Laser Level Grid

Laser Level Grid is an augmented reality (AR) application that makes it easy to hang pictures perfectly. By using your phone in one hand and a pencil in the other, you can eliminate the need to purchase a traditional bubble level and even measuring tools. The grid makes it easy to match the relative spacing between pictures and to center pictures in the space available. The angle finder feature makes it easy to instantly measure angles.

If the lines look a little off (not perfectly level) when you first open it, simply hit the calibrate button and follow the instructions.

Also note, the fish-eye cameras on phones bend the image at the edges and then software straightens everything out, but it isn't usually exact. If you are using the grid feature, use the middle lines for angles and the lines closest to the edges only for checking relative spacing.

激光水平网格是一种增强现实（AR）应用程序，可以很容易地完美地挂起图片。通过单手使用手机和另一只手使用铅笔，您无需购买传统的气泡水平仪甚至测量工具。网格可以轻松匹配图片之间的相对间距以及可用空间中的中心图片。角度查找器功能可以轻松地即时测量角度。

如果第一次打开时线条略显偏离（不完全水平），只需按下校准按钮并按照说明操作即可。

另外请注意，手机上的鱼眼摄像头会在边缘弯曲图像，然后软件将所有内容拉直，但通常不准确。如果使用网格特征，请使用角度的中间线和最靠近边的线，以检查相对间距。
