DEVICE FOR TECHNICAL VISION OF A SMALL UNMANNED AIRCRAFT

摘要

The utility model relates to devices for image analysis, namely, for determining the position and orientation of objects on the image to implement the spatial orientation of MBLA. The technical result of the utility model is to provide the possibility of recognizing lighting marks on the fixed elements of the base station. A technical vision device for a small unmanned aerial vehicle, containing a housing, with a video camera with a USB output attached to its outer surface, combined with a rangefinder, connected with a USB cable to the video input of the control unit located inside the housing, made on the basis of a microcontroller, characterized in that, that the microcontroller is capable of performing binary quantization of the image, for which a Gaussian filter is applied, which allows to automatically remove noise in the original image, convert the resulting image to grayscale, use the Sobel operator to highlight the boundaries of light technical marks, determine the coordinates and areas of the found marks, calculate sample characteristics of the found tags and identify tags by comparing their sample characteristics with the parameters of reference objects of images of lighting marks; at the same time, the microcontroller contains a microprocessor core connected via a system bus with a FLASH program memory, a SRAM data memory, a USB controller, an Ethernet controller, an LCD interface module, a general purpose input / output interface grouped into an eight-bit GPI / 0- I / O port, and an SD card connection module; while the video camera is configured to receive an ultra-high definition video stream. 5 p.p. f-ly, 4 dwg
