Embodiment Construction
[0107] The projection device in the embodiment of the present invention transmits position information corresponding to the area to each area within the projection range; the projection device receives feedback from the identification device based on the identified position information of the identification device relative to the projection range Position identification, wherein the identification device is located around the projection screen; the projection device adjusts the projection range according to the position identification fed back by the identification device, so that the adjusted projection range overlaps with the projection screen. Since the embodiment of the present invention can automatically obtain adjustment parameters for overlapping the image projected by the projection device with the projection screen, the projection device can be automatically adjusted, and the adjustment speed and adjustment accuracy are improved.
[0108] like figure 1 As shown, the s...

The present invention relates to the field of electronic equipment, in particular to a method and device for adjusting a projected image, so as to solve the problems that the existing method for adjusting a projected image needs to manually adjust the image, which takes a long time and the adjustment accuracy is not high. The method provided by the embodiment of the present invention includes: the projection device transmits position information corresponding to the area to each area within the projection range; The position identification determined by the position information, wherein the identification device is located around the projection screen; the projection device adjusts the projection range according to the position identification fed back by the identification device, so that the adjusted projection range coincides with the projection screen . Therefore, the method provided by the embodiment of the present invention can automatically complete the projection image adjustment, which improves the degree of automation and adjustment accuracy.
Description
technical field [0001] The invention relates to the field of electronic equipment, in particular to a method and equipment for adjusting projected images. Background technique [0002] A projection device is a device that can project images or videos, and can be used to display larger-sized images. Projection equipment is often used in conjunction with projection screens to increase the resolution of displayed images, enrich display colors, and obtain better display effects. In actual use, the projection device needs to be adjusted so that the projected image coincides with the projection screen. [0003] Early projection equipment was less difficult to adjust. Because the old-fashioned projection equipment requires a large projection distance, it is generally used in places such as conference rooms, and the projection equipment is often fixed on a fixed position such as a wall. The position of the projection device is fixed, which is convenient for the operator to adjust...
