The invention discloses a method and device for automatic analysis, detection and treating of scene targets. Optical hardware calculation and software calculation are combined to directly face naturalscene analysis and target scene detection, and the target detection result can be effectively and quickly obtained. The method comprises the steps that (1) a Fourier system device is constructed, anda light path is built; (2) a convergent spherical mirror is adjusted to enable natural scenes to be accurately connected into a Fourier system; (3) an FPGA and an SLM are controlled to achieve spatial filtering and image collecting; and (4) scene analysis and target detection calculation are conducted. An optical link is utilized to calculate an integrated thought, the natural scenes are directlyfaced, and scene analysis and target detection can be achieved.
Description
technical field [0001] The present invention relates to the field of photoelectric imaging and computer technology, and more specifically, to a method and device for automatic analysis, detection and processing of scene objects. Background technique [0002] The analysis and detection of objects in the scene is an important part of image processing, machine vision and other fields. Traditional scene methods often post-process the image after the image acquisition is completed, analyze and detect the target in it. However, due to the introduction of inevitable noise in multiple processes such as imaging, acquisition, and processing, there are some problems in the results obtained by these methods. Some algorithms require huge prior data as support, and some methods have poor recognition results or Calculations are slower. [0003] At present, the commonly used scene target detection methods are: [0004] Object detection method based on feature detection. Segmentation and...
