从而提高控制操作的可靠性。Optionally, after the projector matches the recognition processing result with the image data corresponding to the preset control operations, if the matching is successful, the matching control operation may be displayed to the user, and when the user confirms that the control operation is performed, Processed according to the matching control operation. This avoids misoperations and improves the reliability of control operations.
