A surround view system, comprising a plurality of cameras (1-T) for capturing images of the surroundings of an object; a processor configured to obtain a bird-view image of the surroundings of the object from original images captured by the plurality of cameras (1-T); determine whether a point in the bird-view image obtained from the captured images is located in an overlapping region (A, B, C, D), wherein an overlapping region (A, B, C, D) is a region in the bird-view image composed from multiple overlapping images; and upon the condition that the point is located in the overlapping region (A, B, C, D), retrieve a blending mask corresponding to a coordinate of the point, and determine a new pixel value of the point according to the blending mask by blending pixel values of the point from said multiple overlapping images, wherein the blending mask is a map between the location of the point and the ratio of the pixel values used in said blending at this location; wherein the blending mask is based on an area selected within the overlapping region (A, B, C, D), wherein the selected area has one vertex and is a triangular area or a sector area within the overlapping region (A, B, C, D), the vertex of the selected area is the intersection of boundary lines of the overlapping region (A, B, C, D), and the blending mask of the point is further based on the ratio of an angle between a line from the point to the vertex and a boundary line of the selected area passing through the vertex to the angle of the selected area at the vertex upon the condition that the point is within the selected area. a plurality of cameras (1-T) for capturing images of the surroundings of an object; a processor configured to obtain a bird-view image of the surroundings of the object from original images captured by the plurality of cameras (1-T); determine whether a point in the bird-view image obtained from the captured images is located in an overlapping region (A, B, C, D), wherein an overlapping region (A, B, C, D) is a region in the bird-view image composed from multiple overlapping images; and upon the condition that the point is located in the overlapping region (A, B, C, D), retrieve a blending mask corresponding to a coordinate of the point, and determine a new pixel value of the point according to the blending mask by blending pixel values of the point from said multiple overlapping images, wherein the blending mask is a map between the location of the point and the ratio of the pixel values used in said blending at this location; wherein the blending mask is based on an area selected within the overlapping region (A, B, C, D), wherein the selected area has one vertex and is a triangular area or a sector area within the overlapping region (A, B, C, D), the vertex of the selected area is the intersection of boundary lines of the overlapping region (A, B, C, D), and the blending mask of the point is further based on the ratio of an angle between a line from the point to the vertex and a boundary line of the selected area passing through the vertex to the angle of the selected area at the vertex upon the condition that the point is within the selected area. obtain a bird-view image of the surroundings of the object from original images captured by the plurality of cameras (1-T); determine whether a point in the bird-view image obtained from the captured images is located in an overlapping region (A, B, C, D), wherein an overlapping region (A, B, C, D) is a region in the bird-view image composed from multiple overlapping images; and upon the condition that the point is located in the overlapping region (A, B, C, D), retrieve a blending mask corresponding to a coordinate of the point, and determine a new pixel value of the point according to the blending mask by blending pixel values of the point from said multiple overlapping images, wherein the blending mask is a map between the location of the point and the ratio of the pixel values used in said blending at this location; wherein the blending mask is based on an area selected within the overlapping region (A, B, C, D), wherein the selected area has one vertex and is a triangular area or a sector area within the overlapping region (A, B, C, D), the vertex of the selected area is the intersection of boundary lines of the overlapping region (A, B, C, D), and the blending mask of the point is further based on the ratio of an angle between a line from the point to the vertex and a boundary line of the selected area passing through the vertex to the angle of the selected area at the vertex upon the condition that the point is within the selected area.
