AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly two forms of visual detection and target positioning system. One is that the visual processing part is set on the ground. After the airborne camera captures the target image, it transmits the image information back to the ground through radio, and the image processing computer on the ground calculates the target. The information is sent back to the UAV for use by the flight control system. This type of system has no restrictions on the power, volume, and processing capabilities of ground equipment, but it will be affected by signal transmission delays; the other is the setting of the visual processing part. On UAVs, this method avoids the time delay of transmitting information through radio, and greatly improves real-time performance and reliability. However, the airborne visual processing equipment is required to be small in size, light in weight, and the power should not be too large, which limits computing processing. ability

From the perspective of visual processing algorithms, in the past, researches on visual detection and positioning at home and abroad were relatively more focused on single targets. However, the existing technology cannot perform multi-target positioning, and it is difficult to meet normal use requirements
