An inspection system for inspecting an inspection object, the inspection system comprising: a measurement unit configured to irradiate light on the inspection object to acquire an image of the inspection object; a processing unit configured to detect an outline of the inspection object in the image of the inspection object; and an output unit configured to overlap and display the outline with reference information, wherein the processing unit is configured to: set a height inspection region with respect to a center of the inspection object based on the outline of the inspection object; determine whether a height of the inspection object is good or defective by comparing a height of the outline within the height inspection region with the reference information; the inspection system being characterised in that the processing unit is further configured to: set at least one reference point on the outline spaced by a predetermined distance from an end point of the outline; calculate a slope of the outline based on the at least one reference point; determine whether a slope of the inspection object is good or defective by comparing the calculated slope with the reference information; and perform image processing for visualizing the outline using any one of dots, dashed lines, solid lines, faces or three-dimensional shapes on the outline according to whether the height and the slope of the inspection object are good or defective. a measurement unit configured to irradiate light on the inspection object to acquire an image of the inspection object; a processing unit configured to detect an outline of the inspection object in the image of the inspection object; and an output unit configured to overlap and display the outline with reference information, wherein the processing unit is configured to: set a height inspection region with respect to a center of the inspection object based on the outline of the inspection object; determine whether a height of the inspection object is good or defective by comparing a height of the outline within the height inspection region with the reference information; the inspection system being characterised in that the processing unit is further configured to: set at least one reference point on the outline spaced by a predetermined distance from an end point of the outline; calculate a slope of the outline based on the at least one reference point; determine whether a slope of the inspection object is good or defective by comparing the calculated slope with the reference information; and perform image processing for visualizing the outline using any one of dots, dashed lines, solid lines, faces or three-dimensional shapes on the outline according to whether the height and the slope of the inspection object are good or defective. set a height inspection region with respect to a center of the inspection object based on the outline of the inspection object; determine whether a height of the inspection object is good or defective by comparing a height of the outline within the height inspection region with the reference information; the inspection system being characterised in that the processing unit is further configured to: set at least one reference point on the outline spaced by a predetermined distance from an end point of the outline; calculate a slope of the outline based on the at least one reference point; determine whether a slope of the inspection object is good or defective by comparing the calculated slope with the reference information; and perform image processing for visualizing the outline using any one of dots, dashed lines, solid lines, faces or three-dimensional shapes on the outline according to whether the height and the slope of the inspection object are good or defective. set at least one reference point on the outline spaced by a predetermined distance from an end point of the outline; calculate a slope of the outline based on the at least one reference point; determine whether a slope of the inspection object is good or defective by comparing the calculated slope with the reference information; and perform image processing for visualizing the outline using any one of dots, dashed lines, solid lines, faces or three-dimensional shapes on the outline according to whether the height and the slope of the inspection object are good or defective.
