the deviation detection mechanism is connected with the contour recognition mechanism and is used for acquiring each brightness value of each pixel forming the target image area, performing mean square deviation calculation on each brightness value and sending a bleaching deviation instruction when the obtained mean square deviation value is larger than or equal to a preset mean square deviation threshold value;
and the deviation detection mechanism is also used for sending out a bleaching uniformity instruction when the obtained mean square error value is smaller than the preset mean square error threshold value.
5. The real-time wood bleaching deviation detection platform of claim 4, wherein the platform further comprises:
the voice playing chip is arranged on the integrated circuit board where the cloth control shooting mechanism is arranged and connected with the deviation detection mechanism;
when the voice playing chip receives the bleaching deviation instruction, a voice prompt file corresponding to the bleaching deviation instruction is played;
and when the voice playing chip receives the bleaching uniformity instruction, playing a voice prompt file corresponding to the bleaching uniformity instruction.
6. The real-time wood bleaching deviation detection platform of claim 5, wherein:
searching for one or more matching image regions from the three-stage processing picture based on the processed contour shape of the sprayed wooden board includes: and taking an image area, of the three-level processing picture, with the matching degree of the processed outline shape of the sprayed wood board exceeding a preset proportion threshold value as a matching image area.
7. The real-time wood bleaching deviation detection platform of claim 6, wherein:
outputting the matching image region with the largest area in the more than one matching image regions as the target image region comprises: and acquiring the number of pixels occupied by each matching image area, and outputting the matching image area occupying the largest number of pixels as a target image area.
8. The real-time wood bleaching deviation detection platform of claim 7, wherein:
the second spraying mechanism is also used for sending a standby waiting instruction when the second preset time length is not reached after the cold water spray-washing operation is finished;
and the control shooting mechanism is also used for not executing shooting operation on the sprayed wood board when receiving the standby waiting instruction.
9. The real-time wood bleaching deviation detection platform of claim 8, wherein:
the cold water flushing instruction sending method comprises the following steps that when the first spraying mechanism finishes spraying for a first preset time length, the cold water flushing instruction sending step comprises the following steps: the cold water flushing device is used for sending out a cold water flushing instruction when the first spraying mechanism finishes spraying for 20 minutes;
wherein, still be used for reaching the second after accomplishing cold water spray rinsing operation and predetermine the duration, send and detect trigger command and include: and the device is also used for sending a detection trigger instruction when the time reaches 30 minutes after the cold water spray operation is finished.
10. A method for real-time detection of wood bleaching bias, the method comprising using a real-time detection platform of wood bleaching bias according to any one of claims 4-9 to detect wood bleaching bias in real time based on a targeted wood bleaching mechanism to achieve effective evaluation of wood bleaching effect.
