Object counting system and object counting method

An object counting system based on an image, comprising:

• a processor;
• and
• a storage device, wherein the processor is configured to access the programs stored in the storage device to implement an image-cutting module, an image-object detection module, a stitching module and a result-analysis module, wherein:
• the image-cutting module is configured to receive an image and to cut the image into a plurality of split images;
• the image-object detection module is configured to input the split images into a neural network to identify an object from the split images;
• the stitching module is configured to merge a first split image of the split images and a second split image of the split images into a merged image in response to a distance between at least one side of a bounding box being associated with a position of the first object in the first split image and at least one side of a bounding box being associated with a position of the second object in the second split image adjacent to the first split image is less than a tolerance value, so that the first object and the second object are merged into a merged object, and a position of the merged object is remarked;
• and
• the result-analysis module is configured to calculate a prediction number of the object according to the object in the split images and the merged object in the merged image included in the split images;
• wherein the result-analysis module calculates the prediction number of the object by:
• subtracting a number of the merged object in the merged image from a number of the object in the split images.
