Example Embodiment
[0032] Example 1: Real-time detection of fruit raw materials and foreign body removal system based on machine vision
[0033] As shown in Figure 1, a machine vision-based real-time detection and foreign body removal system for fruit materials includes a conveying device, a power subsystem, an optical lighting subsystem, an image acquisition subsystem, an image recognition and motion control subsystem, and a foreign body removal subsystem And accessories.
[0034] The conveying device includes a transmission belt 5, a roller, a power system, an elastic coupling 7 and a rotary encoder 8. The transmission belt 5 is a transparent transmission belt. The two ends respectively surround one of the driven rollers 9 and the second of the driven rollers 10. The transparent transmission belt used not only meets the requirements of food hygiene, but also can transmit light to obtain the tested fruit The image at the bottom of the raw material can greatly improve the detection efficiency and ac...

[0048] Example 2: Real-time detection and defect removal system for hemispherical objects based on machine vision
[0049] A real-time detection and defect removal system for hemispheres based on machine vision differs from the system described in Embodiment 1 in the following points:
[0050] 1. The optical lighting system is composed of a dome light source illuminated on the top surface, a backlight or an LED light box illuminated on the front;
[0051] 2. The system uses cameras arranged in the upper and lower positions and in the circumferential direction to obtain the full-area image of the hemisphere. As shown in Fig. 6, three area scan cameras 3 in the circumferential direction are separated by 120° from each other and are installed at the same level of the conveyor belt. The through-beam fiber optic sensors 4 are symmetrically arranged on the sensor brackets on both sides of the conveyor belt 5; The hemisphere 17 is transported in a single row, so only one set of rejection...
