Embodiment 1
[0032] First, refer to figure 1 An example electronic device 100 for implementing the text line detection method, device and system of the embodiments of the present invention will be described.
[0033] like figure 1 Shown is a schematic structural diagram of an electronic device. The electronic device 100 includes one or more processors 102, one or more storage devices 104, an input device 106, an output device 108, and an image acquisition device 110. These components pass through a bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structure of the electronic device 100 shown are only exemplary, not limiting, and the electronic device may also have other components and structures as required.
[0034] The processor 02 can be implemented in at least one hardware form of a digital signal processor (DSP), a field programmable gate array (FPGA), and a programmable logic array (PLA), and the processor 1...
Embodiment 2
[0041] see figure 2 A flow chart of a text line detection method is shown, the method can be executed by the electronic device provided in the foregoing embodiment, and the method specifically includes the following steps:
[0042] Step S202, acquiring an image to be detected.
[0043] In the embodiment of the present invention, the image to be detected may be an image frame in a video stream collected by a camera, or may be a picture collected by a device such as a camera. There may be a text line in the image to be detected, and the text line may be in the form of words, characters, etc., and its shape may be straight, curved or other irregular.
[0044] Step S204, acquiring attribute information of each pixel in the image to be detected.
[0045] The above attribute information includes: area attribute information, centerline attribute information, radius attribute information and slope attribute information. Among them, the area attribute information can indicate wheth...
Embodiment 3
[0078] For the text line detection method provided in Embodiment 2, the embodiment of the present invention provides a text line detection device, see Image 6 A structural block diagram of a text line detection device shown, including:
[0079] An image acquisition module 602, configured to acquire an image to be detected;
[0080] An attribute acquisition module 604, configured to acquire attribute information of each pixel in the image to be detected; the attribute information includes: area attribute information, centerline attribute information, radius attribute information and slope attribute information;
[0081] The area marking module 606 is configured to mark the area where the text line is located in the image to be detected according to the attribute information of each pixel.
[0082] The text line detection device provided by the embodiment of the present invention can determine the region attribute information, centerline attribute information, radius attribute...
