FIELD: measurement.
SUBSTANCE: invention relates to measurement of deformations of building structural elements. Object of the invention is a system for measuring deformations of at least one element of at least one analysed structure, comprising at least one mark (1) rigidly fixed on an element of the analysed structure, at least one receiving device (2), configured and programmed to record data associated with the position of mark (1) in digital form, processing unit (4) configured and programmed to process data associated with the position of mark (1) connected via a communication channel to receiving device (2), preferably through receiving unit (3), characterized in that label (1) comprises at least ten light-emitting characteristic points. Invention also includes a method of measuring deformations of the analysed structure, implemented in this system, this method comprises the following steps: recording and preferably primary processing of data associated with position of mark (1), receiving device (2) in digital form; transmitting said digital data to processing unit (4), preferably by receiving unit (3), which primarily compresses the obtained digital data prior to transmission thereof to processing unit (4); and is characterized by that label (1) is used, having at least ten light-emitting characteristic points, and knowing a reference model of characteristic points of mark (1), and knowing the reference position of the centre of mark (1) and the reference rotation of mark (1); virtual turn is used to define turn and position of mark centre (1) and to adjust reference model of characteristic points of mark (1) to digital data; displacement and rotation of mark (1) are determined by comparing turn and position of centre of mark (1), determined at stage c), with reference position of centre of mark (1) and reference turn of mark (1).
EFFECT: technical results are simplified design and increased functional capabilities.
