METHOD OF MEASURING LINEAR AND ANGULAR VALUES INDOORS Russian patent published in 2018 - IPC G01B11/00 G01C3/00 

FIELD: measuring equipment.

SUBSTANCE: method of measuring linear and angular values indoors is characterized by the use of a measuring device fixed to a tripod, which is capable of rotating 360 degrees along the vertical axis using an engine and has a laser range finder. Each digital unit of the measuring device is connected to a controller capable of writing data to memory and / or transmitting data in real time to the operator. And to measure the linear and angular values inside the room using a spacer tripod, resting the axis of rotation in the ceiling, and monostick in the floor. The measuring device is installed in a distance between the ceiling and the floor in approximately the middle zone of the room. The axis of rotation is set vertically with a deviation of the vertical line from the horizon level by no more than 10 degrees. Then readings of accelerometer are taken and, if necessary, placement correction of sight line of laser range finder on the horizon is provided, and then determination of distance from the axis of rotation to the wall is performed laser range finder, and data is recorded to memory or transferred to the computer. After this, the sighting line of the laser range finder is shifted to a certain angle in the horizontal plane. Wherein, rotation of the specified angle is taken place in automatic mode by stepper motor, and after each displacement digital controller takes the readings of accelerometer and the mechanical turning device, and optionally produce correction status line of sight laser range finder on the horizon. The obtained data on the rotation on a given angle and distance are recorded in memory or transmitted to the computer. This measurement cycle and the shift are repeated until the measuring device is rotated 360 degrees in the horizontal plane.

EFFECT: possibility of obtaining data on the area and shape of the ceiling, simplifying the measurement technology, simplifying the measuring instruments, accelerating the measurement of near-ceiling space.
