The single-light design of single-light mapping quadrotor drone is first reflected in the concentration of light in improving the accuracy of surveying and mapping. The light source output of a single lamp is more concentrated, which can accurately illuminate the surveying and mapping target area, reduce the dispersion and waste of light, and make the details of the target object more clearly presented under the action of light. This concentrated light can avoid the problem of uneven light superposition that may occur when multiple lights are irradiated, so that the edges, textures and other features of the object can be accurately captured, providing clearer original materials for subsequent image processing and data modeling, and ensuring the accuracy of surveying and mapping from the source.
The single-light design helps to reduce the mutual interference between lights. When multiple lights work at the same time, the angles and intensities of different light sources may be different, which is easy to form a complex light and shadow superposition on the target surface, resulting in unnecessary shadows or light spots, interfering with the judgment of the true form of the object. The single-light design can avoid this interference, so that the light forms a relatively uniform and stable illumination effect in the target area, so that the image captured by the surveying and mapping equipment is closer to the real state of the object, reducing the measurement error caused by light and shadow interference, and improving the accuracy of the data.
In terms of light intensity regulation, the single-light design is also more advantageous. The light output of a single lamp can be precisely adjusted according to the actual needs of the surveying and mapping scene. Whether it is fill light in a strong light environment or enhancement in a weak light environment, it can adapt to different light conditions more flexibly. This flexible control capability allows a single lamp to always provide appropriate lighting for the surveying and mapping target, ensuring that the details of the object can be clearly recorded in various environments, avoiding problems such as image blur and loss of details caused by too strong or too weak light, thereby improving the surveying and mapping accuracy.
The single-lamp design can also reduce the light path obstruction problem caused by the multi-lamp layout. When multiple lamps are installed, the lamps may block each other, resulting in some areas not being illuminated or insufficient light, forming a surveying and mapping blind area. The single-lamp design has a simpler layout, which can effectively avoid such obstruction, ensure that the light can evenly cover the entire surveying and mapping area, so that objects in every corner can be fully illuminated, reduce the loss of surveying and mapping data caused by blind spots, and ensure the integrity and accuracy of the surveying and mapping results.
The stability of a single lamp also has a positive impact on surveying and mapping accuracy. The structure of a single lamp is relatively simple. During the flight of a single-light mapping quadrotor drone, it is less affected by factors such as airflow and vibration, and the light output is more stable. Stable light can make the images captured by the mapping equipment at different times more consistent, avoid image brightness and color differences caused by light fluctuations, reduce errors in subsequent data splicing and processing, and improve the overall mapping accuracy.
When dealing with complex terrain and object shapes, the directional illumination capability of the single-lamp design is more advantageous. For uneven surfaces or complex structures, a single lamp can adjust the illumination angle to accurately focus on key parts and highlight the three-dimensional sense and detail features of the object. This directional illumination allows the mapping equipment to capture the three-dimensional information of the object more accurately, avoid the problem of weakened three-dimensional sense that may occur when multiple lights are illuminated, make the constructed three-dimensional model more in line with the actual shape of the object, and improve the accuracy and authenticity of the mapping.
In addition, the weight reduction brought by the single-lamp design indirectly improves the flight stability of the single-light mapping quadrotor drone. After the load of the single-light mapping quadrotor drone is reduced, it is easier to maintain a stable posture during flight and reduce the shooting angle deviation caused by the shaking of the fuselage. The stable flight posture allows the light from a single lamp to always accurately illuminate the target area, ensuring that the images taken by the surveying and mapping equipment are stable and clear, providing reliable guarantee for high-precision surveying and mapping data, and improving the accuracy of the entire surveying and mapping process in many aspects.
