| titleOfInvention | Method, device and medium for calculating the actual size of a moving object based on machine vision |
| abstract | The invention discloses a method, device and medium for calculating the actual size of a moving object based on machine vision, comprising the steps of: establishing an image coordinate system on an image pixel plane, the image coordinate system including a pixel coordinate system and an image plane coordinate system; The position information and feature information of the target object in the motion state, the position information includes: the image plane coordinates of the position; two different images are selected, and the actual size of the target object in the image is calculated according to the position information and the feature information. . The invention adopts a monocular algorithm, and uses two different images at different times to calculate the target object without preset reference points. As long as there is image information, the size of the target object can be calculated, and there is no need to reset or adjust after the water area changes. The reference frame avoids the application of the binocular algorithm and saves costs. |
