Abstract: A three-dimensional scene constructing method, apparatus and system, and a storage medium. The three-dimensional scene constructing method includes: acquiring point cloud data of a key object and a background object in a target scene, wherein the point cloud data of the key object comprises three-dimensional information and corresponding feature information, and the point cloud data of the background object at least comprises three-dimensional information; establishing a feature database of the target scene, wherein the feature database at least comprises a key object feature library for recording three-dimensional information and feature information of the key object; performing registration and fusion on the point cloud data of the key object and the point cloud data of the background object, so as to obtain a three-dimensional model of the target scene; and when updating the three-dimensional model, reconstructing the three-dimensional model in a regional manner according to the feature database.

Abstract: A meter monitoring system (200) includes: a wireless gateway (202), a monitoring device (201), and at least one meter recognition apparatus (100). The meter recognition apparatus (100) includes: an image acquirer (1), a processor (2), and a wireless transceiver (3). The image acquirer (1) is configured to acquire images of a display side of a monitoring meter (4) at set time intervals. The processor (2) is coupled to the image acquirer (1) and configured to determine, according to an image of the images acquired by the image acquirer (1) and based on an image processing algorithm, monitoring data displayed by the monitoring meter (4). The wireless transceiver (3) is coupled to the processor (2) and configured to send the monitoring data determined by the processor (2) to the wireless gateway (202). The wireless gateway (202) is configured to transmit the received monitoring data to the monitoring device (201).
