In some embodiments, in real situations, it may happen that the width of the path occupied by the robot on the path to be walked is greater than the actual width of the path to be walked. In order to ensure that the robot can walk smoothly, therefore, the path width occupied by the robot is greater than the actual width of the path to be walked. The path width occupied by the robot on the path to be walked and the path information to be walked, and generating an image including the path information to be walked includes: if the path width occupied by the robot on the path to be walked is greater than the actual width of the path to be walked, Then re-plan the path to be walked, and generate a corresponding path including the re-planned path to be walked based on the path information to be walked corresponding to the re-planned path to be walked and the path width occupied by the robot on the re-planned path to be walked.

The second projection image, the arrow graphic on the right is the first projection image with divergence phenomenon, the upper end of the arrow graphic on the right is the end farther from the projection device, and the lower end is the end closer to the projection device. Since the image scaling factor can be obtained according to the first projection image and the second projection image, it can be ensured that the projection effect corresponding to the corrected image including the path information to be walked in the subsequent steps is the same as the projection effect corresponding to the projection image without divergence phenomenon. .

Specifically, the image scaling factor is obtained according to the image shape parameter of the first projection image and the image shape parameter of the second projection image.

Therefore, the efficiency of determining the image scaling factor can be effectively improved.

By way of example and not limitation, the quotient obtained by dividing the maximum length of the first projection image by the maximum length of the second projection image is determined as the image length scaling factor, and the maximum width of the first projection image is divided by The resulting quotient of the maximum width of the second projected image is determined as the image width scaling factor.

Step S303: Send the corrected image including the path information to be walked to the projection device.

As an example and not a limitation, assuming that the corrected image including the path information to be walked is image A, then the image A is sent to the projection device.

In the embodiment of the present application, since the robot can correct the image including the path information to be walked according to the image scaling factor, therefore, projecting the corrected image including the path information to be walked can effectively improve the robot's path correspondence path prompt effect.
