FIELD: measurement equipment.
SUBSTANCE: invention relates to photogrammetric methods for detection of speed of objects movement during aeroballistic, terradynamic, impact, fragmentation and other types of tests. The method includes installation of photorecorders along the trajectory of the missile flight, arrangement of screens with applied scaling orthogonal grids and an axis of coordinates in the vertical plane along the sighting line in the field of photorecording. Reference marks are arranged in the field of photoregistration, screens are installed directly in the plane of firing, the axis of coordinates is matched with the sighting line. Prior to start of the missile, each photorecorder is used to make a photo of the appropriate section of each screen, then screens are removed, the missile is launched, and its two subsequent positions are photographed. One of images for each section of photorecording is made semitransparent and is applied one onto the other with matching of reference marks. The distance between two subsequent positions of the missile is defined on the basis of the scaling grid on the produced matched images.
EFFECT: invention makes it possible to exclude parallax impact, to increase accuracy of speed detection and manufacturability of process of measurement equipment preparation for testing.
