The invention discloses a high-voltage electric wire ranging system and method based on FPGA hardware and binocular vision. The system comprises a binocular camera and a FPGA data processing module connected to the binocular camera, wherein the FPGA data processing module comprises an image data acquiring unit, an image pre-processing unit, a three-dimensional matching unit and a three-dimensional modeling unit. The high-voltage electric wire ranging system collects an original image pair of a high-voltage electric wire in a some same scene in real time by using the binocular camera, so that the high-voltage electric wire ranging system can be applied to a high-voltage operation occasion in real time; by virtue of a visualized characteristic of image information, pre-processing, three-dimensional matching and three-dimensional modeling processing on the image are performed by using the FPGA data processing module; and the processing course is high in speed to obtain depth information of the high-voltage electric wire so as to further obtain the distance of the high-voltage electric wire. The ranging result is accurate, and the system is high in definition, small in size and simple in structure and can be used for multi-occasion real-time measurement.

Description

technical field [0001] The invention relates to the technical field of high-voltage safety, in particular to a high-voltage wire ranging system and method based on FPGA hardware and binocular vision. Background technique [0002] Binocular stereo vision distance measurement is a passive distance measurement method, which imitates a distance measurement method that humans use binocular perception of distance. It mainly uses two cameras to image the same object in the same scene at different imaging positions of the two cameras to obtain corresponding parallax, and determines the depth information of a specific target object according to its parallax and baseline. [0003] In the field of high-voltage safety technology, the higher the voltage level of high-voltage wires, the greater the required safe working distance. The workplaces of high-voltage workers are complex, and the risk of accidental high-voltage electric shock accidents is extremely high. Therefore, accurate meas...
