Embodiment Construction

[0048] 1. The measurement of the distance is generally carried out according to the following steps:

[0049] (1) Turn on the mobile phone and select the measurement mode. The optional modes are:

[0050] · Measure horizontal distance

[0051] · Measure vertical height

[0052] · Measure the distance between two points

[0053] · Measure the height between two points

[0054] (2) The height h of the preset measurement point from the ground.

[0055] (3) Turn on the camera and take pictures of the measurement points.

[0056] (4) Obtain the value of the sensor in the mobile phone.

[0057] (5) Calculate the horizontal or vertical measurement distance.

[0058] (6) Perform error correction.

[0059] Among them, (4), (5), and (6) are automatically carried out by the program.

[0060] 2. Measurement of horizontal distance.

[0061] For example, to measure the distance between a person and a door, the steps are as follows:

[0062] (1) Select the measurement mode as horiz...

Abstract

The invention discloses an intelligent cell phone ranging method based on an android platform. The ranging method comprises the following steps: photographing a measurement point by a camera of a cell phone, calculating the horizontal distance between a measurement object and the measurement point, the distance between any two points in the same plane, the distance between the object and the ground and the distance between any two points in the vertical surface by a program according to the roll value and the pitch value of a directional sensor of the cell phone; correcting possible errors of the measurement value during calculation, wherein the measurement error is within 1% generally. The android platform provided by the invention can be installed in the cell phone as an application, and the ranging method is simple to operate, convenient to use, practical in function, accurate in ranging, and wide in application area.

Description

technical field [0001] The invention relates to a method for horizontal distance measurement and vertical distance measurement using a mobile phone on an Android platform. Background technique [0002] Distance measurement is a common requirement in work and life, ranging from height measurement in daily life, design measurement in home layout, to marking measurement of competition venues, construction measurement on construction sites, etc. The most commonly used distance measuring method is to use a ruler as a measuring tool to measure. When the measured distance is long, far away, or difficult to approach, it will bring difficulties to the measurement. In engineering measurement, optical or acoustic principles such as infrared rays and sonar are commonly used for measurement. At this time, professional measuring tools are required. Various sensors in smartphones make it possible to meet this demand. [0003] Based on mobile phone ranging, the disclosed methods include: ...
