Image data acquisition method for intelligent interactive micro-projection device

Abstract

The invention provides an image data acquisition method for an intelligent interactive micro-projection device. An acquisition system used by the image data acquisition method comprises a main control unit, a micro-projection unit and an image acquisition unit, wherein the main control unit is electrically connected with the micro-projection unit and the image acquisition unit. The image data acquisition method comprises the following steps that micro-projection image data transmission is started; when micro-projection image data transmission is conducted, the main control unit detects whether a high-level field synchronizing signal is input by an input signal end or not, and if the high-level field synchronizing signal is input by the input signal end, the main control unit generates a trigger signal at an output signal end according to the exposure demand, and transmits the trigger signal to a controllable exposure pin of the image acquisition unit; the image acquisition unit accomplishes controllable exposure in a window period of projection, and acquires image data; the image acquisition unit transmits the acquired image data to the main control unit. The image data acquisition method is low in cost and wide in application range, and color images can be acquired; compared with gray level images of an existing intelligent interactive device, acquired images are richer in content, and image data processing can be more flexible.

Description

technical field [0001] The invention relates to the technical field of image data processing, in particular to an image data collection method for an intelligent interactive micro-projection device. Background technique [0002] At present, products related to micro-projection are developing rapidly, and the combination of projection technology and intelligent human-computer interaction will be the innovative direction of projection equipment in the future. [0003] In order to eliminate the impact of the projection light generated by the intelligent interactive projection equipment on the interactive image processing algorithm, the existing intelligent interactive projection equipment uses near-infrared image acquisition technology, and the projected content is invisible in the collected image information. of. [0004] The image acquisition method adopted by the existing intelligent interactive projection equipment has at least the following problems: the existing technolo...
