Abstract
Indoor measurement has always been an important process of indoor acceptance, such as the measurement of room structure (depth, bay, height, and wall flatness). Traditionally, these quality assessments rely on manual labor, which is highly subjective and variable. Consequently, automated devices such as terrestrial laser scanners (TLS) have been increasingly adopted for this task, but they cannot be widely used in indoor measurement due to limitations such as high price, poor interpretability, and single sensor. This paper presents a novel low-cost multisensor-based indoor measurement device to compensate for these shortcomings. This research includes: (1) unique mechanical design that transforms sensor information into sparse 3D point cloud data (PCD); (2) plane segmentation based on sparse point cloud; and (3) window opening measurement based on edge detection in dynamic background and monocular camera self-calibration. The reliability of this device was verified through experiments, and the results demonstrated that the device can realize high-precision indoor measurements in less than 5 min for one room.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
