Problems solved by technology

These solutions implemented on general-purpose devices have high requirements on image quality and device hardware configuration in order to obtain good recognition results, which are costly and difficult to maintain.
For remote devices that need to respond quickly, these solutions implemented on local general-purpose devices will cause delays due to transmission, and the efficiency of video capture and storage is also low

Embodiment Construction

[0051] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0052] An embedded device for image capture and rapid target recognition (hereinafter referred to as "embedded device") is a device applied to video collection, image capture, target recognition, and output response signals. Embedded devices can capture video signals and digital image signals. After the signal capture process is over, the embedded device can preprocess the input signal using different processing methods such as encoding, decoding, compression, and synchronization according to the requirements of the identification and response system. After the preprocessing is completed, the digital signal is input into the recognition response system, and the system performs feature extraction and target recognition operations. After obtaining the target information, output the response signal to other coupled devices. For example, embedded ...

Abstract

The invention provides a method for catching images and quickly recognizing targets and an embedded device. The embedded device comprises an input port used for receiving video signals and a recognition reaction system used for catching the images and quickly recognizing the targets. The input port comprises a video collection port and a digital image input port. The recognition reaction system comprises a preprocessing module and a recognizing module. The embedded device can be applied to the fields of intelligent homes, unmanned detection and the like, the purposes that the targets in the images or the videos can be quickly recognized during unmanned monitoring and reaction signals are sent out according to the external device requirements are achieved, the embedded device transplants target recognition operation to an embedded environment from a computer, the transmission loss is reduced, and meanwhile the embedded device only having a data collection function can be more intelligent.

Description

technical field [0001] The invention belongs to the field of embedded technology and target identification technology, and in particular relates to a method and embedded device for image capture and target rapid identification. Background technique [0002] In the field of intelligent hardware and unmanned detection, it is becoming more and more important to quickly capture useful images and detect targets in the images, and then quickly identify and respond quickly according to user settings. Although target recognition technology, especially face recognition, pedestrian target recognition technology, and vehicle target recognition technology, has been gradually applied, most of these technologies are applied to general-purpose devices such as personal computers, servers, and workstations in the actual commercialization process. These solutions implemented on general-purpose devices have high requirements on image quality and device hardware configuration in order to obtain...
