[0050] In the past, when calculating the CD gain in machine vision gesture interaction, the gesture interaction was divided into two sets of maps, such as Figure 4 As shown: 1) The mapping between the movement of the hand in the operation space and the camera tracking result, here is called the hand tracking mapping, which can be measured by the input accuracy k, that is, in the upper physical space, the unit length in the camera image The number of pixels formed, available Calculated, it is determined by the hand tracking algorithm and the specifications of the camera; 2) The mapping between the tracking result and the cursor movement, which is called tracking cursor mapping here, can be used count. Among them, V c Indicates the moving speed of the cursor on the display screen, L is the resolution of the camera on the screen, and α is the horizontal or vertical field of view of the camera, such as figure 1 shown. U is the refresh rate of the screen, R is the tracking c...
