FIELD: information technologies.
SUBSTANCE: invention relates to the field of engineering land surveying and is based on computer processing of television image of controlled object contained in output video signal of video sensor. The device is composed of the following components: unit for extraction of line and frame sync pulses, unit for extraction of video frame points coordinates, comprising quartz generator and counters, unit of memory and transfer of coordinates into computer port, source of threshold voltage, amplitude comparator and unit of synchronisation of recording into memory.
EFFECT: reduced hardware and time expenditures.
