Embodiment 1

[0024] Due to the need to fuse the data obtained by the panoramic camera and the lidar module, the position of the dynamic target in the three-dimensional space changes at different times. fusion. In order to solve this technical problem, this embodiment proposes a device for three-dimensional information mapping, such as figure 1 As shown, the device includes a GPS timing board, a panoramic camera, a lidar module, an inertial navigation data module, a mobile equipment terminal, a storage module and a data processing module; the time synchronization control signal output end of the GPS timing board It is connected with the time synchronization control signal input end of the panoramic camera, the lidar module and the inertial navigation data module; the radar signal input end and the inertial navigation data signal input end of the panoramic camera are respectively connected with the lidar module and the inertial navigation data signal input end. The signal terminals of the m...

Embodiment 2

[0036] The solution of this embodiment is a further limitation to the device proposed in Embodiment 1, such as image 3 As shown, since the storage module needs to store 8K video acquisition data, lidar data, and inertial navigation data, the required storage speed is very high. The module and the inertial navigation data module respectively perform data transmission with the storage module through different threads.

[0037] Wherein, the storage module controls the data storage operation on different threads corresponding to the panoramic camera, the laser radar module and the inertial navigation data module through a mutually exclusive control manner.

[0038] The storage module includes a cache module, a data compression module and a memory; the data signal input end of the cache module is the storage data input end of the storage module; the data output end of the cache module is the same as the data compression module. The data signal input end is connected; the data sig...

Description

technical field [0001] The invention provides a device for three-dimensional information surveying and mapping, which belongs to the technical field of surveying and mapping. Background technique [0002] The surveying and mapping device is an indispensable equipment in the surveying and mapping work. The surveying and mapping device specifically refers to the data collection, processing, output and other instruments and devices designed and manufactured for the surveying and mapping operation. Various instruments for orientation, ranging, angle measurement, altimetry, mapping and photogrammetry required for surveying work in the planning and design, construction and management stages of engineering construction. However, the existing three-dimensional information surveying and mapping devices often cause problems of low precision and accuracy of the acquired three-dimensional spatial information due to the poor uniform accuracy of the acquisition time of the data acquisitio...
