Abstract: The present disclosure relates to a high-speed and low-power successive approximation register analog-to-digital converter (SAR ADC) and an analog-to-digital conversion method. Binary redundancy reassembly is performed to improve a digital-to-analog converter (DAC) capacitor array included in the SAR ADC such that the total number of capacitors included in a capacitor sub-array of the DAC capacitor array is greater than the number of precision bits of the SAR ADC, and the total number of unit capacitors included in all capacitors when the total number of capacitors included in the capacitor sub-array is greater than the number of precision bits of the SAR ADC is equal to the total number of unit capacitors included in all capacitors when the total number of capacitors included in the capacitor sub-array is equal to the number of precision bits of the SAR ADC.

Abstract: A method for sensing an object includes: collecting image data and point cloud data of the object, and acquiring an image feature of the image data and a point cloud feature of the point cloud data; generating a fusion feature by performing feature fusion on the image feature and the point cloud feature; and generating a sensing result of the object according to the fusion feature.

Abstract: An object detection method, the method includes: determining an object event image from event images collected by an event camera in the case of obtaining an original radar point cloud; obtaining, by projecting the original radar point cloud according to a pre-calibrated extrinsic matrix, relative to the event camera, of a radar, a projected point cloud of the original radar point cloud in a coordinate system of the event camera; determining an object radar point from the original radar point cloud according to a positional relation between projected points in the projected point cloud and an image contour in the object event image; and performing object detection according to the object radar point.
