Простейшую систему, использующую Axis Video API, может создать любой, кто имеет хотя бы малейшие навыки написания HTML страниц. А установив набор дополнительного программного обеспечения, можно создать достаточно мощную систему видеонаблюдения с возможностью записи видеоархивов, журналирования, просмотра архивов и т.п.

Статические изображения.

Для получения картинки с камеры достаточно ввести в браузере следующий путь: 

http://192.168.0.9/jpg/image.jpg

Примечание. 192.168.0.9 - это IP адрес, присваеваемый камере по-умолчанию. Если ваша камера имеет IP адрес отличный от 192.168.0.9, то используйте его.

Можно также запрашивать с камеры изображения с некоторым набором параметров. Для этого используется путь : 

http://192.168.0.9/axis-cgi/jpg/image.cgi?param1=xxx&param2=yyy&.....

Ниже приведен список параметров, которые можно использовать.

resolution=<string> Specify the resolution of the returned image, for example 800x600. Product-dependent. Просмотреть, какие значения поддерживает Ваша камера можно по адресу : http://192.168.0.9/axis-cgi/admin/param.cgi?action=list&group=Properties.Image.Resolution

compression=<int> Adjusts the compression level of the image. Higher values correspond to higher compression, i.e. lower quality and smaller image size. Может принимать значение от 0 до 100. В большинстве случаев оптимальным является значение 30.

colorlevel=<int> Sets level of color or grey-scale. Может принимать значение от 0 до 100. 0 = grey-scale, 100 = full color.

color=<int> Enables/disables color. Может принимать значения 0 и 1. 0 = black and white, 1 = color.

rotation=<int> Rotates the image clockwise. Product-dependent. Просмотреть, какие значения поддерживает Ваша камера можно по адресу : http://192.168.0.9/axis-cgi/admin/param.cgi?action=list&group=Properties.Image.Rotation

Пример получения картинки с заданным набором параметров: 

http://192.168.0.9/axis-cgi/jpg/image.cgi?resolution=1024x768&colorlrvel=45&compression=30

Если какой-то из параметров не задан, то используется значение по-умолчанию. Узнать какие значения используются по-умолчанию можно по адресу: 

http://192.168.0.9/axis-cgi/admin/param.cgi?action=list&group=Image.I0.Appearance

Значения по-умолчанию можно изменять. Для этого нужно указать action=update. Например : 

http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&Image.I0.Appearance.Resolution=512x384&Image.I0.Appearance.Rotation=180&ColorEnabled=no&Image.I0.Appearance.Compression=50

http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&ImageSource.I0.Sensor.ColorLevel=60

Видеопоток

Камеры позволяют получать непрерывный поток видеоданных. Этот поток может передаваться по двум протоколам HTTP и RTP.

HTTP

Jpeg

Поток представляет собой последовательность jpeg-файлов, разделенных специальной строкой-маркером. Такой формат передачи называется Multipart Jpeg или MPJPG. Чтобы получить видеопоток в данном формате, можно использовать следующий путь: 

http://192.168.0.9/mjpg/video.mjpg

Как и для статических изображений, для видеопотока можно задавать параметры. Для этого используется следующий путь : 

http://192.168.0.9/axis-cgi/mjpg/video.cgi?param1=xxx&param2=yyy&.....

Кроме вышеперечисленных resolution, compression, colorlevel, color, rotation можно еще указывать:

duration=<int> Specifies for how many seconds the video will be generated and pushed to the client. 0 = unlimited.

nbrofframes=<int> Specifies how many frames the server will generate and push. 0 = unlimited.

fps=<int> Using fps it is possible to specify the frame rate from the server. 0 = unlimited.

