Abstract
An image information processing method includes obtaining, by an AR device, a first image including an image of a target object. The method includes detecting an environmental parameter of the AR device based on the first image. The method includes determining a cropping ratio coefficient of the first image based on the environmental parameter. The method includes cropping the first image based on the cropping ratio coefficient, to obtain a second image. The method includes extracting M contour feature points in a remaining image of the target object from the second image, to generate an AR image of the target object. The method includes displaying the AR image on a front windshield of a car.
