Stair measuring method based on three-dimensional photographic technology

Abstract

The invention discloses a stair measurement method based on three-dimensional photography technology. The method includes placing non-coded points, placing coded points, calibrating the camera correction plate and camera, placing the camera correction plate and taking photos, and importing the photos into software to establish a three-dimensional model. step. This method is simple and easy to implement, and avoids the disadvantages of difficult to guarantee measurement accuracy, time-consuming and labor-intensive, and low efficiency existing in traditional mechanical measurement methods.

Description

Technical field [0001] The present invention involves a method of measurement of data such as the length, width, height, and orientation of the stairs, especially a stairs measurement method based on three -dimensional photography technology. Background technique [0002] In real life, we often need to measure data parameters such as the length, width, height, and orientation of the stairs in order to be used for the implementation of certain engineering projects.In most cases, it is used to directly measure manually, that is, the measured ruler is used to measure a little bit, and then the obtained data is combined for further processing.However, there are great disadvantages of this traditional mechanical measurement method: 1. The accuracy of direct measurement with a ruler is difficult to guarantee.Because the actual measurement itself has system errors and random errors, coupled with the impact of the surrounding environment, and it is difficult to ensure the level and verti...

However, this traditional mechanical measurement method has great disadvantages: 1. It is difficult to guarantee the accuracy of direct measurement with a ruler

Due to the existence of systematic errors and random errors in the actual measurement itself, coupled with the influence of the surrounding environment, and it is difficult to ensure the horizontal and vertical of the scale in the actual measurement, the measurement benchmark is also changing at any time, and the final measurement error will be very large. Second, due to the poor measurement environment (such as lighting, space size, temperature, etc.) In some cases, due to the limitations of measurement conditions, the cost of direct measurement with a ruler is too high or even the method of direct measurement cannot be used to obtain the required staircase data; 4. The method of direct measurement is often time-consuming and takes up a huge amount of time. It is very easy to cause inconvenience to people on the floor (especially some elderly or disabled people) going up and down the stairs