По-умолчанию все эти значения равны 0. Изменить значение по-умолчанию можно,например, так : 

http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&Image.I0.Stream.Duration=100&Image.I0.Stream.FPS=5&Image.I0.Stream.NbrOfFrames=1000

Некоторые браузеры понимают формат данных MPJPG и могут воспроизвести этот видеопоток. К таким браузерам относятся Netscape, Mozilla, Firefox, Galeon. Более подробно смотри на страничке Play MPJPG in browsers.

Такие распространенные программы как mplayer, mencoder, ffmpeg и ffplay могут сохранять и воспроизводить поток MPJPG. Смотри Video API And Client Applications.Ru.

Видеопоток MPJPG легко сохраняется при помощи некоторых утилит, например, wget или Reget. Файл с записанным потоком далее может быть воспроизведен или преобразован в другой формат (например, утилитой ffmpeg или mencoder).

В среде Windows можно применять ActiveX фирмы Axis. Найти его можно по адресу : http://www.axis.com/techsup/cam_servers/dev/activex.htm

Также существует ActiveX фирмы Elphel, который доступен по адресу: ....

Более подробную информацию о программах, библиотеках и т.п., которые можно использовать с Axis Video API можно найти на странице Video API And Client Applications.Ru.

Theora

RTP

Jpeg

Каждый jpeg-файл разделяется на множество пакетов размером меньше 1500 байт и передается по сети по протоколу RTP/UDP. Передача данных в этом случае существенно ускоряется, но при этом падает надежность передачи, что может приводить в перегруженных сетях к потере некоторого количества видеоинформации.

Multicast

Чтобы получить видепоток по RTP/Multicast достаточно установить специальную переменную : 

http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&Network.RTP.R0.AlwaysMulticast=yes

При этом будет сгенерирован видеопоток со значениями по-умолчанию для multicast IP адреса, порта назначения и TTL. Эти значения можно изменить следующим образом : 

http://192.168.0.9/axis-cgi/admin/param.cgi?action=update&Network.RTP.R0.VideoAddress=224.21.23.44&Network.RTP.R0.VideoPort=22222&Network.RTP.R0.TTL=90
SDP

Такой видеопоток может быть принят, записан или воспроизведен при помощи mplayer, QuickTime, vic (из пакета mush). Для этого нужно с камеры получить SDP-файл : 

http://192.168.0.9/mjpg/media.sdp

Сохраненный файл нужно передать на вход выбранной программы. Например: 

mplayer sdp://media.sdp

Примечание. mplayer должен быть скомпилирован с поддержкой библиотеки live555.com

RTSP

Оригинальная спецификация Axis Video API не поддерживает RTSP в режиме multicast. В камерах Elphel эта возможность реализована как расширение протокола.

Eyesis4Pi-393 is the newest generation of the full-sphere multi-camera systems for stereophotogrammetric applications.
  • The system is calibrated to compensate for optical aberrations allowing to preserve full sensor resolution over the field of view.
  • Distortion calibration is performed for precise pixel-mapping to automatically stitch images into panoramas, and also for photogrammetry and 3D reconstruction.  
  • There are 24 x 5MPix sensors in the camera head, resulting in 120 MPix image acquisition. Panorama image resolution after stitching is 64 MPix, the equirectangular projection is 14000x7000.
  • High-precision Inertial Measurement Unit IMU (ADIS 16375, 2400 samples per second) is integrated with the camera, as well as 5Hz GPS (Locosys LS20031) to provide precise position and orientation of the camera.
  • Images, synchronized with IMU and GPS data, can be recorded to internal Solid State Drives (SSD), external swappable SSDs or to a PC over the network.
  • Optionally Eyesis4Pi-393 camera system includes PC for image downloading and post-processing with pre-installed SDK and Free and Open Source Software for camera calibration, image acquisition and panorama stitching.
  • Eyesis4Pi-393 can be mounted on a car for outdoor panoramic applications or carried by a person, which lets successfully create panoramas of small and narrow spaces.*

Automated panoramic imagery and 3-dimensional panoramas are the 2 main applications of Eyesise4Pi-393 camera.
