A target recognition and localization method based on self-switching of multi-view vision system

This invention discloses a target recognition and localization method based on self-switching of a multi-view vision system. The method uses a target recognition algorithm to identify and perceive the target object, and acquires local depth information based on the binocular imaging principle. Based on this local depth information, three indicators are calculated to evaluate localization accuracy: single-pixel deviation influence factor σ, depth information error rate ε, and depth dispersion ξ. Two evaluation indicators, Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity-to-Simple (SSIM), are obtained based on the local image information of the target. A target localization evaluation model is established to quantify the localization accuracy. According to the autonomous switching logic, the target recognition result and the localization accuracy evaluation score are compared sequentially to achieve autonomous switching between multiple binocular cameras with different focal lengths. This satisfies the requirements for both near-range and far-range target recognition and localization, overcoming the problems of low localization accuracy of low-focal-length binocular cameras for distant targets and small field of view of high-focal-length binocular cameras.
