Processing data determination method, device and equipment and readable storage medium

The invention relates to a processing data determination method and device, equipment and a readable storage medium. First point cloud data representing the internal contour of a target space can be acquired; then, based on the second point cloud data of the customized furniture at the installation position in the target space, a first three-dimensional coordinate system of the customized furniture at the installation position is determined; on the basis of the first three-dimensional coordinate system and a second three-dimensional coordinate system where the first point cloud data is located, first processing data of a plate between the joint face of the customized furniture and the target space can be determined, and the joint face is a mounting plane where the customized furniture makes contact with the target space at the mounting position. In the virtual space of the target space, a more accurate three-dimensional coordinate system of the gap between the customized furniture and the wall surface at the
