为了更加清晰准确地检测出彩色图像的边缘，提出了一种改进的 Canny 边缘检测方法，将彩色图像从RGB颜色空间转换到颜色均匀的L*a*b*空间，用色差Canny算子来计算彩色图像的色差和色差方向。彩色直线和曲线道路图像的边缘检测效果证明了改进算子的有效性。
為瞭更加清晰準確地檢測齣綵色圖像的邊緣，提齣瞭一種改進的 Canny 邊緣檢測方法，將綵色圖像從RGB顏色空間轉換到顏色均勻的L*a*b*空間，用色差Canny算子來計算綵色圖像的色差和色差方嚮。綵色直線和麯線道路圖像的邊緣檢測效果證明瞭改進算子的有效性。

In order to detect the edge of color image more clearly and accurately, this paper presents an improved Canny edge detection method, that Canny operator based on color difference is used to calculate the color difference and color directions of color image by converting color image from RGB color space to theL*a*b*space of uniform color. The edge detection results of line and curve road color image prove the effectiveness of the improved operator.
