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] The current dynamic object detection and recognition method used to identify various image formats can only circle some part of the obstacle in the image first, divide the part, and use the method of graphic comparison with multiple known graphics Therefore, the accuracy of its comparison and judgment ability will be affected by the integrity of the segmentation, that is, when the circled area is too small, each part is prone to produce discontinuous blocks and It is not easy to form a complete obstacle outline, resulting in a large increase in misjudgments and a long search time. [0003] If the aforementioned dynamic object detection and image recognition methods calculate the feature values ​​of each image in the segmented image and establish a logic mechanism to d...
