The form of the Q matrix is given as follows: In that image, cx and cy are the coordinates of the principal point in the left camera (if you did stereo matching with the left camera dominant), c’x is the x-coordinate of the principal point in the right camera (cx and c’x will be the … Read more
You need to create a recursive function: >>> def depth(d): … if isinstance(d, dict): … return 1 + (max(map(depth, d.values())) if d else 0) … return 0 … >>> d = {‘a’:1, ‘b’: {‘c’:{}}} >>> depth(d) 3
The correct answer is actually a comment on your question. The number given is actually a distance in millimetres. To get this number, you either need to use a skeleton joint and call DepthImageFrame’s MapFromSkeletonPoint or shift the raw short value right by DepthImageFrame.PlayerIndexBitmaskWidth. E.g. Skeleton using (var skeletonFrame= e.OpenSkeletonFrame()) using (var depthFrame = e.OpenDepthImageFrame()) … Read more
According to the documentation, the function imshow can be used with a variety of image types. It support 16-bit unsigned images, so you can display your image using cv::Mat map = cv::imread(“image”, CV_LOAD_IMAGE_ANYCOLOR | CV_LOAD_IMAGE_ANYDEPTH); cv::imshow(“window”, map); In this case, the image value range is mapped from the range [0, 255*256] to the range [0, … Read more
Python don’t have a great support for recursion because of it’s lack of TRE (Tail Recursion Elimination). This means that each call to your recursive function will create a function call stack and because there is a limit of stack depth (by default is 1000) that you can check out by sys.getrecursionlimit (of course you … Read more
Let’s say that you are using some transparent *.png image. Then this would help: new THREE.MeshBasicMaterial( { side:THREE.BackSide,map:texture, depthWrite: false, depthTest: false });
From the docs: Trying to pickle a highly recursive data structure may exceed the maximum recursion depth, a RuntimeError will be raised in this case. You can carefully raise this limit with sys.setrecursionlimit(). Although your trie implementation may be simple, it uses recursion and can lead to issues when converting to a persistent data structure. … Read more
You can increment the stack depth allowed – with this, deeper recursive calls will be possible, like this: import sys sys.setrecursionlimit(10000) # 10000 is an example, try with different values … But I’d advise you to first try to optimize your code, for instance, using iteration instead of recursion.
but I still don’t know whether or not the gl_FragCoord.z is linear. Whether gl_FragCoord.z is linear or not depends on, the projection matrix. While for Orthographic Projection gl_FragCoord.z is linear, for Perspective Projection it is not linear. In general, the depth (gl_FragCoord.z and gl_FragDepth) is calculated as follows (see GLSL gl_FragCoord.z Calculation and Setting gl_FragDepth): … Read more
Answer ConvertTo-Json has a -Depth parameter: Specifies how many levels of contained objects are included in the JSON representation. The default value is 2. Example To do a full round-trip with a JSON file you need to increase the -Depth for the ConvertTo-Json cmdlet: $Json | ConvertFrom-Json | ConvertTo-Json -Depth 9 TL;DR Probably because ConvertTo-Json … Read more
