Image analysis system and image analysis method

The invention discloses an image analysis system and an image analysis method. The image analysis system comprises an image acquisition device and a processor; the image acquisition device is used for acquiring an image to be analyzed; and the processor is used for inputting the to-be-analyzed image to a regional convolutional neural network model, the regional convolutional neural network model outputs a mask image, the processor calculates a center of a mask object in the mask image, the center is regarded as a coordinate origin, a farthest coordinate point farthest from the origin of coordinates in four quadrants relative to the origin of coordinates is searched, an image analysis block for each farthest coordinate point is generated, and post-processing is performed on the image analysis blocks to obtain an object range. 一种影像分析系统及影像分析方法，所述影像分析系统包含：一影像获取装置以及一处理器；影像获取装置用以获取一待分析影像；处理器用以将待分析影像输入至一区域卷积神经网络模型，区域卷积神经网络模型输出一遮罩影像，处理器计算遮罩影像中的一遮罩物件的一中心，将中心视为一坐标原点，往相对坐标原点的四个象限分别搜寻与坐标原点距离最远的一最远坐标点，对于每个最远坐标点产生一影像分析区块，并
