And S02, determining component types according to the component image information, wherein the component types comprise a car light type, a car door type and a car window type.
The specific steps for determining the component type are as follows:
and matching the component image information with preset component reference image information to obtain a matching result.
Specifically, the preset component reference image refers to a component reference image which is acquired in advance and is used for comparing with the component image to judge the component type of the component image. In the present embodiment, the preset component reference image may be a preset vehicle lamp reference image, a preset vehicle door reference image, or a preset vehicle window reference image.
And judging the type of the component according to a preset rule based on the matching result.
Specifically, the preset rule is a preset component matching rule, if the component image is greater than or equal to the preset matching degree, the next step is skipped, and if the component image is lower than the preset matching degree, the next step is skipped.
The method comprises the following specific steps:
and when the matching degree of the component image and the preset vehicle lamp reference image is greater than or equal to the preset matching degree, indicating that the component image is matched with the preset component reference image, and determining that the component type is the vehicle lamp type.
And if the matching degree between the current component image and the preset vehicle lamp reference image is lower than the preset matching degree, the component image is not matched with the preset vehicle lamp reference image, the vehicle lamp type is not determined, and therefore the next vehicle door type matching step is skipped.
And when the matching degree between the part image and the preset vehicle door reference image is greater than or equal to the preset matching degree, the part image is matched with the preset part reference image, and the part type is determined to be the vehicle door type.
And if the matching degree between the current component image and the preset vehicle door reference image is lower than the preset matching degree, the component image is not matched with the preset vehicle lamp reference image, the vehicle lamp type is not determined, and therefore the next step of vehicle window type matching is skipped.
And when the matching degree between the component image and the preset vehicle window reference image is greater than or equal to the preset matching degree, the component image is matched with the preset component reference image, and the component type is determined to be the vehicle window type.
And when the matching degree between the component image and the preset vehicle window reference image is lower than the preset matching degree, the component image is not matched with the preset vehicle window reference image, the type of the vehicle window is not determined, and therefore the step of obtaining the component image is returned.
If the current component image is the vehicle lamp image, the preset matching degree is 90%, the current vehicle lamp image is matched with the preset vehicle lamp reference image, if the matching degree is 96%, the current component image is the vehicle lamp image, the type of the vehicle lamp is determined, and if the comparison between the component image and the preset vehicle lamp reference image is lower than the preset matching degree, the current component image is not the vehicle lamp image. And then skipping to the next part image for matching, if the current part image is matched with a preset vehicle window reference image and reaches a preset matching degree, indicating that the current part image is the vehicle window image, if the current part image is lower than the preset matching degree, indicating that the current part image is not the vehicle window image, skipping to the next part image for matching, if the current part image is matched with the preset vehicle door reference image and reaches the preset matching degree, indicating that the current part image is the vehicle door image, and if the current part image is lower than the preset matching degree, indicating that the current part image is not the vehicle door image, returning to the step of obtaining the part image.

Specifically, the number of measurement points is determined according to the formula N = L/k, wherein according to the formula N = L/k, when the length of the contour of the part is determined to be L, and k is a variable, the number of measurement points can be obtained. If the profile length is 3 meters and K is 0.3 meters, this indicates that one measurement point is placed every 0.3 meters.
(2) And determining the position of the measuring point according to the number of the measuring points.
Specifically, when the number of measurement points is determined, the positions of the measurement points are determined at k meters intervals along the profile of the part according to the number of the measurement points. For example, when the number of the measurement points is determined to be 10 and k is set to be 0.3 m, the measurement points are sequentially arranged on the profile.

The width of the gap between the component and the vehicle body is measured by a laser profiler or a laser sensor, and in this embodiment, the width of the gap is measured by the laser profiler.
Specifically, the formula is set as W = (L2-L1)/2, where L2 is the width of the corresponding position of the vehicle body, and L1 is the width of the component, and according to the formula W = (L2-L1)/2, the width of the component is scanned by the laser profiler using a measurement point as a calibration point to obtain the currently scanned width of the component, specifically, the width may be set in the horizontal direction or the vertical direction, or the arc width and the straight line width of the component. And then scanning the horizontal or vertical width of the part corresponding to the position of the vehicle body by taking the measuring point as a calibration point, wherein the linear width of the part corresponding to the position of the vehicle body outline is parallel to the obtained linear width of the part. And substituting the current width of the part and the horizontal or vertical width of the part corresponding to the position of the vehicle body into a formula, thereby obtaining the gap width of the measuring point.
If the linear width of the part scanned by the laser profilometer is 1 meter and the linear width of the part scanned corresponding to the vehicle body position is 1.02 meters, the linear width of the part and the linear width of the part corresponding to the vehicle body position are substituted into a formula, and the corresponding gap width is 0.1 meter.
S033, comparing the gap width of the measuring point with a preset gap width to obtain a comparison result.
The preset condition is that the gap width requirement of all the measurement points is preset, and in this embodiment, the preset condition is that the gap widths of all the measurement points are within the preset gap width standard range. The preset gap width refers to a standard gap width between a preset part and a corresponding position of a vehicle body, and is used for comparing with the gap width of the part so as to judge whether the gap width of the part meets the standard.

And S04, determining whether to send abnormal notification information to the terminal according to the component type and the comparison result.
The specific results are as follows:
and when the component type is determined to be the vehicle lamp type and the component gap width is larger than the preset gap width, indicating that the component type is the vehicle lamp type at the moment and the component gap width does not accord with the preset gap width, indicating that the vehicle lamp is assembled abnormally, and then determining to send abnormal notification information to the terminal.

Specifically, in the measurement, a laser profiler attached to a robot is moved along a predetermined position of a fixed member to generate a two-dimensional profile based on X and Z directions, and the length in the Z direction is measured to obtain the height difference of the member. The two-dimensional profile based on the X direction and the Z direction means that the laser profiler moves horizontally along the part along the X direction, the Z direction is the height direction between the part and the vehicle body, and the height of the part to the corresponding position of the vehicle body can be measured by moving in the X direction.
