Problems solved by technology
[0003] However, when acquiring the volume of a spatial target in a video, there are often the following technical problems: the existing technology cannot measure the height of the target on the video, and the height line drawn on the video can only be calculated according to the distance, without considering its space Factors such as projection, because the video picture has spatial stereoscopic properties and picture distortion properties, the height is not equal to the length, there is a difference, and the length value is used to represent the height, and the resulting target volume often has a large error

The embodiment of the invention discloses a method and a device for carrying out stereo measurement on a video picture, and terminal equipment. According to one specific embodiment, the method comprises the steps of obtaining a to-be-processed target image, wherein the target image is a camera video picture; obtaining a target pixel point coordinate set determined by a user, wherein the target pixel point coordinate set comprises a target bottom contour pixel point coordinate set, target vertex coordinates and target bottom center point coordinates; determining a physical height based on the target vertex coordinate and the target bottom center point coordinate; determining a target sectional area based on the target bottom contour pixel point coordinate set; determining the product of the physical height and the target sectional area as a target volume; and sending the target volume to the target terminal device for signal output. According to the method, the volume of the object corresponding to the target pixel point coordinate set is directly measured in the video picture in the camera, space correction processing is avoided, the processing flow is simplified, and the accuracy of signal output is improved.
Description
technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a method, device, and terminal device for performing stereo measurement on a video screen. Background technique [0002] Spatial measurement and calculation refers to the measurement and analysis of the basic parameters of various spatial objects in geographic information systems, such as the location, distance, perimeter, area, volume, curvature, spatial form, and spatial distribution of spatial objects. Spatial measurement and calculation are the basic means of obtaining geospatial information in GIS, and the obtained basic spatial parameters are the basis for complex spatial analysis, simulation and decision making. In the prior art, it only involves distance measurement and area measurement operations in a two-dimensional map model, and height measurement operations in a three-dimensional map model. There is no direct operation of height measureme...
