Problems solved by technology
Among them, identifying the target by altitude is also an important identification method, but in the prior art, when identifying the target by altitude, the scene is required to be fixed, and the altitude needs to be calibrated manually. In the case of many samples that need to be excluded, this This method greatly increases the workload of the staff, and there is a high probability of error

The invention relates to the technical field of target recognition. The invention particularly relates to a height detection method and device, a height detection equation establishment method and device and terminal equipment. The height detection method comprises the following steps: identifying a target in a picture shot by a camera, and obtaining the pixel height of the target object and the coordinate value of the target object in a predefined two-dimensional coordinate system, and finally substituting the coordinate value and the pixel height into a height detection equation establishedby a height detection equation establishment method to calculate the height of the target object. According to the scheme, the pixel height and the coordinate value of the target object are collectedand then substituted into the pre-established height detection equation to calculate the height of the target object, the whole calculation process is simple and efficient, the working efficiency is improved, and workers are prevented from repeatedly carrying out manual calibration.
Description
technical field [0001] The invention relates to the technical field of target recognition, in particular, to a height detection method and a method for establishing a height detection equation. Background technique [0002] There are a variety of methods for identifying targets in the prior art, and the technology for identifying targets can be widely used in a variety of fields, such as helping the public security solve a case, identifying the target person to quickly help the police find suspicious people, and can also be applied to Lost and found, such as identifying suspicious items within a certain range of scenes, helping the owner find the lost item as soon as possible. The identification of the target is mainly by extracting more information from the target, and by comprehensively analyzing various information to determine the target. Among them, the recognition of the target by height is also an important recognition method, but when the target is recognized by the...
