Abstract: Provided test method and apparatus of communication chip, device and medium. The test method of communication chip includes receiving end test method and transmitting end test method. The receiving end test method of the communication chip includes: an idle time slot of the receiving end of the communication chip is detected in a running process of the communication chip; a test vector is generated, and a standard result corresponding to the test vector is generated; a data frame containing the test vector is constructed, and the data frame is sent to the receiving end of the communication chip in the idle time slot to enable the receiving end of the communication chip to process the data frame; and a chip processing result uploaded by the receiving end of the communication chip is received, and the standard result is compared with the chip processing result.

Abstract: A method for diagnosing secure communication. Before performing a data transmission, a self-diagnosing mode is entered. Error checkpoints are checked to generate a diagnostic status. The diagnostic status is collected. An error handling mode is entered to determine whether an error exists in the diagnostic status. When there is an error, the error is shielded. The method for diagnosing secure communication solves the problem of image burn-in, and further reduces the use of non-volatile memory. Therefore, the size and function utility of the integrated circuit can be further reduced.

Abstract: The present disclosure provides a visual navigation method and a visual navigation device. The method may include steps of: obtaining a plurality of ambient sub-images for a collected ambient image based on the collected ambient image; performing a region-matching process on each of the ambient sub-images to determine a disparity between at least two of the ambient sub-images; and determining coordinates of an object in the ambient image based on the determined disparity, and performing a navigation based on the determined coordinates. In the present disclosure, the ambient image is collected by a single camera, the plurality of ambient sub-images is obtained by the micro-lens array based on the collected ambient image, and then stereo matching and three-dimensional (3D) reconstruction are implemented based on the ambient sub-images to perform the visual navigation.
