Problems solved by technology

There is still a usability problem in the traditional camera calibration method. Currently, the more popular methods often require manual interaction to complete.
The high degree of manual interaction makes the repeatability of traditional calibration methods low, and manual steps need to be repeated once for calibration

Abstract

The invention relates to the field of image processing, and discloses a vehicle-mounted-based automatic calibration control method. The method comprises the steps of obtaining video image data, identifying the number of calibration points, and obtaining positioning data of vehicle-mounted positioning points; acquiring positioning data of a first calibration position at the first calibration distance; acquiring positioning data of a second calibration position at a second calibration distance; calculating the course of the vehicle body according to the positioning data of the first calibrationposition and the second calibration position; calculating an included angle between the vehicle body heading and a connecting line of the first calibration point and the second calibration point; andtriggering calibration when the absolute value of the included angle-90 degrees is smaller than or equal to a first threshold value. The invention further discloses a corresponding storage medium andsystem. Some technical effects of the invention are that automatic control of camera calibration is realized.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an automatic calibration control method in the field of image processing. Background technique [0002] Vision is an important means for humans to observe and understand the world, accounting for 70% of the information humans obtain from the external environment. Human beings use their eyes to obtain the light reflected by surrounding objects or emitted by themselves. The light forms an image on the retina and is transmitted to the brain through nerve fibers. The brain processes and understands the visual information and finally forms vision. Computer vision simulates the function of human vision, uses cameras to obtain images of the surrounding environment, and uses computers to process images. Computer vision can accomplish tasks that human vision is not capable of, such as accurate measurement of the size and distance of the object to be measured. Computer vision technology c...
