specific Embodiment 1

[0087] Step 1, perform underlying configuration and initialization on the DSP.

[0088] Adopt TI TMS320C6678 DSP (hereinafter called C6678) among the present invention as system CPU, C6678 is eight nuclear processors (core 0-core 7), single-core frequency can reach 1.25GHz, can reach the processing speed of 10GHz. In the present invention, the core 7 is used as the main core for system scheduling, and is used for collecting camera data, transmitting data, connecting to a host computer for display, and the like. Core 0 is the main core for image processing, controlling and managing the remaining cores 1-6, which are used together to process data and algorithms at high speed. When starting multi-core processing, use the openmp method, so you only need to program core 0 and core 7, and add the openmp statement to the core 0 program. The initialization of DSP mainly includes clock PLL initialization, memory allocation, serial port initialization, network port initialization, indi...

Abstract

The invention relates to an unmanned aerial refueling laser visual tracking method based on a DSP, and the method comprises the following steps: initial initialization configuration of the DSP (TMS320C6678); communication and image acquisition of the DSP and a network camera; communication between the DSP and a laser sensor; implementation of quick and accurate tracking of a target on the DSP platform through the fusion of a Meanshift iterative algorithm with laser data; output of a tracking result and display through an upper computer. The method is used in the embedded vision field, and canachieve the tracking of a moving target quickly, efficiently and accurately for a high-speed unmanned aerial vehicle system. Meanwhile, the method is high in expansibility, achieves the simple connection with other modules, and gives full play to the performances of the DSP (TMS320C6678) to improve the operation speed and precision of the algorithm.

Description

technical field [0001] The invention belongs to the field of robot vision, and specifically relates to a laser vision tracking method for unmanned aerial refueling and refueling. Based on a DSP (TMS320C6678) platform, the three-dimensional coordinates of a moving target are mainly positioned using camera and laser vision technology. Background technique [0002] At present, robot vision is one of the important research fields of robot research. Most of the traditional robot vision systems are based on the PC architecture. The image processing system based on the PC architecture mainly has the advantages of strong versatility and strong scalability, but it runs the Windows operating system with complex functions, which consumes more system resources. In system services, it affects the computing performance and real-time performance of the entire system. For unmanned aerial refueling and refueling, the fast dynamic characteristics and high flight speed determine that the visi...
