METHOD FOR CONTACTLESS MEASUREMENT OF SPEED AND MOVEMENT OF OBJECT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC G01P3/68 

FIELD: instrumentation.

SUBSTANCE: illuminated by a lighter the object to be checked is fixed at a rod travelling along the guides with horizontal mark. A video camera is set in respect to the checked object so that its optical axis is perpendicular to the plane of the object movement and oriented to the horizontal mark. Simultaneously with the start of the object's movement the video camera is switched on and records the movement of measuring bar marks in respect to the horizontal mark by frames, the values of measuring bar marks coinciding with the horizontal mark on the frames going one after another are compared, and the speed of the object is calculated taking into account the movement of the object and the video recording speed.

EFFECT: invention allows for the improvement of the registration of process dynamics and for simultaneous analysis of dynamics in different parts of the object to be checked and saving of the measurement results in visual form as separate frames.
