METHOD OF DETERMINING DEFORMATION OF HOUSING OF OBJECT OF MAINLY SPACECRAFT Russian patent published in 2019 - IPC G01B11/16 G01B21/32 

FIELD: methods of process control.

SUBSTANCE: invention relates to methods of technological monitoring of equipment. Method of determining deformation of an object body, primarily a spacecraft, involves measuring an acute angle α between the direction from the landmark on the surface of the object to the illumination source and the normal to the plane tangent to the surface of the object at the reference point, acute angle measurement β between the optical axis of the shooting equipment installed on the object and the direction from the filming equipment to the lighting source, comparing said angle with a given value determined by the field of vision of the survey equipment, changing the orientation of the housing of the object until reaching an angle α of specified value, and angle β value exceeding the value compared to it, performing a series of landmark photographs and determining deformation of the object body by displacement of the landmark image on the images. Additionally measuring angle γ between normal to said plane and direction from landmark to recording equipment, value of angle is controlled δ between projections of directions from landmark to filming equipment and to source of illumination on said plane, at said change of orientation of the housing of the object, the orientation of the object at the moments of survey is changed to exceed the specified value, and with the said angle comparison β said angle is compared with half-opening of field of vision of filming equipment.

EFFECT: technical result consists in excluding interference from glares on images of landmarks performed for determining deformation of the housing of the object.
