Embodiment Construction

[0055] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0057] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other ind...

Abstract

The invention provides a coding point coordinate correction method, system and computer-readable storage medium for measuring the motion attitude of helicopter blades. The method includes: constructing a measurement unit composed of first, second and third industrial cameras that are rigidly connected , the adjacent industrial cameras have a common viewing area and form the first group and the second group of binocular measurement units respectively; the first group and the second group of binocular measurement units are calibrated respectively, and the calibration results are obtained; the blades of the helicopter The code point is pasted on the lower surface, the reference code point is pasted on the reference object, and the three-dimensional coordinates of the reference coordinate point are calculated; during the blade movement process of the helicopter, the first and second industrial cameras respectively obtain two-dimensional images containing the code point, according to The calibration result is reconstructed into the three-dimensional coordinates of the coded points; the third industrial camera tracks the reference coded points in real time to obtain the motion postures of the first and second industrial cameras; and the three-dimensional coordinates of the coded points are corrected. The operation is simple, flexible and accurate.

Description

technical field [0001] The present invention relates to the technical field of optical measurement, in particular to a method, system and computer-readable storage medium for correcting the coordinates of coding points used in the measurement of the movement attitude of helicopter blades. Background technique [0002] At present, the visual measurement of the motion attitude of the helicopter blade is to paste the circular code point on the surface of the blade, and then based on the binocular stereo vision technology, the three-dimensional coordinates of the circular code point are reconstructed in three dimensions, and finally the three-dimensional coordinates of the circular code point are solved. Parameters such as blade attitude angle. The measurement scheme involves coding point recognition and center point pixel coordinate extraction, camera calibration, and coding point three-dimensional reconstruction technology. [0003] The above technical solution assumes that t...
