Problems solved by technology

[0004] However, vision-based real-time localization and mapping (VSLAM) technology will experience tracking loss when encountering relatively few feature points such as white walls and glass.
Although the loopback detection will re-optimize the path, there will still be a large error after multiple optimizations

Abstract

The invention discloses a three-dimensional modeling method and system combined with a laser radar and a spherical curtain camera, which relates to the technical field of three-dimensional imaging modeling. The method comprises the following steps: scanning the current scene with a laser radar to obtain data in real time; triggering a spherical curtain camera to take photographs and obtain panoramic photographs; uploading radar data and panoramic photos to the mobile terminal, calculating a path and buffering the panoramic photos according to the radar data through the mobile terminal; uploading the path data and panoramic photo data processed by the step to the server for three-dimensional modeling. Laser radar real-time scanning and positioning, compared to running into a white wall, when the characteristic points such as glass and the like are few, the vision-based SLAM which is lost in tracking will appear. The real-time scanning and positioning of the laser radar is more stable and accurate than the video stream positioning of the vision-based SLAM, and the created three-dimensional model will not produce model distortion, and the scene of the created three-dimensional model is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of three-dimensional imaging modeling, in particular to a three-dimensional modeling method and system combining a laser radar and a dome camera. Background technique [0002] In the process of using a dome camera for 3D modeling, because it involves real-time positioning and mapping (SLAM) technology, the amount of data that needs to be processed for the dome camera (usually binocular or multi-purpose) to shoot video streams all the time Relatively large, this will cause a very large burden on the hardware, generate a large heating phenomenon, and the power will be exhausted in about a few minutes to ten minutes. Secondly, if you directly use the dome camera for spatial positioning, you must use the frame pictures of the video stream captured by the dome camera, and then perform SLAM positioning, but such a large amount of calculation takes up a lot of CPU resources, which will increase a huge amount of pow...
