Cv2selectROI which can be used to select a single ROI bounding box.
Roi camera. It improves acquisition efficiency in live and sports application. For example in medical imaging the boundaries of a tumor may be defined on an image or in a volume for the purpose of measuring its size. ROI stands for Region of Interest.
The 8K ROI camera contributes to the reduction of camera setup relocation and. Part of my code is shown below. Astrojedi on 08 Jun 2016 - 0837 AM said.
It improves acquisition efficiency in live and sports application. It means that the data transfer rate for the camera is set for the entire scene. Multi-ROI plots lets you choose the plot type.
If the camera does not support scalable video modes the entire image is transferred from the camera to system memory. Cv2getOptimalNewCameraMatrix function gives an estimation of what would be the new camera matrix without having you to require to do a new calibration. Pan tilt and zoom operations can be used on each crop area so a single 8K ROI camera serves as four HD cameras.
An 8K ROI camera can be set with a maximum of four crop areas to obtain an HD image from each of the crop areas. It also eliminates the need to take up audience seats for the setup of multiple cameras. The four crop areas 1 to 4 can be individually controlled for pan tilt and zoom.
The 8K ROI camera system which was launched this year brings an automated workflow to your live production. There are two functions which can be used to select ROI or ROIs in OPENCV. You can specify a part of the image you are interested in so that the camera can optimize readout and data transfer.
