Parameters

Returns

• 0: success
• Other values: failure. For details, see VPC Return Codes.

Restrictions

• The width and height of the input and output images must be correctly configured. The resolutions range from [10, 6] to [4096, 4096].
• For a channel, this API can be called multiple times to set surround-view stitching parameters. However, the output resolution (dest_pic_width and dest_pic_height), stitching table type (stitch_table_type), and miniaturization type (mini_order) cannot be modified.
• When setting stitching parameters, ensure that the image ID in the stitching table is set successfully. Otherwise, the stitched output image may be abnormal. For details about how to set the image ID, see hi_stiching_ipm_table.
