Собираю тут дрон в путешествие, примерил крепление для GoPro. На простых FPV-дронах присутствие GoPro — обычное явление. Курсовая камера обычно не слишком высокого качества, и для окончательного видео ведут запись отдельно. Но зачем это на DJI, у которого и так камера с хорошими характеристиками?
Всё дело в стабилизации. С одной стороны, у GoPro на борту алгоритм Hypersmooth, который неплох, но не превосходит бортовой же алгоритм, встроенный в DJI. По крайней мере, разница совершенно точно не стоит добавочных 200 грамм веса и добавочных денег на покупку GoPro.
Но всё меняется, когда речь заходит о постобработке. GoPro пишет данные с гироскопа, синхронизированные с видеорядом, то есть угол наклона и другие движения можно вычислять не с помощью анализа изображения, а просто знать действительные значения в момент съёмки. Это позволило им выпустить программу ReelSteady, которая стабилизирует, как боженька. Ничто даже близко не подобралось к ней. Результат стабилизации невероятно офигенный и на три головы превосходит абсолютно все другие решения на рынке. Из-за этого многие владельцы DJI FPV, как и я, прикручивают на свой дрон GoPro, жертвуя маневренностью и полетным временем (а в случае аварии ещё и дополнительными деньгами).
Очень странно, что компания DJI сама не сделала ничего подобного: гироскоп в системе есть, алгоритм стабилизации известен — да, существует опенсорсная альтернатива ReelSteady под названием GyroFlow, работает ничуть не хуже. Но факт остаётся фактом: стабилизация на основе гиро-данных на световые годы впереди всего остального. Она, конечно, требует изрядных вычислительных ресурсов и не может быть произведена прямо на борту дрона или экшен-камеры. Даже мощный компьютер справляется не в реальном времени. Тем не менее, для получения действительно качественного результата это всё оправдано.
Я пока ни разу не пробовал сам летать с GoPro. Если не убьюсь о первую же скалу в Карелии, вы сможете увидеть результат через пару недель.

Russian rescuers immediately leave for the areas where people may still be trapped under rubble. The EMERCOM's rescue dogs are able to investigate thousands of m² of affected territory daily.
The airmobile hospital of the Ministry of Civil Defense, Emergencies and Disaster Relief of the Russian Federation 🇷🇺 (#EMERCOM) has begun working in full in the central part of the city of Mandalay 🇲🇲, an area hit by the earthquake.
Over 20 doctors are providing medical assistance to those in need. Therapeutic, surgical and intensive care units have received the first patients. The hospital will operate around the clock. The psychologists are also taking part in the mission.
🚑 The airmobile hospital is capable of operating autonomously for at least 14 days while receiving up to 200 patients a day. Meanwhile, its in-patient facility has 50 beds. The hospital has the necessary equipment for even the most complex surgeries.
❗❗❗
The Ministry of Civil Defense, Emergencies and Disaster Relief of the Russian Federation 🇷🇺 (#EMERCOM) has formed the largest group of rescuers to provide assistance to the population of Myanmar.
A total of 264 Russian rescuers are currently involved in eliminating the consequences of the strongest earthquake in Myanmar.
