(-215:assertion failed) i < 0是指在某个函数(函数名为getmat_)中,出现了断言错误。断言是一种常用的程序调试和错误检测的工具,其作用是在程序运行的过程中检查某个条件是否为真,如果条件为假,则终止程序并给出相应的错误信息。
在这个具体的情况中,断言错误是由于i的值大于或等于0导致的。断言条件(i < 0)的含义是i需要小于0才满足条件,但是实际上i的值大于或等于0。因此,在这个函数中,可能存在一段代码根据i的值进行了一些计算或操作,但是这个函数无法处理i大于或等于0的情况,导致了断言错误的发生。
解决这个问题的方法可以是检查函数中关于i的使用的地方,找到导致i大于或等于0的原因,并进行相应的修正。修正的方式可以是修改计算或操作的逻辑,或者增加条件判断来处理i大于或等于0的情况。另外,也可以调整调用该函数时传入的参数,确保i的值小于0。
总之,(-215:assertion failed) i < 0 in function 'getmat_'是一个断言错误,表明在某个函数中发现了i大于或等于0的情况。需要通过修正代码逻辑或调整参数来解决这个问题。

(-215:Assertion failed) j < nimages in function 'cv::histPrepareImages'
The error message "(-215:Assertion failed) j < nimages in function 'cv::histPrepareImages'" typically occurs when using OpenCV library functions related to image histograms. It indicates that the function expected a valid index for the image being processed, but the index provided was outside the range of valid image indices.
This error can be caused by a variety of issues, such as passing an invalid or out-of-range index to the function, providing an incorrect number of images, or using an image type that is not supported by the function.
To resolve this error, double-check that the indices being passed to the function are valid and within the expected range. Make sure the number of images provided matches the expected number for the function being used. Additionally, ensure that the image types being used are supported by the function.
(-215:Assertion failed) 0 <= i && i < (int)vv.size() in function 'getMat_'
This error message is typically encountered in OpenCV and it indicates that an index or iterator is out of bounds.
The error message specifically indicates that the variable "i" is less than zero, which is not allowed. This could occur if an index or iterator is being used incorrectly, or if the size of a data structure is not being checked properly before accessing its elements.
To resolve this error, you can try the following:
- Check that all indices and iterators are being used correctly and are within the bounds of the data structure.
- Ensure that the size of any data structures are being checked before accessing their elements.
- Use debugging tools to identify where the error is occurring and inspect the values of relevant variables at that point in the code.
- Consider using try-catch blocks or other error handling mechanisms to gracefully handle errors like this.
