remap

问题 I'm using opencv remap function to map an image to another coordinate system. However, my initial tests indicate that there are some issues with the interpolation. Here, I give a simple example of a constant 0.1 pixel shift for a image that is 0 everywhere but at position [50,50]. import cv2 import numpy as np prvs = np.zeros((100,80), dtype=np.float32) prvs[50:51, 50:51] = 1. grid_x, grid_y = np.meshgrid(np.arange(prvs.shape[1]), np.arange(prvs.shape[0])) grid_y = grid_y.astype(np.float32)

问题 I want to distort and rectified my stereo images. For which I used Opencv 3.3 in Python 2.7. Code I used is : import cv2 import numpy as np cameraMatrixL = np.load('mtx_left.npy') distCoeffsL = np.load('dist_left.npy') cameraMatrixR = np.load('mtx_right.npy') distCoeffsR = np.load('dist_right.npy') R = np.load('R.npy') T = np.load('T.npy') imgleft = cv2.imread('D:\python\camera calibration and 3d const\left\left60.png',0) imgright = cv2.imread('D:\python\camera calibration and 3d const\Right

问题 I used the above and wrote this: <class name="umple.pts.domain.coreEntities.Stop"> <property name="StopName" sig="()Ljava.lang.String;"> <getter name="getName" sig="()Ljava.lang.String;" /> <setter name="setName" sig="(Ljava.lang.String;)Z" /> </property> <property name="StopId" sig="()I"> <getter name="getStopId" sig="()I" /> <setter name="setStopId" sig="(I)V" /> </property> </class> <class name="umple.pts.domain.coreEntities.Line"> <property name="LineName" sig="()Ljava.lang.String;">

问题 I'm using the remap function to map a irregular grid( 650 xyz-coordinates ) to a regular one ( 160x160 points from -5....5 step 1/160) but I can't seem to get it working. By the way the interpolation that I use is bicubic. Can someone please tell me if it's even possible to do it like this? thanks in advance. using namespace cv; using namespace POINTS; std::ofstream file; Mat src(400,3,CV_32F); Mat dst(160,160,CV_32F); Mat map_x; Mat map_y; int ind = 0; Mat matx( 400, 1, CV_32F, &pointsx );

问题 In Visual Studio 2010 Solution Explorer tree view, how can I remap the F2 key to Rename the Selected File rather than open Object Browser? 回答1: Do the following Tools -> Options Expand Environment and select Keyboard Type "File.Rename" into the text box Put the Focus on the "Press Shortcut keys" box and hit F2 Click Assign 回答2: I don't know about you, but in my copy of VS2010, F2 in the Solution Explorer DOES rename the file. What exactly do you have selected when you hit F2 ? 回答3: To enable

问题 Say user is going to search on 4 or 5 fields, ok? eg. he might want to search by firstname, email, mobile or even page number I want that codeigniter's url be like this: site.com/Controller/Method/variable1/value1/variable2/value2/variable3/value3 or site.com/Controller/Method/variable2/value2/variable3/value3/variable1/value1 (that they should have the same result) or in this format site.com/Controller/Method/variable2/value2/variable4/value4 some examples to clarify my question: site.com

问题 I want to remap the keyboard in the following mode: 2::ctrl 3::shift 4::alt 5::tab My problem is that pressing at the same time 3,4,5 (equivalent to pressing alt shift tab) does not work. After investigating a little I have found that ahk can not catch some keys when being pressed together (2,3,e OR 3,4,5). Here is my code through which I have found out this 2:: tooltip 2 sleep 500 tooltip return 3:: tooltip 3 sleep 500 tooltip return 4:: tooltip 4 sleep 500 tooltip return 5:: tooltip 5 sleep

问题 I am trying to warp an 640x360 image via the OpenCV remap function (in python 2.7). The steps executed are the following Generate a curve and store its x and y coordinates in two seperate arrays, curve_x and curve_y.I am attaching the generated curve as an image(using pyplot): Load image via the opencv imread function original = cv2.imread('C:\\Users\\User\\Desktop\\alaskan-landscaps3.jpg') Execute a nested for loop so that each pixel is shifted upwards in proportion to the height of the

问题 I saw the vim wiki tips and it says that in order to remap Esc to CAPS LOCK you have to edit the following windows code: REGEDIT4 [HKEY_CURRENT_USER\Keyboard Layout] "Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,01,00,3a,00,00,00,00,00 Is it possible to remap Esc to CAPS LOCK by only adding or modifying lines in the _vimrc? 回答1: I recommend that you use AutoHotkey for this. You can do a per-application hotkey change: SetTitleMatchMode,2 #IfWinActive,VIM CAPSLOCK::ESC return
