The embodiment of the invention provides an effective area parameter determination method, an image acquisition method and a test system, and the method comprises the steps: obtaining a detection image obtained by carrying out the image collection of a target area through an image collection device, and setting a positioning edge in the target area, wherein the detection image at least comprises a to-be-determined effective area of the image acquisition equipment and a positioning auxiliary area where the positioning edge is located, and the positioning auxiliary area is located at the far end of the to-be-determined effective area in the horizontal visual range of the image acquisition equipment; determining an effective area in the detection image based on the position information of the positioning auxiliary area; and performing parameter configuration on the image acquisition equipment based on the position parameter corresponding to the effective area so as to determine the effective area of the image acquired by the image acquisition equipment. According to the effective region parameter determination method, the image acquisition method and the test system provided by the embodiment of the invention, the extraction accuracy of the effective region of the image can be ensured.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method for determining effective area parameters, an image acquisition method and a test system. Background technique [0002] In recent years, with the rapid development of artificial intelligence, smart dictionary pens have gradually entered people's lives, bringing great convenience to people's work and study. The smart dictionary pen collects images of paper documents and recognizes the words in the images, for example, through Optical Character Recognition (OCR) to realize the function of looking up words. Due to the limitations of imaging and structure, there will be many invalid areas that do not contain text in the collected images. Therefore, before the smart dictionary pen recognizes the text in the image, it needs to identify the effective area that contains text in the image (Region of interest, referred to as ROI) for extraction. [0003] The existing in...
