Non-contact dip angle measuring device and method

Abstract

The invention discloses a non-contact dip angle measuring device and a method thereof. The non-contact dip angle measuring device comprises a distance measuring module, a dip angle measuring module, a microprocessor module, a display module, a power supply module and a main body, wherein the distance measuring module comprises two independent laser distance measuring units which send two parallel measuring paths from the measuring reference surface of the main body when measuring, and the two paths are sent to characteristic lines of a target to be measured; the distance measured by the two laser distance measuring units and the dip angle of the main body measured by the dip angle measuring module are processed by the microprocessor module to be output to the display module; two distance values can be equalized by adjusting the inclining angle of the main body; in addition, the main body, the two measuring paths and the characteristic lines of the target to be measured form a parallelogram; and the dip angle displayed by the display module is equal to the dip angle of the target to be measured. The non-contact dip angle measuring device and the method thereof, both provided by the invention, can conveniently carry out non-contact high-precision dip angle measurement for the target to be measured, particularly the target which is in a long distance, cannot be easily reached by human beings or has an imperfect measuring visual angle.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a non-contact inclination measuring device and method. Background technique [0002] The existing inclination measuring devices are mainly contact-type, by measuring the contact between the reference surface and the measured object, using a gravity vertical device (such as a weight) and an angle dial to read or use an inclination sensor to measure the inclination angle, this measurement method The measuring instrument and the object to be measured must be in contact. When measuring distant objects and objects that are not suitable for humans to approach (such as objects in dangerous environments such as high temperature and dust), it is necessary to make a large-scale angle conversion device (such as a T-square) for indirect measurement. The operation is very inconvenient, and the way of dial reading is also difficult to ensure the measurement accuracy. At present, there ar...

[0002] The existing inclination measuring devices are mainly contact-type, by measuring the contact between the reference surface and the measured object, using a gravity vertical device (such as a weight) and an angle dial to read or use an inclination sensor to measure the inclination angle, this measurement method The measuring instrument and the object to be measured must be in contact. When measuring distant objects and objects that are not suitable for humans to approach (such as objects in dangerous environments such as high temperature and dust), it is necessary to make a large-scale angle conversion device (such as a T-square) for indirect measurement. The operation is very inconvenient, and at the same time, it is difficult to ensure the measurement accuracy by the dial reading method

At present, there are also non-contact methods for measuring inclination angles, such as vision or image processing, but the inclination angle of the measured target must be completely within the visual angle of view of the measurer to measure, which has higher requirements for the measurement angle of view
