An image cropping method for a single-lens 360-degree panoramic camera

Abstract

The invention discloses an image clipping method for a single-lens 360-degree panoramic camera, which comprises the following steps: step 1: first obtain the width and height of the output image of the photoreceptor; step 2: set the default screen reduction display through the obtained image width and height Step 3: Adjust the size and position of the clipping frame through the screen buttons; Step 4: Set the clipping parameters according to the adjusted image; Step 5: Cut out the image; after the image pixels are reduced in the present invention, it can be reduced year-on-year The code stream of the image, especially for panoramic devices using wireless connections, after the code stream is greatly reduced, the image fluency and real-time performance can be greatly improved, which improves the user experience.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to an image clipping method for a single-lens 360-degree panoramic camera. Background technique [0002] The image imaged by a single-lens 360-degree panoramic camera on the SENSOR is an inscribed circle. Currently, the SENSOR mainly used has two specifications, one is 16:9 (length: width), and the other is 4:3 (length: width). wide), the inscribed circle formed by the image on the SENSOR is an inscribed circle with the diameter of the smallest side of the rectangle and the center of the rectangle as the center. There are mechanical errors in the fixed position of the CUT and the tolerance between the lens and the IR-CUT. As a result, the image imaged by the lens does not have a rectangular SENSOR center position, resulting in an offset of the imaged inscribed circle image on the SENSOR, and the offset position is Random, that is, it may be left, right, upper, lower, upper right, l...

[0002] The image imaged by a single-lens 360-degree panoramic camera on the SENSOR is an inscribed circle. Currently, the SENSOR mainly used has two specifications, one is 16:9 (length: width), and the other is 4:3 (length: width). wide), the inscribed circle formed by the image on the SENSOR is an inscribed circle with the diameter of the smallest side of the rectangle and the center of the rectangle as the center. There are mechanical errors in the fixed position of the CUT and the tolerance between the lens and the IR-CUT. As a result, the image imaged by the lens does not have a rectangular SENSOR center position, resulting in an offset of the imaged inscribed circle image on the SENSOR, and the offset position is Random, that is, it may be left, right, upper, lower, upper right, lower right, upper left, lower left, etc. The back-end extracts the panoramic image by taking the inscribed circle according to the center of the image. Due to the deviation of the center position of the original image, the extracted image has problems such as black edges or blurred edges, which affects the user experience
