OpenCV: Open Source Computer Vision Library

Videoio Module

• This Videoio Module can be supported for both Opencv version 3.3.1 and 3.4.1 with both Linux and Windows OS.

APIs Introduced

• bool getDevices(int &devices);
• bool getDeviceInfo(int device, String &deviceName, String &vid, String &pid, String &devicePath);
• bool getFormats(int &formats);
• bool getFormatType(int format, String &formatType, int &width, int &height, int &fps);
• bool setFormatType(int format)
• bool get(int propId, double &min, double &max, double &steppingDelta, double &supportedMode, double &currentValue, double &currentMode, double &defaultValue);
• bool set(int propId, double value, double mode);

APIs Explanation

bool getDevices(int &devices);

• Get total number of camera devices connected to the port.

bool getDeviceInfo(int device, String &deviceName, String &vid, String &pid, String &devicePath);

• Get specific camera device information such Device name, Device path, VendorID and productID.

bool getFormats(int &formats);

• Get total number of video formats supported by the camera device.

bool getFormatType(int format, String &formatType, int &width, int &height, int &fps);

• Get video resolution, video format and fps supported by the camera

bool setFormatType(int format);

• Set the video format, resolution and fps to the device.

bool get(int propId, double &min, double &max, double &steppingDelta, double &supportedMode, double &currentValue, double &currentMode, double &defaultValue);

• Get specific UVC Property(Brightness, Contrast,...) minimum value, maximum value, current value, default value, steppingDelta, current mode and supported mode.

bool set(int propId, double value, double mode);

• Set specific UVC Property(Brightness, Contrast, Hue,...) value and mode.

OpenCVCam Command Line Application

• OpenCVCam command line application can be used to access the UVC settings, HID settings, Streaming and Image capture of any e-con System cameras in both Windows and Linux.
