Problems solved by technology
Ordinary laser ranging technology can only obtain the distance from the rangefinder to the target point, or measure and calculate the length of the right-angled side through the Pythagorean theorem, but it is powerless to measure the distance, azimuth, and inclination of any two points in the distance

Embodiment Construction
[0029] The invention will be described in further detail below in conjunction with the accompanying drawings, which is an explanation rather than a limitation of the invention.
[0030] The range finder with the function of measuring azimuth and inclination has already possessed the conditions from the realization scheme. Firstly, the 3-axis magnetoresistive sensor and the 3-axis acceleration sensor for measuring azimuth and inclination angle are cheap and convenient to purchase. It needs to be integrated with the hand-held laser range finder on the market to realize the required functions. The specific implementation plan can also refer to the patent "a digital geological compass for multi-function measurement (inventor: Ma Qingxun, patent number: 201320069931.8) ". There is YHL90 / 360J intrinsically safe ranging compass for mines produced by Xi'an Ruitai Company on the market.

The invention provides a method for remotely measuring a distance between two arbitrary points based on laser ranging and azimuth and dip measurement. A distance measurement instrument adopted in the method needs to have a magnetic sensor and an acceleration sensor to measure an azimuth angle and an oblique angle, when the distance, the azimuth and the dip angle of two arbitrary points are measured, a measurement starting point of the distance measurement instrument is basically kept unchanged, the distance, the azimuth and the dip angle from the measurement starting point to two target points are respectively measured and recorded, and the distance, azimuth and dip angle of the two target points can be calculated by virtue of triangle three-dimensional geometric operation. Although the method for remotely measuring the distance, azimuth and dip angle of two arbitrary points has certain operation errors, the measurement working efficiency can be greatly increased, the method is suitable for the data measurement of two target points which cannot be reached or for the data measurement when an obstacle exists between the two target points, and the application range of the traditional laser distance measurement instrument is enlarged.
Description
[0001] Technical field: [0002] The invention relates to a remote measurement method for any two-point distance based on laser ranging and azimuth and inclination measurement. The method is widely applicable to the needs of non-contact measurement that requires fast and safe acquisition of any two-point distance in industrial and civil fields. [0003] Background technique: [0004] At present, laser ranging technology has been widely used in industrial and civil fields, and the application of sensors for measuring azimuth and inclination angle is also very common. Ordinary laser ranging technology can only obtain the distance from the rangefinder to the target point, or measure and calculate the length of the right-angled side through the Pythagorean theorem, but it is powerless to measure the distance, azimuth, and inclination of any two points in the distance . This requirement is common in situations such as dangerous situations, obstacles between two points, and the need...
