Embodiment Construction

[0023] A specific embodiment of the present invention is the vision system of an autonomous mobile robot, that is, as the "eyes" of the robot, it searches, recognizes, and extracts the target to be recognized within the field of view, marks the position of the recognized target in the field of view and passes Display cell output. At the same time, the vision system transmits the position parameters of the target in the field of view to the robot's power system through the external interface, which determines the direction of travel and drives the entire system.

[0024] Fig. 1 depicts a system block diagram according to a specific embodiment of the present invention. The power supply unit is connected to other units to provide the voltage necessary for the work of each component unit of the system. The acquisition unit in the imaging subsystem collects the image information of the target to be identified, converts it into a digital signal through A / D, sends it to the main pro...

Abstract

A rapid target-identification and positioning system and a method relate to DSP and CPLD, FPGA technologies, as well as to image processing and mode recognition technologies. The system comprises a power unit, an imaging subsystem, a main processor, a memory subsystem, a control subsystem and an external interface circuit. The system is characterized in that being the calculating core of the whole system, the main processor is connected with all subsystems; and the imaging subsystem and the memory subsystem are respectively connected with the control subsystem; the digital signal collected, converted and input by the collecting unit of the image subsystem is submitted into the main processor and displayed by the display unit of the image subsystem after being processed; the power unit which is connected with the imaging subsystem, the main processor, the memory subsystem and the control subsystem can be used for supplying working voltage for collecting, displaying and processing signal and for the control of processing; the system has simple structure, high complexity, small size, high processing speed, and high identification rate.

Description

technical field [0001] The present invention relates to DSP (Digital Signal Processor, digital signal processor) and CPLD (Complex Programmable Logic Device, complex programmable logic device), FPGA (Field Programmable GateArray, Field Programmable Gate Array) technology and image processing, pattern recognition technology, especially A system and method for target recognition and positioning are provided, which are used to identify and extract specific targets in complex backgrounds. Background technique [0002] With the advancement of science and technology, pattern recognition and computer vision technology have made great progress, and the technology of using visual information to identify and locate targets is also constantly improving. As early as the 1970s, the target positioning technology in pattern recognition has been widely used in crop yield estimation, resource exploration, weather forecasting and military reconnaissance. With the development of economy, coun...
