Embodiment Construction

[0034] Certain embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In describing the present invention, certain detailed descriptions of related art have been omitted when it was considered that they would unnecessarily obscure the essence of the present invention.

[0035] figure 2 It is a laser imaging module for a non-contact measuring device according to one aspect of the present invention. Such as figure 2 As shown, the laser imaging module 100 according to one aspect of the present invention includes: a laser generator 110 for irradiating a cross-shaped laser beam 111 onto the object to be measured; a pair of cameras 120 and 130 for irradiating the object to be measured and a single mount 140 on which the laser generator 110 and the pair of cameras 120, 130 are mounted as a whole. The laser generator 110 may be installed in the housing 150 , which is integrally connected to the fixing member 140 su...

Abstract

The invention relates to a laser image module and a non-contact type measurement device using the same, in particular to a device for measuring the shape of an object by a non-contact method and a laser image module used in the device. According to some aspects of the invention, a cross laser beam radiates a laser generator on the object; and a pair of cameras which photograph the laser beam image of the cross laser beam radiating the object can be integrally installed on a single fixing piece, thereby realizing the measurement of the object without any rotation, obtaining distortionless three-dimension shape measurement data, and minimizing the cost of the non-contact measurement device at the same time.

Description

technical field [0001] The invention relates to a laser image module and a non-contact measuring device using the laser image module. More specifically, the present invention relates to a device for measuring the shape of an object to be measured in a non-contact manner, and to a laser imaging module used in the device. Background technique [0002] In order to reduce propulsion resistance and provide high-efficiency sailing, the outer panel of a ship is generally composed of a 10-30 mm thick curved plate with a complex non-developable curved surface. In order to form such a curved outer panel, a processing method called linear annealing is generally used in which the surface of the steel sheet is partially annealed with a gas burner or the like. The resulting plastic deformation, which may include out-of-plane angular deformation or in-plane shrinkage, can be used to machine the steel sheet into a desired shape. [0003] For structures such as the curved ship panels descr...
