Abstract

The invention discloses an object image detection method and an object image detection device capable of improving the classification performance. According to the object image detection method capable of improving the classification performance, an embedded system acquires image information, detects the image information to generate a circle-selection range of an obstacle as the initial contour of the obstacle, generates a correct contour of the obstacle by a Poisson vector active deformation contour algorithm based on the circle-selection range, using a multi-grid algorithm and a variable-size grid to improve the computing speed, and circle-selects a maximum boundary according to the correct contour of the obstacle to enable a classifier to identity the type of the obstacle. The object image detection method and the object image detection device of the invention have the advantage of being capable of improving complete circle-selection of dynamic objects and improving the accuracy of identification. The problem that an existing dynamic object detection and image recognition method has high probability of incorrect judgment, is time-consuming, and cannot be easily combined with an existing vehicle system is solved.

Description

Technical field [0001] The invention relates to an object image detection method, in particular to an object image detection method capable of improving classification efficiency. Background technique [0002] Nowadays, the dynamic object detection and identification methods used to identify various image formats can only circle and select certain parts of the obstacles in the image, and after segmenting the parts, use the method of graphic comparison with multiple known graphics The comparison can only determine what kind of object the obstacle is. Therefore, the accuracy of the comparison judgment ability will be affected by the completeness of the segmentation, which means that when the circled area is too small, each part is likely to produce discontinuous blocks. It is not easy to form a complete outline of obstacles, resulting in a large increase in misjudgment and excessive search time. [0003] In the aforementioned dynamic object detection and image recognition method, if...
