A device for detecting the flatness of a large wall provided by the present invention includes: a housing provided with a flat plane and a light-emitting module; the light-emitting module is arranged inside the housing; The opening through which the emitted light passes; the opening has a shape that can distinguish the direction; the flat plane is glued and connected with the splicing wall. The present invention uses a device that can be installed on the splicing wall and emits light to shine light on the ground in a recognizable direction, so that the position information of the splicing wall can be displayed through the light shining on the ground, so it can be used as a tool for detecting flatness. Basic, the device is installed on the display surface of each unit of the splicing wall, which can detect the flatness of the splicing wall, which is more convenient, faster, accurate and effective than the existing technology, and solves the problem of poor effect or slow efficiency of the traditional detection technology technical issues. The invention also provides a detection method based on the device.
Description
technical field [0001] The invention relates to the technical field of splicing walls, in particular to a device and a detection method for detecting the flatness of a display large wall. Background technique [0002] Now people widely use large display devices, including large splicing screens of LED, LCD and DLP. These splicing large screens are spliced by units one by one, and there are too many units, it is difficult to effectively keep the display surface of each unit on a plane during the installation process. If the display surface of each large screen is not installed on the same plane, the final display will not be beautiful, and the gap between the screens will be uneven, and the best display effect will not be achieved in the end. A large video wall can be called a large display wall. [0003] There are two types of existing methods for detecting and displaying the flatness of large walls: [0004] Option 1: Visual inspection. [0005] Option two: spirit lev...
