[0074] In order to more clearly elaborate the technical solution of the present utility model, the following details the specific working principle of this application in combination with the above - mentioned structure:

[0075] This bracket adopts an integrated design and can simultaneously fix multiple cameras and lidars with different functions on the same platform. This design reduces the dispersion of devices, improves the space utilization rate, and simplifies the wiring and connection process.

[0076] The main mounting bracket is provided with multiple mounting points in the form of oblong holes, and each mounting point is equipped with a threaded hole for fixing the camera mounting bracket.

Users can adjust the pitch angle and yaw angle of the camera according to the actual shooting requirements. This design can meet the shooting requirements in different application scenarios and improve the adaptability of the system.

[0079] The integrated cameras may include various types such as imaging cameras, environment perception cameras, etc. They can capture image information from different angles and field of views, providing rich environmental data for the system. The lidar measures information such as the distance, azimuth, and speed of the target by emitting laser pulses and receiving reflected signals, realizing the precise perception and modeling of the surrounding environment.

[0080] The cameras and lidar work together under the integration of the bracket, jointly providing the system with all-round and multi-angle environmental perception and data acquisition capabilities, supporting applications in fields such as autonomous driving, UAV navigation, and robot vision.

[0081] By integrating cameras and lidar with various different functions, this bracket can achieve all-round perception of the surrounding environment. The cameras are responsible for collecting image data, while the lidar is responsible for measuring information such as distance and speed. The collected data will be synchronously and fusion-processed through a preset communication protocol. This processing can ensure that the data collected by different devices is consistent in time and space, providing accurate and reliable information support for subsequent data analysis and decision-making.

The overall design takes into account the requirements of easy maintenance, such as convenient disassembly and replacement of devices such as cameras and lidar, as well as easy cleaning and maintenance, etc.

[0086] Another object of the present utility model is to provide an autonomous vehicle, and this transport vehicle applies the above-mentioned top-level integrated bracket, and a plurality of different cameras or radars can be integrally mounted on the top-level integrated bracket.
