A Laser-Based Vertical Alignment Detection Device And Method
Technical Field
The invention relates to the field of laser ranging sensor, and specifically designs a laser-based vertical alignment detection device and method.
BACKGROUND TECHNOLOGY
In some scenarios that require equipment to be vertically aligned to a certain plane, such as electric drill drilling operations, a frequent drilling requirement is: use the electric drill to drill vertically on a wall, but due to the instability of manual operation and the inaccuracy of the human eye, it is easy to result in the tilting of the drilling direction, and the drill is not drilled vertically into the preset trajectory according to the requirements, resulting in construction errors. The traditional solution is to add auxiliary fixtures and other devices around the drill, which are often large and bulky, and need to be installed and fixed in advance, which is time-consuming and not conducive to efficient and portable drilling operations. There are also some by installing multiple laser rangefinders around the drill, through the measurement of the distance between the various directions is equal to determine whether the drilling is perpendicular to the drawbacks of this approach is that: the detection accuracy is proportional to the number of ranging modules, if you need a higher degree of accuracy will need to be installed in as many directions as possible to install more laser ranging modules, accordingly, the cost is high, the volume is large, and the laser ranging device measuring The speed of the laser rangefinder is limited, and the measuring efficiency is low.
Contents of the invention
The technical problem to be solved by the present invention is: a laser distance sensor vertical alignment detection device and method, which is dedicated to solving some of the above problems.
In order to achieve the above objects, the technical solutions adopted by the present invention are as follows:
A laser-based vertical alignment detection device includes a base, a control and image data processing unit fixed on the base, a laser generator fixed on the base, a prism position adjustment unit provided on the base, The laser angle deflection prism on the prism position adjustment unit, the CCD image acquisition unit fixed on the base, and the angle display unit fixed on the base; the above-mentioned control and image data processing unit are respectively connected to the laser generator and the angle display unit; the above-mentioned CCD The image acquisition unit is bidirectionally connected to the control and image data processing unit. The above-mentioned laser angle deflection prism is a truncated cone with the large diameter end close to the laser transmitter (2). The center line of the above-mentioned laser angle deflection prism and the laser axis of the laser transmitter are at the same time. On one line, the above-mentioned prism position adjustment unit is used to adjust the laser angle deflection prism to move in the direction of the laser axis of the laser transmitter.
Therefore, the angle display unit is used to display the angle calculation result.
The control method of the vertical alignment detection device of the laser includes: the control and image data processing unit controls the laser generator to emit collimated circular laser; and the laser angle deflection prism angularly deflects the generated collimated circular laser. , so that the collimated circular laser and the target wall present a certain angle; according to the distance between the laser-based vertical alignment detection device and the target wall, the laser angle deflection prism position is adjusted by the prism position adjustment unit to obtain a suitable size The projected image, the CCD image acquisition unit collects the projected image data, and feeds the projected image data back to the control and image data processing unit; the control and image data processing unit calculates and processes the projected image data, and the control and image data processing unit calculates and processes the projected image data. The results are transmitted to the angle display unit, and the angle display unit displays the results of the calculation processing.
Further, the prism position adjustment unit includes a slidable slider and a handle. The slider is embedded in the base (7). The handle is connected to the slider through a long through hole on the base.
The invention also discloses a laser-based vertical alignment detection method.
