The invention provides an image recognition system and an image recognition method. The image recognition system comprises an image sensor and an image processor. The image sensor obtains a plurality of sensing images of continuous frames. The image processor performs image recognition on the plurality of sensing images. The image processor respectively determines whether the plurality of sensing images are valid frames not including the road so as to determine a plurality of valid sensing images. The image processor judges whether the proportion of the area of the drivable area in the sub-image areas of each of the effective sensing images is smaller than a preset proportion or not so as to carry out danger marking. The image processor respectively calculates a plurality of danger mark numbers of a plurality of sub-image areas of the plurality of effective sensing images. When the number of the danger marks is higher than a preset threshold value, the image processor generates a danger prompt. Therefore, whether the drivable area of the current driving environment is too low or not can be effectively and automatically identified, and a danger prompt can be automatically generated.
本发明提出一种影像辨识系统以及影像辨识方法。影像辨识系统包括影像感测器及影像处理器。影像感测器取得连续帧的多个感测影像。影像处理器对多个感测影像进行影像辨识。影像处理器分别判断多个感测影像是否为未包括道路的有效帧,以决定多个有效感测影像。影像处理器分别判断多个有效感测影像的每一个的多个子影像区域中的可行驶区域的面积的占比是否小于预设占比,以进行危险标记。影像处理器分别计算多个有效感测影像的多个子影像区域的多个危险标记数量。当危险标记数量高于预设阈值时,影像处理器产生危险提示。由此,可有效且自动地辨识当前行车环境的可行驶区域是否过低,并可自动地产生危险提示。
