The invention discloses a magnetic-stripe-like positioning method based on a ceiling-type two-dimensional code. The magnetic-stripe-like positioning method includes: collecting a two-dimensional code image; obtaining the rotation angle of the two-dimensional code, and picking up the center point of the image and a preset straight line According to the rotation angle and vertical distance, calculate the deviation value of the mobile platform relative to a single two-dimensional code; obtain the deviation value of the mobile platform relative to each two-dimensional code, and calculate the deviation of the mobile platform relative to the imitation magnetic strip track according to each deviation value value; adjust the pose of the mobile platform according to the deviation value until the deviation value is zero. The imitation magnetic strip positioning method based on the ceiling-type two-dimensional code of the present invention can effectively reduce the damage rate of the two-dimensional code guide track, reduce the difficulty of construction, and thereby reduce the cost. In addition, the invention also discloses a magnetic-strip imitation positioning device based on a ceiling-type two-dimensional code.
Description
technical field [0001] The invention relates to the technical field of space positioning, in particular to a method and device for imitating magnetic stripe positioning based on a ceiling-type two-dimensional code. Background technique [0002] In order to apply the mobile platform in automated production and warehouse management, it is required that the mobile platform can accurately identify the current location in order to transport items to the designated area. [0003] At present, the commonly used positioning methods for mobile platforms include magnetic track positioning method and two-dimensional code positioning method. The magnetic track positioning method uses a magnetic navigation sensor set on the mobile platform and a magnetic strip laid on the ground for positioning. The two-dimensional code positioning method uses a positioning camera on a mobile platform and a two-dimensional code on the ceiling or on the ground for positioning. [0004] As we all know, the...
