How to import camera images with OpenCV?
(Stream_FreeRunLockBuffer)

OpenCV is an open source computer vision library. OpenCV has image taking feature but it does not support the camera standard of USB3 Vision and GigE Vision.
This material introduces the procedures to make image of USB3 Vision camera and GigE Vision camera based on "Stream_FreeRunLockBuffer" sample code by using TeliCamSDK among the methods of taking them as OpenCV structure or class object.

FAQ (2019/12/18)

What should we do if the duplicated camera image is displayed on multiple network?

If the camera is used with single system (PC) which has multiple network adapter, image might be displayed on each network adapter.

How to import camera images with OpenCV?
(GrabStreamSimple))

OpenCV is an open source computer vision library. OpenCV has image taking feature but it does not support the camera standard of USB3 Vision and GigE Vision. This material introduces the procedures to make image of USB3 Vision camera and GigE Vision camera based on "GrabStreamSimple.cpp" code by using TeliCamSDK among the methods of taking them as OpenCV structure or class object.

What is a Sequential shutter?

Sequential Shutter is a function for capturing images of a target object under multiple camera settings, for example, changing exposure time, gain, image offset, and so on.

FAQ (2019/9/17)

What should we do if a camera is not recognized by viewer software "TeliU3vViewer"?

In case of connecting BU/DU camera with PC, the camera may not be always recognized in viewer software "TeliU3vViewer". In such a case, we will explain how to check and replace the driver using device manager.

FAQ (2019/8/20)

How to use external trigger signal stably?

External trigger signal cannot work stably with affection of external noise. "Anti glitch" and "Anti chattering" function in the camera are recommended for such case. These functions can be set with our software development kit of "TeliCamSDK".

FAQ (2019/7/23)

How to run 32bit applications on 64bit Windows?

32bit applications developed with our software development kit of "TeliCamSDK" run on 64bit Windows.
64bit Windows OS has emulation layer of "WOW64" to run 32bit applications. This document describes the preliminary procedures and method of installation to run 32bit applications developed with "TeliCamSDK" on 64bit Windows.

FAQ (2019/6/18)

Requirement for copying "TeliCamSDK" components

The installer of software development kit "TeliCamSDK" conducts copy of various files (TeliCamSDK components) to specified folder, edition of environmental variables, writing information to registries etc. This material describes the necessary conditions to copy components of "TeliCamSDK" with installer of user applications etc.

FAQ (2019/5/21)

What is an XML Load Error?

"XML Load Error (0x101)" means error status returned from "camera open function" in case that "GenICam GenApi library" fails in loading camera information when camera is opened using TeliCamSDK.

FAQ (2019/4/15)

How to use LUT

LUT (Look Up Table) feature is a feature to convert input signal value to arbitrary value using look up table inside the camera. User application can modify the contents of look up table freely. Typical applications of LUT are gamma correction, image thresholding, positive-negative reversal.

FAQ (2019/3/19)

Corrupted image
(e.g. BU1203MCF)

This document shows how to get normal images when the following corrupted images are acquired.

FAQ (2016/8/16)

How to use ImageBuffer mode
(BU / DU series)

ImageBuffer mode is one of the camera imaging modes. Images shot by a camera will be accumulated to the image buffer in the camera without being transferred to PC. PC application can read out these images in the image buffer of the camera at any desired moment.
This document explains ImageBuffer mode and its usage.

FAQ (2016/8/16)

How to detect frame loss
(BU / DU series)

Frame lost means that an application fails to receive some of the frames continuously sent by a camera.
This might be caused by various elements such as camera, communication line, USB adapter, device driver or API (DLL).
Frame lost can be detected by checking BlockID of image received.
This document contains how to detect a frame lost and tips to prevent it.

FAQ (2016/8/16)

PixelFormat, PixelCoding, PixelSize
(BU / DU series, BG series)

PixelFormat is a value to indicate pixel data format of the image sent by the camera. It is standardized by Pixel Format Naming Convention (Association for Advancing Automation). (It is defined differently from Bitmap of PixelFormat.)
This document describes PixelFormat information which is useful with TeliCamSDK.

FAQ (2019/3/19)

How to get PixelFormats available in a camera
(BU / DU series, BG series)

PixelFormat is a value to indicate pixel data format of the image sent by the camera. (It is defined differently from Bitmap of PixelFormat.)
PixelFormat to set on the camera varies depend on the camera.
This document describes how to get PixelFormat list in detail with sample code.
