radiometric calibration

obtaining the character skeleton, you must first perform the calibration. Therefore, skeletoncapability needs to register two callback functions: calibrationstart and calibrationend, which are called at the start and end of the character calibration. (In earlier versions of openni, the interface name may change) [4] similar to [3], usergenerator. getposedetectioncap () obtains a posedetectioncapability, wh

binocular vision time is another thing.The main steps to achieve binocular ranging on OpenCV are: 1. Binocular calibration and calibration, access to the camera parameters matrix:The parameter matrix of two cameras is calibratedCvstereorectify performs binocular correctionInitundistortrectifymap to generate two image correction required pixel mapping matrixCvremap two images to be corrected separately 2.

you determine if the cable that you have installed exceeds the specified length? Microscanner Pro uses TDR technology to obtain accurate length measurement results to make it easier to determine whether the cable length meets the standard. 1th step, insert the network cable. Plug one end of the twisted pair (or known length) into the "MAIN" port on the micro-scanner, and the other end is vacant. The 2nd step is to calibrate the NVP value. NVP (nominal transmission speed) is the ratio of the spe

Each time the RDC increases by 4 steps, the RDC decreases by 3 steps; Vi. OCV/kulunmeter mutual

Recently to customers debugging a piece of CNC board, today customers bring a screen, and a USB touch screen chip connected to the screen. The screen will soon be ready for normal display. Touch screen in the core to find the USB touch screen driver, the kernel started after the USB turn of the touch screen is also normal to find, registered as event interface Events event0, CAT/DEV/EVENT0, touch screen has garbled output, The USB touch screen driver is interrupted and the acquisition data is re

color image as a preprocessing step to perform over-segmentation) Without an additional source of information could only apply to bilateral filter, not cross bilateral filter.Then we have to make a good distinction between bilateral filter and cross bilateral filter. Bilateral filterThe wiki explains: A bilateral filter is a non-linear,edge-preserving and noise-reducing smoothing the filter for images. That is, the two-sided filtering has three characteristics: nonlinearity, preserving edges,

Test oracle db iops Today, I need to test one database's iops and do something for oracle db's io test. How to test the db's iops? It can use oracle's pl/SQL package taht is dbms_resource_manager.calibrate_io. here is the introduction of that procedure. CALIBRATE_IO ProcedureThis procedure calibrates the I/O capabilities of storage. calibration status is available from theV $ IO_CALIBRATION_STATUS view and results for a successful
