Abstract

The invention discloses a projection method and a system, relates to the field of communication, and is used for solving the technical problem that the existing projection equipment cannot prevent part of images from being projected to the face and the body of a speaker under the condition that the field is limited. The method comprises the following steps: acquiring a projection source image and a projection area image obtained by projecting the projection source image; according to a comparison result between the projection source image and the projection area image, judging whether the projection area image contains an interference object or not; and if yes, generating a mask matched with the interference object, performing mask operation processing on the projection source image according to the mask to obtain a processed projection source image, and performing projection on the processed projection source image. According to the mode, the interference object can be identified, and the projection source image is processed in a mask mode, so that the projection source image is prevented from being projected to the interference object, and the problem that the projection source image affects the interference object such as a human body is avoided.

Description

technical field [0001] The present invention relates to communication technology, in particular to a projection method and system. Background technique [0002] At present, projectors and various projection devices have become common equipment in offices and conferences. When users (speakers) use projection devices to give speeches or demonstrations, they often go to the projection area to give lectures. Correspondingly, the projection equipment will project part of the image onto the face and body of the speaker. On the one hand, it may damage the eyes of the speaker and cause inconvenience to the lecture; on the other hand, due to the influence of image projection, it will be difficult for the audience to see The facial expressions or gestures of the speaker affect the experience of users including the speaker and the audience to a certain extent. [0003] In order to solve the above problems, the solutions in the prior art are: elevating the position of the projector, or...
