POSITIONING AND ORIENTATION METHOD, APPARATUS, AND DEVICE

A method includes the following steps: obtaining a first status of an object, where the first status includes a first position and a first pose; obtaining a second status of the object through inertial navigation by using the first status as a start point, where the second status includes a second position and a second pose; obtaining a third pose of the object through initial alignment; and providing inertial navigation for the object by using the third pose and the second position as a start point. A positioning and orientation apparatus and a positioning and orientation device are further provided. The second pose is replaced with the third pose obtained through initial alignment.
