(1) Introduction of UAV data processing software Pix4Dmapper
Pix4Dmapper (formerly Pix4UAV) is the automatic fast UAV data processing software of Pix4D Company of Switzerland. It is the unique UAV data and aerial image processing software that integrates automatic, fast and professional precision. Quickly create thousands of images into professional, accurate 2D maps and 3D models without the need for expert knowledge and manual intervention. The software can quickly acquire point clouds from aerial photography using the principles of photogrammetry and multi-objective reconstruction. Data and post processing. The processed application can benefit different industries, such as surveying and mapping, cultural relics protection, mining and so on. Application areas: aerial survey mapping, disaster emergency, safety law enforcement, agriculture and forestry monitoring, water and flood control, power inspection, marine environment, university research, military and other fields
Four advantages of Pix4Dmapper:
Specialization and simplification--The PIX4D mapper brings photogrammetry to a new era. The whole process is completely automated and with higher precision, which truly turns the drone into a new generation of professional measurement tools. Simply operate and without the need for expert knowledge, the flight controller can process and view the results and send the results to the end user.
Empty three, accuracy report - PIX4D mapper automatically calculates the original image outer orientation element through software. Automatically calibrate images using PIX4UAV technology and regional network adjustment techniques. The software automatically generates an accuracy report that can quickly and correctly assess the quality of the results. Provides detailed, quantitative automatic air 3, regional network adjustment and ground control point accuracy.
Fully automatic, one-button--PIX4D mapper does not require IMU, just the GPS position information of the image, it can be fully automatic one-button operation, no need to manually process the drone data. Native 64-bit software can greatly increase processing speed. Automatically generate orthophotos and automatically inlay and evenly splicing all the data into one large image. Image results can be displayed using GIS and RS software.
Cloud data, multi-camera - PIX4D mapper can process up to 10,000 images simultaneously using its own unique model. Can process images taken by multiple different cameras, and combine multiple data into one project for processing
(2) Calculation characteristics of data processing software for drones
Pix3Dmapper supports up to 10,000 images simultaneously, processing data from different cameras in the same project, multiple times, more than 2000 data fully automatic processing - intuitive and convenient interface, easy to add GCP - fast results map (DOM, DSM, etc.) The graphics workstation faces such intensive large-capacity aerial image file reading, compression storage, conversion, conversion, image reconstruction and other calculation operations in order to achieve fast, fully automatic processing purposes, the computer hardware configuration requirements are very high, from a hardware perspective, It involves all aspects of the hardware, the workstation hardware that has a significant impact on the processing speed:
(1) CPU frequency and number of cores (2) Memory capacity (3) Hard disk read and write bandwidth (4) CUDA architecture graphics card
The following is the performance of the hardware accessories provided by the manufacturer at each stage.
CPU | RAM | hard disk | Graphics card | |
first step | Very important . In some sub-processes, all cores can be used In other applications, there is only one core processing mode | Low usage rate | Low usage rate | useless |
Second step | Very important All cores are called | Very important All resources are used | Low usage rate | Low usage rate ( when selecting processing ) |
third step | Low usage rate | High usage rate | Very important Hard disk speed determines processing speed | useless |
rayCloud | Low usage rate | High usage rate | Low usage rate | Very important |
