尺子-阑珊尺子测量工具&手机直尺 1.0.1

The Mobile Ruler Measurement Tool is an application that utilizes the camera and sensors of a smartphone to measure lengths. By using this tool, users can aim their smartphone at the object to be measured, take a photo, and then measure the dimensions such as length, width, and height based on markers or guidelines in the photo.

These applications can measure by referencing objects or by calculating the number of pixels of the object in the photo and converting it to actual dimensions for measurement. Additionally, these apps typically include features like marking, screenshotting, saving, and sharing to facilitate users in recording and sharing measurement results.

Although the Mobile Ruler Measurement Tool is very convenient and easy to use, its measuring accuracy is limited by the precision of the smartphone's camera and sensors. Consequently, its results may be affected by some margin of error. Furthermore, since this tool does not have physical ruler markings, users also need to have a certain understanding and experience regarding its usage methods and precision.
