Problems solved by technology
The housing problem has always been a major issue in the national development strategy, but there are still many common problems in the current housing surveying institutions: the first is the professional quality of the surveyors, and many people without professional training work on the front line, which will inevitably lead to the measurement results. The credibility of the company has declined; there is also a mixed bag of housing measurement agencies, with high and low technical levels, resulting in unsatisfactory conclusions about the measurement results
, the current existing house measurement methods in the acceptance process are difficult to reach some measurement locations, low safety factor of surveyors, high risk, low efficiency of acceptance measurement, low data accuracy, and have an impact on the interests of owners and construction units

The invention discloses a house size measurement device based on a depth camera. The device comprises a rotatable and stretchable depth camera bracket which has a height and posture adjustment function, a computer which extracts a plane from depth information by adopting an RANSAC-based method and calculates out corresponding coordinate and angle information by using plane equation parameters, a depth input module which is arranged on the rotatable and stretchable depth camera bracket and is used for acquiring depth information in real time and transmitting the depth information to the computer, and a display screen which is in signal connection with the computer and is used for displaying the size information of the wall body and the house and performing human-computer interaction. The invention further discloses a house size measuring method based on a depth camera. The defects in the prior art are overcome. The house size measurement device and method based on a depth camera provided by the invention have the advantages of easy operation, time saving and labor saving and high safety, and can improve the measuring precision and speed.
Description
technical field [0001] The invention relates to the technical field of computer vision, in particular to a depth camera-based indoor dimension measurement technology of a house. It is mainly used for quick measurement of house size. Background technique [0002] At present, the commonly used house size measurement methods at home and abroad are traditional contact measurement methods, that is, using ordinary measuring rulers to measure. The housing problem has always been a major issue in the national development strategy, but there are still many common problems in the current housing surveying institutions: the first is the professional quality of the surveyors, and many people without professional training work on the front line, which will inevitably lead to the measurement results. The credibility of the company has declined; there is also a mixed bag of housing surveying institutions, with high and low technical levels, resulting in unsatisfactory conclusions about th...
