Embodiment Construction
[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] A robust SLAM method applicable to various shaded environments in the present invention is described in detail. Such as figure 1 As shown, the specific steps include:
[0041] 1. Realize the preprocessing of image frames
[0042] For the image frame acquired by the visual front-end, first use the Canny operator to detect the edge of the image frame, calculate the continuous edge in the image, and divide the image frame into roughly the foreground area and the background area. Calculate the brightness intensity ratio, hue, and color saturation difference between the foreground area and the background area in the image frame, and finally establish the corresponding HSI color m...
