Research on spatiotemporal geocoding method of UAV video stream
Addressing the issue of missing or low-accuracy spatial positioning information information in video mapping products,this paper proposes a spatiotemporal geocoding technology method for UAV video streams.A device for synchronous encoding of video streams in space and time was developed.A method and technical process for checking the synchronicity of spatiotemporal encoding using high-frequency display devices was established,capable of achieving video stream and spatiotemporal information fusion encoding results with a clock synchronization precision of the order of 10 ms.Real-time video mapping accuracy verification showed that the orthoimage planimetric accuracy is 4.69 m.The related achievements can provide real-time,high-precision,and high-resolution data support for scenarios such as emergency response.
