Abstract

A construction laser system includes a rotating laser with self-leveling and a laser receiver. The system performs a self-leveling recalibration process by which-the self-leveling is checked automatically for quality and the related calibration data is updated automatically. A sequence of N calibration measurements is defined, where N is greater than or equal to three. The calibration measurements are obtained by the rotating laser and the laser receiver with a respective azimuthal alignment of the stand while the position of the laser receiver remains unchanged. As part of each calibration measurement, one output signal dependent on the laser beam impingement position is detected. The respective output signals or specified impingement positions are evaluated in pairs correlated with the respective I-th azimuthal alignments. The quality of the beam leveling functionality is thereby checked. If the requirements are not met, the previously stored calibration data can then be updated automatically.

Description

technical field [0001] The invention relates to a construction laser system for working in construction and / or interior design, comprising a rotating laser and a laser receiver with improved functionality in terms of configuration complexity and speed of implementation, for determining the distance from the rotating laser Angle to see the direction in which the laser receiver is located. Furthermore, the invention relates to a corresponding method using a rotating laser and a laser receiver, wherein the determination of the direction in which the laser receiver is located from the point of view of the rotating laser is performed in an improved manner, and to a computer program product for implementing the method. Background technique [0002] It is known to use rotating lasers on construction sites (for example of buildings) or in road construction work and / or earthworks. In particular, rotating lasers are used in situations in which a laser beam (in the visible or infrared...
