Problems solved by technology

However, in many various application scenarios, the projector usually cannot interact with the user's behavior
[0003] Aiming at the above-mentioned defects of not being able to interact with the user's behavior, interactive projection methods such as using laser pointers to interact and using infrared laser emitters to scan and detect finger touch positions have been gradually developed. However, the interaction method of the former is still relatively monotonous, while the latter The cost is high, and the infrared laser transmitter needs to be installed close to the imaging plane, which limits the freedom of installation scenarios

Abstract

The invention provides an interactive projection system and method. The system includes a projector, a camera, and a processing unit, the projector projects projection content to an imaging plane, a projection image is formed on the imaging plane, the camera acquires the image on the imaging plane, and the processing unit is connected with the projector and the camera, identifies the interactive operation based on the image acquired by the camera, generates the projection content based on the interactive operation, and calibrates the projection content. The interactive projection system and method realize the real-time tracking interaction of the user interactive operation, and are advantageous in that the projected image does not deform, an abundant interactive manner is provided, and the application condition is not limited.

Description

technical field [0001] The present invention relates to the technical field of projection imaging, in particular to an interactive projection system and method. Background technique [0002] Projectors are currently widely used in various scenarios, including large-scale outdoor projection, video conference projection, or miniature desktop projection. However, in many various application scenarios, the projector usually cannot interact with the user's behavior. [0003] Aiming at the above-mentioned defects of not being able to interact with the user's behavior, interactive projection methods such as using laser pointers to interact and using infrared laser emitters to scan and detect finger touch positions have been gradually developed. However, the interaction method of the former is still relatively monotonous, while the latter The cost is high, and the infrared laser transmitter needs to be installed close to the imaging plane, which limits the freedom of installation s...
