1. A computer-implemented method of automatic object dimension measurement by using image processing, comprising: obtaining depth image data of an object to be measured in a scene captured by a sequence of images comprising a current image; determining the camera pose used to capture at least the current image; accumulating image depth data as images from the sequence are obtained and in a global 3D coordinate system of the current image; obtaining an object pose comprising a position, size, and orientation of the object from an object memory; realigning the object pose to a camera coordinate system of the current image; and independently detecting and refining the object pose to update the object memory wherein independently refers to the realigning being performed by obtaining an existing object pose from the object memory without waiting for the updating of the object pose in the object memory.
