Abstract

The invention relates to the image processing field, in particular to a projection method and device. The projection method and device are used for solving the problem that in the prior art, due to the fact that a picture to be displayed is easily blocked by an object, use of the projection system is influenced. According to the projection method and device, after an object is detected to exist in the projection area of the projection device, the object image area, located in a projection image, of the object is determined according to the position where the object is located, the blank image area in the projection image is then determined according to the object image area, and finally an image to be displayed is regulated according to the blank image area and the regulated image to be displayed is projected so that the image to be displayed can be projected to the blank projection area in a projection picture. By means of the method, a picture formed by projecting the image to be displayed can be automatically regulated to the blank position on a projection plane, and therefore the problem that use of the projection system is influenced due to the fact that the picture to be displayed is easily blocked by the object is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a projection method and device. Background technique [0002] Image projection is to use digital light processing technology to project images onto a projection plane, so that users can see images on the projection surface, and can adjust the size, color, clarity, etc. of the images that users see. [0003] In the current catering industry, some restaurants or coffee bars have applied some interactive projection systems in order to facilitate customers to order food. This kind of projection system can project the image of the ordering interface onto the desktop, allowing the user to operate according to the picture projected on the desktop. Since there will be many tableware, food and other objects on the table during the meal, and the projection screen of the projection device is generally fixedly projected on a certain area on the table, so the screen that needs to be d...
