Embodiment

[0057]Before performing the recognition algorithm operation, first do the pre-order preparation work, such as the selection of the camera. Due to the fast moving speed of the chariot target, considering that the rolling shutter exposure camera may have a jelly effect, finally select the global exposure camera, the global exposure camera In the case of low exposure, the color saturation is higher, the image quality is stable, and the difficulty of the recognition algorithm is reduced; in addition, the frame rate and resolution must also be considered when selecting a camera. Due to the limitation of resolution and bandwidth, the frame rate is mutually restricted, and the actual selection requires Balance image quality with speed.

[0058] Before preprocessing the image, it is necessary to perform Gamma correction on the image. In armor recognition, exposure is the key factor to determine whether the armor plate can be successfully recognized. The obtained target image is divided...

Abstract

The invention relates to an armor plate recognition algorithm based on light bar matching, and the algorithm comprises the steps: firstly carrying out the preprocessing of an image, extracting a lightbar based on the light bar geometric feature constraint traversal contour, carrying out the matching of the light bar, extracting an armor plate digital pattern, and improving the recognition rate ofan armor plate through template matching; then, utilizing an image pixel coordinate system and real world coordinate conversion to obtain a control rotation angle for pan-tilt control, and solving the problem that pan-tilt control lags behind object motion; and finally, establishing a target selection mechanism model and a target tracking mechanism model, and determining a potential threat targetoutside the tracking visual field. According to the method, the problems that in the background art, the optimal hitting target of the armor cannot be determined, the false armor recognition rate ishigh, and robustness is poor are solved, a reliable recognition method is provided for armor recognition, and good market prospects are achieved.

Description

technical field [0001] The invention relates to an armor plate recognition algorithm based on light bar matching, and belongs to the technical field of visual algorithms. Background technique [0002] As the visual basis for human perception of the world, image processing mainly includes technologies such as image coding, image enhancement, image segmentation, and image analysis. It has many applications in areas such as driverless driving, face recognition, license plate recognition, and digital recognition. The Robomaster National College Student Robot Competition is a global shooting confrontation robot competition. As a global robot competition platform, the importance of visual algorithms in the competition is self-evident. Armor plate self-aiming, small rune strike, big rune Strike plays a vital role in the direction of the game; however, the lower exposure value of the traditional armor recognition algorithm will make it difficult to recognize dark areas, increasing t...
