Description of the invention (2) Manual counting method ; After all the fish fry collections are collected and distributed to many collectors, one of them is taken to count the number of fry, and multiplied by the number of collected slugs to estimate the total number of forged fry. Shrimp fry are limited to visual ability. Only 5 to 5 to 6 fish can be taken out at a time, and the counts are added up one at a time. However, the forged fry in each collector ranges from 10,000 to 20,000. The counting work is quite time-consuming, and the counting result depends entirely on the lotus (because only one collection tube is sampled for counting) and the conscience of the person who performed the counting work, so it lacks fairness and it is difficult to establish a fair trading principle, and Working in this industry, Bei Bei presents 10 aging human resources, and there is a risk that the counting work could not be passed down. Because the penguin fry has swimming habits and overlap, it is difficult to master the counting work, so there is no good counting method to replace manual counting. The present invention applies a machine vision system to image the image processing method of sturgeon fry, in order to provide a more accurate and convenient penn fry count system. 15 The present invention discusses an image processing method for accurately counting net fry fry counts. To improve the accuracy of forging fry fry counts, erosion and expansion lotus arithmetic are used in the mathematical morphology of Binary. (Dilation) is used alternately, which can separate the heavy fry fry, or trim the shape of the peng fry to smooth it, so that it can be accurately counted in the last 20. The present invention focuses on the feasibility counting method of image processing with high reliability, accuracy and stability, and M cooperates with the forage fry distribution mechanism to develop a visual system for penguin fry counting that can be used on site. The main purpose of the present invention is to discuss the image processing method, in conjunction with the binary form --------- ¢-(please first read the note $ item on the back and then #write the book to buy>

Description of the invention (4) Kailian is a lotus calculation that is eroded first and then swollen gland, and closed calculation is a calculation that swells first and then erodes. Using a round structure to open the lotus can smooth edges, interrupt narrow bridges, and eliminate small islands and sharp points in shape. With closed lotus roots, you can smooth edges, box cracks and slender pits, fill small holes and 5 gaps in the edges. The process of the test of the present invention is to take the image of the bristlefish fry and give it a binary image, and when the tuna fry are separated from each other in the shape of the burr, some fine points must be modified into a smooth, elegant, and A single forged fry is divided into incomplete thieves and must be reconnected as a whole. In addition, when the forged fry is heavy, it must be separated as much as possible. In order to overcome these problems, the present invention uses an effective binary morphological erosion operation and expansion. The calculation is used alternately, and the mine counting work is performed. (3) Image counting method t The present invention uses the embroidery length method 15 (Run length) to process according to the number of objects fit and area of the object. The number of individuals is counted and the area of each individual is recorded at the same time as the number of juveniles. Basis of overlap. [Inspection Results] The present invention accurately counts the number of shrimp and fry by using the image processing method of the machine vision system. The first picture is the original image of the fry after being taken. The following 20 describes each processing step and its results one by one: (1) The effect of binarization. The second is a binary image obtained by calculating the threshold. The result is quite satisfactory. It can be seen from the illustration that the snorkeling fish becomes smaller after binarization. Therefore, after binarization, the planktonic fish is larger and the snorkeling fish is smaller. ---------_ ^-(read first f read the note f on the back and then the nest)

Description of the invention (5)-(2) Form processing Methods and results It can be seen from the observation of the binary circle image in Yuan Shuo Er that the overlapping fry can be separated by using the morphological erosion lotus calculation. _The third is the result of the etching operation of Figure Two. From the results of the first three, some overlapping fish fry can be successfully separated after the 5 immersion operation. In addition, the result of the etching is again subjected to the expansion operation, that is, the imitation operation is performed, and an image such as Yuan said is obtained, and the result looks ideal. However, it was found that after the four-line open operation, some fry were originally separated into small branches from the whole ship, but they were not connected to a complete 10 stages by the expansion process in the open lotus calculation. The closed operation can overcome this problem, as shown in Figure 5, and the reason why the area calculation criterion can be used is that the closed operation is first expanded / contracted. Therefore, the fry has been released into a small ship. Once again, the utility is integrated, so the accuracy of counting can be improved by the operation of opening and closing. (3) Counting method and result ’15 The morphologically processed image depends on area calculation or point calculation. M counts the number of fry, and the accuracy rate is over 98%. Compared with manual counting, the counting speed is ten or even dozens of times higher than the manual counting. It is slightly different due to the size of the fish. The smaller the fish, the higher its counting ability. Regarding the mechanism part of the present invention, the explanation is as follows: Please refer to the first, second, and third figures, which are schematic diagrams of the disc type mechanism of the present invention. It is arranged on a platform 1 with a plurality of bowls 11 evenly distributed in a circular manner. The bowls 11 are driven by a motor 12 to rotate around an axis 13. A visual machine 2 is arranged above the bowls 11 and controlled by a computer 3 , M output control (Please read the precautions on the back before filling in Ji)
