Abstract: An image processing method includes obtaining a to-be-processed image; and obtaining a to-be-corrected line segment, through filtering based on at least one inertial measurement unit (IMU) information and a field of view that are included in metadata, from line segments included in the to-be-processed image. The to-be-processed image includes at least one of a vertical line segment and a horizontal line segment in a first scenario photographed by a photographing device. The method further includes correcting the to-be-corrected line segment and a feature region of the to-be-processed image to obtain a processed image, where the feature region includes a background region, a portrait region, and an edge region.

Abstract: A target detection method and apparatus, a radar, and a vehicle are provided, and relate to the field of radar technologies. The method includes: obtaining a signal spectrum based on a received signal of a receive antenna of the radar; reconstructing a received signal corresponding to a target that is in the signal spectrum and that is greater than or equal to a signal strength threshold; eliminating a reconstructed received signal in the signal spectrum to obtain an updated signal spectrum, where the updated signal spectrum represents a signal spectrum that does not include the target; determining, in the updated signal spectrum, a parameter of a target that is greater than or equal to the signal strength threshold; and obtaining at least one of location information or speed information of the determined target based on the determined parameter of the target.

Abstract: A radar system includes a first radar sensor comprising a data combination system and a plurality of radar monolithic chips, wherein each radar monolithic chip includes a first radio frequency front end and a first microprocessor. The first microprocessor is configured to preprocess echo data obtained by the first radio frequency front end. The data combination system is configured to combine and transmit the preprocessed echo data, wherein a processor performs post-processing on the preprocessed echo data to generate point cloud data of the radar system.

Abstract: An image transformation method includes obtaining a first image for a target scenario by using a front-facing camera, where the target scenario includes a face of a target person; obtaining a target distance between the face of the target person and the front-facing camera; and when the target distance is less than a preset threshold, performing first processing on the first image to obtain a second image. The first processing includes performing distortion correction on the first image based on the target distance. The face of the target person in the second image is closer to a real appearance of the face of the target person than the face of the target person in the first image.

Abstract: A radar signal transmitting method, a radar signal receiving method, and an apparatus are applied to a radar apparatus. The radar signal transmitting method includes: sending a first signal and a second signal in S slots, where a phase of the first signal remains unchanged in the S slots, and the first signal may be equivalent to a SIMO signal; and sending the second signal in at least one of a time division manner or a code division manner, where phase modulation is performed, by using a step of 2πky/P, on a signal that is in the second signal and that is sent through each of m transmit antennas, and the second signal is equivalent to a MIMO signal. When P=2, the MIMO signal is sent in a time division manner. When P>2, the MIMO signal is sent in a time division manner and a code division manner.

Abstract: Embodiments of this application disclose a signal processing method, a radar system, and a vehicle. The method is applied to a radar system including an array antenna. The method includes: sequentially transmitting signals according to a first transmission sequence through M transmit antennas, where the first transmission sequence is different from a sequence that is formed by arranging the M transmit antennas based on spatial locations; receiving, through N receive antennas, echo signals that are formed after a target reflects the transmitted signals, where M and N are positive integers, and M is greater than 2; and measuring a parameter of the target based on the echo signals. According to the embodiments of this application, correlation between space and a Doppler phase shift is reduced by changing a switching order of transmit antennas.
