Abstract

The invention discloses a device and a method for measuring a spatial free attitude of a rigid object, and a method for analyzing data, and relates to a measurement technology. The device comprises a planar orthogonal four-directional cursor generation device and a linear array charge coupled device (CCD); and the linear array CCD is provided with a data output interface. In the invention, a position detector consists of a plurality of linear array CCDs, so the problem that a detector with a large planar array position cannot be substituted is solved, the measurement device is simplified and the same measurement precision within a measurement range can be guaranteed. By adoption of the method for processing the data, the measurement of a linear light position can reach the subpixel level under the condition of poor data quality; and finally, a systematic measurement result can reach a higher level.

Description

technical field

[0001] The invention relates to measurement technology. Background technique

[0002] The six-degree-of-freedom parallel platform is an important simulation test equipment for dynamic reliability research of various equipment such as aircraft, ships, and vehicle-mounted instruments. Its research is a precise and complex engineering science, involving machinery, computer control, and photoelectric measurement. and other technologies. The attitude measurement of the six-degree-of-freedom parallel platform is a typical multi-degree-of-freedom attitude measurement. The measurement objects are the amount of space movement and the amount of rotation around the space axis. Through the measurement of these parameters and inverse solution, the correct space attitude parameters of the platform can be obtained. , feedback to the control system can control it, so as to achieve the purpose of changing its attitude according to the requirements.

[0003] There are many f...
