Object size measurement method and system and intelligent terminal

Abstract

The invention provides an object size measurement method and system and an intelligent terminal. The object size measurement method comprises the following steps that the measurement mode of a camera is initialized; the camera photographs an object to be measured and forms an image in the measurement area on a screen; meanwhile, a reference object arranged in the same measurement plane with the object to be measured is also photographed, and an image is formed in the reference area on the screen; the first pixel value of the object to the measured is obtained according to the screen resolution of the intelligent terminal and the length of the image of the object to be measured in a measurement direction, and a second pixel value occupied by the reference object is obtained according to the screen resolution of the intelligent terminal and the length of the image of the reference object in the measurement direction; and the size of the object to be measured is calculated according to the obtained first pixel value, the second pixel value and the size of the reference object. According to the object size measurement method and system and the intelligent terminal, the size of the object can be more conveniently and rapidly measured, and measurement reliability and accuracy are high.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, system and intelligent terminal for measuring the size of an object. Background technique [0002] With the provision of technology and living standards, various smart terminals and their integration into our daily life have become an indispensable part. At present, the cameras used by smart terminals are only used to obtain morphological images of objects such as taking pictures and photography, which can no longer meet the needs of users. Many times, users often want to obtain the geometric dimensions of the objects to be photographed. For example, when we are shooting a certain building, although we can obtain the shape image of the building, but to know the geometric dimensions of its height and width, it is usually measured directly, which will be very troublesome.

Problems solved by technology

At present, the cameras used by smart terminals are only used to obtain the shape images of objects such as taking pictures and photography, which can no longer meet the needs of users. In many cases, users often want to obtain the geometric dimensions of the objects to be photographed.

For example, we are shooting a certain building, although we can obtain the shape image of the building, but to know the geometric dimensions of its height and width, it is usually measured directly, which will be very troublesome

[0003] At present, the schemes on the market that use the optical principle of the camera to measure the size of the object are based on the direct distance from the center of the optical lens to the object to be measured, and then combine the imaging pixels and focal length of the object to be measured to calculate the size of the object to be measured. The accuracy of this measurement method is relatively poor, because when the object to be measured is not perpendicular to the central optical axis of the camera, because of the included angle, it is easy to cause inaccurate measurement results of the geometric size of the object to be measured, and the reliability is low
