Problems solved by technology
Especially in the existing room 3D model modeling technology, it often involves the translation operation of the furniture. For some special furniture, the position often depends on the stationary object, that is, when the stationary object changes, the moved 3D The height of the model should also change accordingly; but in the existing technology, the accuracy of the height is controlled by manual detection and manual setting, that is, when the operator finds that the static object of the 3D model has changed, the operator needs to Then reset the height of the moved 3D model according to the height of the new stationary object; this method of manual detection and manual setting is neither convenient nor accurate, which not only causes errors, but also greatly increases the user's understanding of 3D modeling. operating costs

Embodiment 1
[0042] Such as figure 1 As shown, the 3D model 1 of the stationary object is a TV cabinet, and the 3D model 2 of the moving object is a TV. The horizontal direction is X and the vertical direction is Y. After the TV is translated, the positional relationship between the TV and the TV cabinet is calculated as an example
[0043] Such as image 3 As shown, the system based on the height detector to automatically calculate the height of the 3D model after movement includes 4 modules, namely the 3D model builder, the 3D model displacement catcher, the 3D model height detector and the 3D model node coordinate calculator, where The 3D model builder transmits the coordinates of each node of the OBB bounding box of the moving object and the coordinates of each node of the OBB bounding box of the stationary object to the 3D model height detector; 3D model height detector; the 3D model height detector transmits the calculated vertical displacement coordinates to the 3D model node coord...

The invention discloses a system and a method of automatically calculating height of a 3D model after being moved based on a height detector, and belongs to the computer vision technology field. The system comprises four modules, which are a 3D model builder, a 3D model displacement capturer, a 3D model height detector, and a 3D model node coordinate calculator. By adopting organic cooperation among the various modules, a problem that when the 3D model climbs to another 3D model or falls from another 3D model, the height of the 3D model is required to be set manually is solved.
Description
technical field [0001] The invention relates to computer vision recognition technology, in particular to a system and method for automatically calculating the height of a 3D model after it moves based on a height detector. Background technique [0002] As people pursue a desire for a more realistic virtual reality experience, 3D virtual reality technology has also become popular. Especially in the existing room 3D model modeling technology, it often involves the translation operation of the furniture. For some special furniture, the position often depends on the stationary object, that is, when the stationary object changes, the moved 3D The height of the model should also change accordingly; but in the existing technology, the accuracy of the height is controlled by manual detection and manual setting, that is, when the operator finds that the static object of the 3D model has changed, the operator needs to Then reset the height of the moved 3D model according to the heigh...
