Embodiment 1

[0044] Embodiment 1 of the present invention provides a city appearance environment detection method based on three-dimensional real scene data. Such as figure 1 As shown, the method includes:

[0045] Step A: Obtain lidar point cloud data and road panorama image data containing location information in urban scenes; based on lidar point cloud data and road panorama image data, the city environment can be effectively evaluated.

[0046] Step B: Fuse the lidar point cloud data containing location information and road panoramic image data acquired by the data acquisition module, and establish a one-to-one mapping relationship based on time information for the lidar point cloud data, road panoramic image data and location information; , so that the scene in the real scene image has depth information.

[0047] Step C: According to the mapping relationship, identify the feature elements to be detected in the urban scene, detect and count the feature elements, and store the detecti...

Embodiment 2

[0063] Embodiment 2 of the present invention provides a city appearance environment detection system based on three-dimensional real scene data. Such as figure 2 As shown, the system includes a data collection module 10, a data fusion module 20, a feature recognition module 30 and a database 40:

[0064] The data acquisition module 10 is used to acquire lidar point cloud data and road panorama image data including location information in urban scenes. The data collection module 40 may include a laser radar point cloud scanning device, a road panoramic image collection device and a positioning device.

Abstract

The invention relates to the technical field of feature extraction and recognition, and provides a city appearance environment detection method and system based on three-dimensional live-action data. The city appearance environment detection method includes the steps of A, obtaining laser radar point cloud data containing location information and road full view image data in city scenes, B, fusing the laser radar point cloud data containing the location information and the road full view image data which are obtained through a data acquisition module and creating a one-to-one mapping relation among the laser radar point cloud data, the road full view image data and the location information based on time information, and C, recognizing characteristic elements to be detected in the city scenes according to the mapping relation, detecting and counting the characteristic elements, and storing the detecting data and the counting data of the characteristic elements. According to the city appearance environment detection method and system based on the three-dimensional live-action data, the city appearance environment evaluation work is more efficient and objective, and meanwhile cost is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of feature extraction and recognition, in particular to a method and system for detecting a city appearance environment based on three-dimensional real scene data. 【Background technique】 [0002] Promoting the improvement of city appearance and environment is an important purpose of urban management, and the detection and objective evaluation of city appearance and environment (such as scoring road cleanliness) is the key to improving environmental quality. At present, the city appearance environment detection and evaluation is mainly carried out by manual scoring. However, the efficiency of manual scoring is low, its subjectivity is strong, and it is difficult to achieve a unified scale. At the same time, it requires a large number of administrative personnel to go to the scene and will generate large administrative costs. [0003] In view of this, it is an urgent problem to be solved in this technical f...
