opencv - Which algorithm or library can I use for detection and measuring box or boxes dimension

Question

I am currently working on a camera 3D realsense camera that detection and calculate the box or boxes dimension.

I am new in computer vision. I first worked on i just work on detection objects detection with color or without color to get a basic understanding. Using C++ and openCV, I want to managed to get the corners (and their x y z pixel coordinates) of the square using smoothing (remove noise), edge detection (canny function), lines detection (Hough transform) and lines intersection (mathematical calculation) on an simplified picture (uniform background).

Now is my question: do you have any direction/recommendation/advice/literature about dimension calculation of box. https://www.youtube.com/watch?v=l-i2E7aZY6A

i am using c++ and opencv with Intel realsens 3D camera. thanks in advance((-_-))

Answer 1

ボックスのカラー イメージ ピクセル座標を取得したら、投影インターフェイスのメソッドを使用して現実世界の座標 (ドキュメントでは頂点またはカメラ座標とも呼ばれます) を取得し、単純なピタゴラスを使用してポイント間の距離を mm 単位で計算します。 .

RealSense の経験がない場合は、ドキュメントを読み、SDK に含まれているサンプル アプリに目を通すことをお勧めします。
