The present invention relates to a method and to a battery management system which are suitable for determining an open-circuit voltage profile (3) of a vehicle battery, dependent on a state of charge, in a vehicle. In this context, the following occur: complete discharging (S1) of the vehicle battery by vehicle-internal loads of the vehicle, sensing (S2) of a first sensed, state-of-charge-dependent voltage profile (1) during the discharging (S1) of the vehicle battery, complete charging (S3) of the vehicle battery by a charging device, sensing (S4) of a second sensed state-of-charge-dependent voltage profile (2) during the charging (S3) of the vehicle battery, and determination (S5) of the state-of-charge-dependent open-circuit voltage profile (3) by means of a weighted interpolation of the first sensed voltage profile (1) and of the second sensed voltage profile (2).

The present invention relates to a photographic correction method and photographic device of a multi-camera lens group, comprising: S1. enabling one lens group in the multi-camera lens group to capture a first image, and generating a first sharpness index based on the first image; S2. Judging whether the first sharpness index meets the preset first threshold condition, if not, enabling another lens group in the multi-camera lens group to capture a second image; S3. Based on the first sharpness The degree index acquires the number of pixels added to the first image by the second image, and completes the correction of the first image. Based on the sharpness index to evaluate whether the image of the first lens group is blurred, when part or all of the first image is blurred, a second lens with a focal length range different from that of the first lens group will be used to take a second image and replace it with the second image Or the fuzzy area in the first image is synthesized, and then under the condition of ensuring the image quality, the calculation amount of the present invention is greatly reduced, and the calculation efficiency is improved.

The invention provides a self-adaption curvelet threshold value earthquake denoising method based on local variance analysis. According to the method, on the basis that deep analysis is conducted on the characteristics of a curvelet coefficient on different scales and at different angles, a self-adaption threshold value technology is provided so that effective separation of a signal and noise can be achieved at any angle, protection conducted on non-noise components is enhanced with the help of local variance information of a curvelet area, and therefore damage to the effective signal especially the weak signal can be reduced. Practices on synthetic seismogram and land seismic data prove that the actual denoising effect of a threshold value iteration method is not ideal, the denoising effect of the method is more real and effective, and the method has the unique advantages in the aspects of noise attenuation and detail protection.

The invention discloses an embedded stability analysis method for a single-layer bracing condition of a narrow foundation pit, which comprises the following steps: (1) when a passive earth pressure rupture surface of a soil body in the pit intersects with a position below the bottom surface of the pit, the pit can be judged as narrow foundation pit; (2) the stress mode of the retaining structure under the condition of narrow foundation pit single-layer support is put forward as follows: under the condition of narrow foundation pit, the soil force on the retaining structure can be divided intotwo regions, squeeze region and passive region. (3) the upper limit value of soil force on retaining piles in classical method or elastic fulcrum method is passive earth pressure, and the upper limitvalue of soil force on retaining piles in compression zone of narrow foundation pit under single-layer support condition is modified to be soil horizontal reaction coefficient multiplied by the upperlimit value of compression deformation; (4) a formula for calculating the safety factor of embedded stability of retaining structure under the condition of narrow foundation pit single-layer bracing is put forward. The formula can be used to calculate the stability of embedded length of narrow foundation pit with single-layer bracing, and it is more suitable for the practical conditions of narrowfoundation pit.
