FIELD: information technology.
SUBSTANCE: projection camera projects array of spot electromagnetic rays to the measured spatial region. Each of these rays contains information that identifies uniquely this ray and is expressed in the form of code and is connected functionally with equation of line of this ray movement. These rays are fixed with the reading device in such spatial region where they can be uniquely identified using codes containing in these rays. Thereby, if the codes of at least two different rays will be registered in the N point belonging to defined zone, than the coordinates of the N point respectively chosen system of coordinates are found as an answer to the set of equations of line. However, performance of reading devices is synchronised.
EFFECT: digitalisation of the objects surface points in one working cycle.
