the tilt

Single-lens tilt photogrammetry is an effective method to obtain real-life 3D models. For small-scale, low-cost real-life 3D modeling, the traditional multi-lens tilt photography system had limitations due to load, cost, flight control, and other issues. At this time, single-lens tilt photogrammy showed its advantages. In terms of operation, the single-lens tilt photography system adopted the "well" shaped aerial flight operation method. The lens was pointed at an angle, and the data was collected by dense flight routes and "well" crisscrossed flight, so as to quickly and effectively obtain the image and texture features of the ground objects. With the help of data processing software, such as the use of drone butler software to set the flight aerial photography control parameters, based on Smart3D Capture software multi-view vision algorithm (PM VS) and motion structure recovery algorithm (CHF), etc., 3D modeling was quickly realized. In terms of application fields, in addition to large-scale maps, the results could also be used for 1:500 cadastral survey, real estate registration, geological disaster analysis, public security emergency fire protection, smart city, belt road planning and design, Urban area reconstruction, cultural relics protection, etc. And through the single-point accuracy test, it can meet the requirements of large-scale aerial photogrammetry industry standards, showing the advantages of low cost, high efficiency, and high accuracy in small-scale three-dimensional modeling projects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Xin Mi had used drone tilt photography technology in some projects. For example, in the construction of the Yunmeng Mountain Bridge in the reconstruction project from Xinzheng Airport to Xinmi on the S317 line, the project department and Zhengzhou University jointly set up a scientific research team to use the drone tilt photography technology to tackle the technical problems. The drone tilt photography technology was a technology that used a drone equipped with specialized tilt photography equipment to capture ground targets from multiple angles and directions, and then generated a three-dimensional model through post-processing. It had the following characteristics: 1. High efficiency: It can quickly and efficiently collect a large amount of image data, shortening the data collection and processing cycle. 2. High precision: Able to obtain texture information from multiple angles to improve the accuracy and authenticity of modeling. 3. Low cost: Compared to traditional 3D modeling methods, it does not require a lot of manpower, material resources, and time resources. 4. flexibility: Able to collect data from complex or difficult to access areas, making modeling work more flexible and convenient. 5. Rich data: Able to obtain a variety of information including position, height, texture, color, etc., providing a rich data source for subsequent analysis and application. 6. Expandable: It can be combined with virtual reality (VR), augmented reality (AR), geographical information system (GPS) and other technologies to expand the scope of application. The modeling process included: 1. Aerial route planning: Plan according to the size, shape, terrain, and other factors of the modeling area to ensure efficient coverage of the target area. 2. Aerial photography mission: Use a drone equipped with an inclined camera system (usually including the top and four inclined side cameras, with an inclination angle between 15° and 45°) to take multi-angle shots to obtain high-resolution and high-precision image data. 3. Collect and process data: Use the drone to fly to obtain the BOSS data and raw image data, and perform quality inspection. 4. Automatic modeling: import image data, GPS data, camera parameters, image control point coordinates, etc. into the automatic modeling software ContextCapture for real-life 3D model reconstruction. 5. [Model modification: Modifies the 3D reality model formed and performs quality inspection using point measurement information.] In the mountain landscape planning of Xiangshan Village in Xinmi City, based on the image data collected by the Phantom 4 MDT drone, the landscape planning and design were carried out by using the software such as ArcGIS and ContextCapture Center, which effectively solved the problems of complex topography, large vertical height difference, ecological sensitivity, and chaotic skyline in the rural mountain landscape planning. This also reflected the specific application results of the drone tilt photography technology in Xinmi. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The drone tilt photography technology could collect images from different angles at the same time by installing a tilt camera (commonly used five lenses) on the same drone platform. It could fully perceive complex scenes in a large-scale, high-precision, and high-definition manner. The data generated by the professional data processing process could directly reflect the appearance, position, height and other attributes of the ground objects, providing a guarantee for the true effect of the aerial survey results and the precision of surveying and plotting. For example, when carrying out aerial survey operations in a certain area of Hui County, this technology could be applied to the measurement of flat terrain and dense residential buildings. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Yuzhou used the drone tilt photosurveying technology in the on-site verification of the mining rights owner's exploration and mining information publicity. In addition, the drone tilt photography technology generally collected images from five different angles (tilt angle between 15° and 45°) by deploying multiple sensors in the drone aircraft. It could be used to obtain rich texture information on the side of the object, subverting the limitations of the previous orthophoto images that could only be shot from a vertical angle. This technology could integrate traditional aerial photography and close-range measurement technology. Based on the collected images combined with related software (such as Inpho, Pix4Dmapper, CC, DJZitu, etc.), real-life 3D modeling could be carried out. The process included drone shooting, aerial encryption, adding control points, model reconstruction, model modification, and other links. In the spatial triad encryption, the feature points of the images from five perspectives were calculated and extracted, and the same name points were matched to determine the relationship between the images. The control points could be added before and after the spatial triad encryption, which could save processing time. Model reconstruction included triangulated network generation (using the triangulated network calculated by the spatial encryption to generate a 3D model white model) and texture fitting (selecting a reasonable texture fit according to the shape and position of the 3D model to obtain a real-life 3D model). The 3D model modification included geometric modification and texture modification. There were corresponding modification operations for possible problems with the ground and road surface. Before the 3D modeling, it was necessary to refer to the 1:500, 1:1000, and 1:2000 Topographic Maps Aerial Photographic Regulations (GB/T 15661 - 2008) to ensure accuracy and specifications. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
