Description

Technical Field

[0001] The present application relates to the field of drones, and more specifically, to a real-time processing system for drone image data for surveying and mapping. Background Art

[0002] At present, most surveying and mapping still uses manual surveying and mapping. After the field data is collected, the collected data is organized and analyzed and integrated before drawing. This method is time-consuming, material-consuming, and labor-intensive, and is prone to errors, resulting in an inequality between labor and results and certain financial losses. For this reason, existing technologies have gradually begun to use drones in the field of surveying and mapping, using drones to shoot images to assist in surveying and mapping work.

[0003] The transmission of drone image data usually relies on radio wave transmission technology, including wireless modules or antennas, to ensure good signal strength and transmission distance even in complex environments. However, existing wireless modules and antennas are generally installed in specific parts of the drone, such as the wing tip, abdomen or head, to avoid interference of the signal from the body structure.

[0004] In existing real-time data processing systems, directional antennas are generally used to ensure longer communication distances and better signal strength. However, directional antennas usually have an obvious radiation direction, which results in poor data transmission quality when the drone is surveying and shooting in other directions. If omnidirectional antennas are used, there is a problem of shorter data transmission distance.

[0005] Therefore, this application proposes a real-time processing system for drone image data for surveying and mapping to solve the above technical problems. Utility Model Content

[0008] Furthermore, a partition for placing the data box is fixed in the middle of the data transmission platform, and a plurality of balls are embedded in the edge of the lower end surface of the data box, and the balls abut against the partition in the middle of the data transmission platform.

[0009] Furthermore, a primary protective cover is fixed to the top of the fixing plate, and a secondary protective cover is slidably mounted on an end surface of the primary protective cover away from the fixing plate.

[0010] Furthermore, a second motor is fixed to a side of the top of the fixing plate away from the directional antenna, and a shaft of the second motor is connected to a screw that drives the secondary protective cover to translate and slide.

[0011] Furthermore, the screw rod horizontally passes through the top end of the fixing plate and is parallel to the upper end surface of the secondary protective cover, and a driving ear for the screw rod thread to pass through is fixed to the upper end surface of the secondary protective cover.

[0012] Furthermore, the total length of the primary protective cover and the secondary protective cover is not less than the length of the directional antenna.
