| 説明 | The previous test looked for changes on the Z axis only, of greater than 200, which is good at detecting a person waving their arms at their sides. In that case, the Z changes from the Z of the back wall to the z of their arms. This test attempts to find the arm's current location. The red colour appears when the Z has changed by more than 200 positively and should therefore represent the location most recently occupied by my hand/arm. The green is a negative change of less than -200 and should represent the current location. As you can see, there are double images of red and green which are framing my moving arm. This is because my arm is casting a shadow and the Z coordinate scan has areas of no data which are stored as some constant depth (probably 0 or infinite or maxint or something).I am also tracking smaller changes on the Z axis which have an absolute value larger than 10, but smaller than 200. I thought this would just be useful for moving my arms closer to and farther away from the camera, but as I'm not holding my arms rigidly to the XY plane, it also shows up with up and down movements as well. The red and green part more detects moving edges, whereas the blue gets the centre of my hand. Ergo, I think the smaller threshold is more useful for detecting movement. |
