Abstract

The invention discloses a dynamic adaptive linear prediction control method, system and device, and the method comprises the steps: lightening an LED light source based on a preset brightness value, and obtaining CCD imaging data; based on the CCD imaging data, obtaining the maximum light intensity value of pixel brightness in a digital analysis mode; comparing the maximum light intensity value with a preset light intensity upper limit value, adjusting a preset LED brightness value under the condition that the maximum light intensity value exceeds a preset error range, and obtaining a new maximum light intensity value after data is obtained through CCD imaging again until the maximum light intensity value and the preset light intensity upper limit value are within a preset error range; andobtaining a brightness value corresponding to the current situation as an output result. In the embodiment of the invention, the brightness of the LED light source is predicted, fed back and controlled by adopting the pixel analysis of the CCD imaging frame, so that the CCD imaging quality needs to meet the requirements of subsequent image analysis and processing.

Description

technical field [0001] The present application relates to the technical field, and in particular to a dynamic adaptive linear predictive control method, system and device. Background technique [0002] The image acquisition of the Dynamic Optical Breast Imaging (DOBI) system is an infrared light source with a wavelength of 640nm generated by the LED light source (infrared lamp array), which illuminates the breast of the human body from the bottom. After passing through the breast, the light signal is collected by a high-sensitivity CCD camera , and are recorded as approximately 30-second real-time sequences stored in digital memory. , [0003] The selection and control of the brightness of the LED light source directly affects the image quality of the CCD imaging frame. The illumination of LED infrared lights is controlled by an independent programmable microprocessor, while the CCD camera is controlled by PC software. To ensure accurate system performance, the lighting f...
