Description

technical field [0001] The invention relates to a multi-sensor synchronous control device for an air-based road surface information detection platform, which is especially suitable for synchronous control of various equipment and sensors carried by the air-based road surface information detection platform, and belongs to the field of air-based road surface information detection. Background technique [0002] With the rapid development of my country's road traffic network, the demand for road information detection is increasing day by day, and the air-based road surface information detection platform has been widely valued due to its advantages of non-contact and good mobility. The fixed-wing aircraft used in traditional aerial photography and surveying and mapping has a high flying altitude (3000m), while the rotorcraft has defects such as short flight range and low efficiency; Space-based road surface information detection platform for fixed-wing unmanned aerial vehicles. ...

AI Technical Summary

Problems solved by technology

[0003] The SLR cameras, photoelectric pods, and laser radars integrated in the platform are independent of each other and have different startup methods, so they cannot be started at the same time

Individual devices start to work after power-on, consume electricity and have invalid data, occupy limited storage space, waste limited on-board resources, increase costs, reduce efficiency, and cause inconvenience to later data processing work

Although SLR cameras, photoelectric pods, and laser radars all have storage functions, due to the different acquisition rates and storage formats of each sensor, it is impossible to establish a unified mark, which is not conducive to the multi-dimensional comparison of data.
