Measuring method and system based on image identification

Abstract

The invention provides a measuring method based on image identification. The steps are that: shooting the images of a reference object and a to-be-detected object in the same shooting window, wherein the distance of the reference object and the shooting window and the distance of the to-be-detected object and the shooting window are the same; respectively calculating the occupied pixel number of the reference object and the to-be-detected object in the images; identifying the reference object, and acquiring the actual data of the reference object; confirming the corresponding actual data of each pixel inside the images according to the actual data of the reference data; and confirming the actual data of the to-be-detected object according to the corresponding actual data of each pixel. Due to the fact that the images of the reference object and the to-be-detected object with the same distance to the shooting window are shot in the same shooting window, according to the known actual data of the reference object and the pixel number of the reference object in the images, the corresponding actual data of each pixel in the images are calculated, and then, the pixel number of the to-be-detected object is combined, and therefore the actual data of the to-be-detected object can be confirmed.

Description

technical field [0001] The invention relates to an image recognition method, in particular to a measurement method based on image recognition. Background technique [0002] Sometimes when we want to measure the length of an object, the moving distance or speed of an object, the measuring instrument is often not easy to obtain, or even if there is a measuring instrument, the measured object or the environment in which the measured object is located is not convenient for measurement. And with the development of the current society, people are paying more and more attention to the moving distance or moving speed of objects in a short period of time, such as the flying distance or speed of various balls, or the speed of a car while driving. [0003] However, current electronic devices, especially mobile devices, are equipped with camera devices, which have camera and video recording functions. And now image recognition technology is very mature. Therefore, various measurements...

AI Technical Summary

Problems solved by technology

Both of the above two methods need to measure the object distance of the object to be measured, which is then limited by the distance between the camera device and the object to be measured, that is, the object distance of the object to be measured

When the distance between the shooting device and the object to be measured cannot be determined, the above method cannot be used
