Embodiment Construction
[0045] The present invention provides a method and system for measuring large parts. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] This embodiment provides a method for measuring large parts, such as figure 1 As shown, the method includes:
[0047] S10. Determine the conversion relationship between the pixel coordinate system of each camera in the camera array and the world coordinate system.
[0048] Specifically, in the process of image measurement, in order to determine the relationship between the three-dimensional geometric position of a certain point on the surface of a space object and its corresponding point in the image, that is, the conversion relationship between the pixel coordinate...
