![]() ![]() Rails play an important role in the maintenance and repair of railway lines. ![]() Using the method in this study, the laser plane attitude can be quantified and accurately assessed on both sides, effectively resolving the problem with traditional methods that can only assess the laser plane attitude qualitatively and roughly, thereby providing a solid foundation for calibration and error correction of the measurement system. On this basis, laser coplanarity evaluation criteria were developed to determine whether the laser planes on both sides of the rails are coplanar. Real-time fitting of laser planes with three planar targets of different heights provides information about the laser plane attitude on both sides of the rails. This study proposes an evaluation method based on fitting planes in response to this problem. Currently, in the field of rail profile measurement, there are no effective methods for evaluating laser plane attitude, and it is impossible to determine the degree of laser coplanarity quantitatively and accurately. They are meant for real-world reliability.The non-coplanar lasers on both sides of the rail during full-section rail profile measurement based on line-structured light vision will cause the measured profile to be distorted, resulting in measurement errors. Temperature extremes, humidity, and clumsy handling will not harm Spectra Precision products. They are ruggedly designed to withstand harsh on-the-job conditions including drops from as much as three feet onto concrete rain mud even brief immersion. Spectra Precision products help provide control for elevation, grade, vertical alignment, and 90-degree layout for both interior and exterior construction.

This collection contains original, master, and reference videos documenting Robert Studebaker, inventor of the LaserPlane.įor more than 55 years, Spectra Precision has been an innovation leader in the construction industry worldwide. A complex instrument, the Laser Plane combines mechanics, optics, and electronics to solve civil engineering problems. The company now belongs to Spectra Precision. A factory was built to manufacture the planes. Studebaker began work in 1964 and worked with a salesman from Perkin-Elmer, the first manufacturer of lasers in the United States to create the Laser Plane. Robert Studebaker of Dayton, Ohio, invented, developed, and produced the Laser Plane, the first modern alternative to the liquid level.
