Design a UAV based on OPS plane positioning system millimeter level rapid replacement battery take-off and landing platform, in order to achieve the function and operation feasibility of battery replacement, the following three main functions of research and design: 1. UAV precision landing 2. Accurate replacement of the battery 3. Remote control system. Through the use of Python language, the use of Opencv, Tensorflow and other visual processing, to achieve product intelligence, reliability. Products through the large battery unified electricity, as far as possible to reduce the occupation of public facilities. The workflow of the take-off and landing platform depends on four major systems: the all-round mobile system of the undertaking platform, the visual fixed bit and micro-correction system, battery replacement system, closed-loop control system.
