Embodiment Construction

[0037] The technical scheme that the present invention implements is as follows:

[0038] 1. The image data adopts the common output format of the image sensor, that is, the frame synchronization signal, the line synchronization signal, the binary image data and the pixel synchronization clock are used as the image input signal.

[0039] 2. Effective period of the first line: Detect the run-length information of the first line of images, and store the run-length information into the on-chip storage space.

[0040]3. The valid period of the second line: Detect the run-length information of the second line of images, and store the information in the on-chip storage space; convert the run-length information of the first line into the connected area information and write it into the corresponding connected area information storage space; A run-length look-up table of one row, the run-length look-up table records the run-length information and the merging relationship between the r...

Abstract

The invention provides an FPGA-based binary image connected region information fast acquisition system and a method. The method comprises the steps of adopting a frame synchronization signal, a line synchronization signal, binary image data and a pixel synchronization clock as an image input signal; detecting the run-length information of a first row of images during a first row validity duration; detecting the run-length information of a second row of images during a second row validity duration; merging the first row of the run-length information to obtain the information of a communicated region; establishing a first row run-length look-up table; detecting the run-length information of the second row of images during a third row validity duration; merging the second row of the run-length information based on the first row run-length look-up table to obtain the information of the communicated region; and establishing a second row run-length look-up table. The subsequent operation is consistent with the operation on the third row. After images are already input, the information of the communicated region can be obtained. According to the technical scheme of the invention, the pipeline operation is conducted and the parallel advantages of the FPGA are fully utilized. Meanwhile, the information of the communicated region of high-resolution images can be obtained in real time.

Description

【Technical field】 [0001] The invention provides a method for image recognition and target information extraction, in particular to an FPGA-based system and method for quickly acquiring information of a connected area of ​​a binary image. 【Background technique】 [0002] A binary image refers to an image in which each pixel is represented by "0" or "1". The connected region labeling algorithm requires that all the pixels belonging to the same connected region in the binary image are marked with unique labels, and the information such as the area of ​​the connected region and the circumscribed rectangle is counted at the same time. This process is a very important basic operation in computer vision, pattern recognition and image tracking, and has a wide range of applications. [0003] The connected area labeling is divided into two statistical results based on 4-neighborhood and 8-neighborhood. The 4-neighborhood refers to the image area composed of the target pixel and four p...
