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 present invention relates to the technical field of target recognition, in particular to a method and device for height detection, a method and device for establishing a height detection equation, and a terminal device, wherein the height detection method includes identifying a target in a picture captured by a camera, and obtaining the target The pixel height of the object and the coordinate value of the target object in the predefined two-dimensional coordinate system, and finally substitute the coordinate value and the pixel height into the height detection equation established by the establishment method of the height detection equation to calculate the height of the target object high. In this solution, the height of the target object is calculated by collecting the pixel height and coordinate value of the target object, and then substituting it into the pre-established height detection equation to calculate the height of the target object. The whole calculation process is simple and efficient, which improves work efficiency and avoids repetition Perform 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 many methods for identifying targets in the prior art, and the technology for target identification can be widely used in various fields, such as helping the police solve crimes, quickly helping the police find suspicious persons by identifying target persons, and can also be applied to Lost and found, such as identifying suspicious items in a certain range of scenes, helping the owner find the lost item as soon as possible. Identifying the target is mainly to extract more information from the target, and to determine the target through comprehensive analysis of various information. 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 i...
